At the heart of the Canon PowerShot SD4500 IS design is a CMOS image sensor that has a resolution of 10 megapixels. The Canon SD4500IS follows in the footsteps of the PowerShot S90 by reducing the practical solution to 10 megapixels. This was done to improve image quality in low-light situations.
One piece of evidence that this is the case is that the camera has a more comprehensive sensitivity range than is typical for a small camera. This range extends from ISO 125 to ISO 3,200 equivalents. (It is important to note that in contrast to the S90 and S95, the Canon SD4500 utilizes a CMOS sensor rather than a CCD sensor.) CMOS permits better performance, which makes it much simpler to record 1080p HD video; however, this comes at the expense of some quality in the still images.)
Canon has placed a 10x optical zoom lens in front of the image sensor of the Canon SD4500. The actual focal lengths of this lens range from 6.3 to 63 millimeters, equivalent to a range of 36 millimeters to 360 millimeters on a 35mm camera. This provides a not very generous wide angle to a powerful telephoto. Throughout the zoom range, the maximum aperture shifts from f/3.4 to f/5.6.
Considering this lens’s telephoto reach, Canon has incorporated a simple optical image stabilization system inside the SD4500 IS. This technology combats blur caused by camera shake and is necessary given the lens’s telephoto reach.
The Canon SD4500 IS does not have either an optical or an electronic viewfinder; instead, the LCD on its rear panel serves as the sole point of interface with the user. The display on the PowerShot SD4500 has a pretty standard size of three inches across the diagonal and a resolution of two hundred thirty thousand dots.
In addition to still images with resolutions of up to 3,648 by 2,736 pixels, the Canon SD4500 can record full HD (1,920 by 1,080 pixels) movie clips at a rate of 24 frames per second. Furthermore, high-definition 720p (1,280 by 720 pixel) movie clips, as well as standard definition movie clips with either VGA (640 by 480) or QVGA (320 by 240) resolution, all offer a rate of 30 frames per second.
Unusually, QVGA films may also be recorded at a staggering 240 frames per second; however, they can only be played back at a rate of 30 frames per second. This results in a slow-motion effect that takes up just 1/8 of the time that would usually be required. Videos are stored using an H.264 compression format. MOV containers, and they have stereo audio included.
The evaluative metering system of the Canon SD4500, which also provides center-weighted average and spot modes, is used to determine exposures. Other methods available include spot and average center-weighted. In addition to a comprehensive collection of scene modes, the Canon PowerShot SD4500 has exposure modes such as Smart Auto and Program Auto.
Retrato, Instantâneo Noturno, Crianças e Animais de Estimação, Interior, Obturador Inteligente, Explosão de Alta Velocidade, Pouca Luz, Acentuação de Cor, Troca de Cor, Efeito Olho de Peixe, Efeito Miniatura, Praia, Folhagem, Neve e Fogos de Artifício são alguns dos outros modos disponíveis. Em uma configuração chamada Seleção de Melhor Imagem, a câmera tira cinco fotos e, em seguida, exclui todas, exceto a mais nítida.
There is a setting for handheld night photography that automatically combines many photos taken in the camera to produce one image with minimized motion blur. There are seven options for the white balance: Auto, five presets, and manual. In addition, the PowerShot SD4500 IS features a seven-mode flash strobe that offers a range of one to 12 feet in wide-angle mode and 3.3 to 6.6 feet in telephoto mode.
The Canon PowerShot SD4500IS uses Secure Digital, SDHC, or SDXC memory cards to store still photographs and videos. The available connectivity choices include composite video in either NTSC or PAL standard definition or HDMI high definition, as well as USB 2.0 High-Speed data. The power comes from a unique lithium-ion rechargeable battery called an NB-9L, and according to the manufacturer, it has a life expectancy of 150 rounds.
Canon’s ELPH series has traditionally been utilized to develop aesthetically pleasing cameras with other characteristics that consumers find appealing. The Canon SD4500, the flagship model in Canon’s ELPH range for 2010, is the latest addition to the expanding category of small cameras that feature a long zoom lens.
Depending on how you look at it, this may provide you with the best or worst of both worlds. You’ll be able to take advantage of a more compact camera that, despite its reduced size, has impressive optical performance. On the other hand, if you’re a pessimist, you’ll buy a camera that’s just a little bit too large to be considered ultra-slim, but it doesn’t have the optical zoom necessary to compete with the more giant long zooms now available on the market.
The fact that Canon could fit a 10x optical zoom lens into a camera with the same reasonable size as the Canon SD4500 should be something that you can enjoy, seeing as how I’m upbeat, and I hope that you are as well. In addition, they crammed in a lot more than simply a good zoom lens.
You’ll find a nice feature set including optical image stabilization (essential for a long zoom), a great collection of scene modes, and something that Canon calls its “HS System” (High Sensitivity), which promises better low-light performance thanks to a back-illuminated 10-megapixel CMOS image sensor and DIGIC 4 image processor. You’ll be able to find all of these things in the camera.
Consumers more interested in a “point-and-shoot” experience are the target audience for the Canon SD4500 rather than photography aficionados.
Canon PowerShot SD4500 IS Design
It should be no surprise that the Canon SD4500IS is a dapper little ELPH. If you weren’t any wiser, you could conclude that its aerodynamic properties were taken into consideration during its design: This camera is quite streamlined, with only a few little protrusions here and there.
The 10x optical zoom lens of the Canon SD4500 may be stowed away flat inside the body when it is not in use, making the camera very pocketable. Although they are flush with the camera’s body, none of the controls are complicated to operate. The corners have been softly rounded off, giving it an air of refined sophistication.
As was noted before, the Canon SD4500 is reasonably pocketable for a long-zoom camera, as it has a thickness of less than an inch (0.88 inches to be exact), making it more pocketable than the majority of digital cameras with a 10x zoom. In addition, the Canon SD4500IS isn’t very hefty, but it weighs roughly 6.7 ounces when combined with its battery and memory card.
Although it’s straightforward for the hands to grip, there isn’t much in the way of finger rests that are ergonomically sound. There are three openings on the Canon SD4500: one on the bottom of the camera for the memory card, another on the base for the battery, and one on the top for the SD card itself. The HDMI output and combination USB/A/V port of the Canon SD4500 may be accessed through a compartment on the side of the camera that is located above the hook for the wrist strap.
When this article was written, it was only offered in brown color with silver accents, making it reasonably unusual. (The editor would like to point out that it is now also offered in silver.) So you’re in luck if you want to dress in earthy tones, whether you identify as a male or female. Even if it isn’t, the selection of styles is pleasing to the ear. The image that comes to mind is of a thin bar of chocolate wrapped in a thin layer of copper foil on the rear panel.
Canon PowerShot SD4500 IS Controls
The exterior buttons on the Canon SD4500 are nearly flush with the camera, as noted before, but they are large enough that you won’t have to make repeated passes through them to activate the feature you want to use.
The Canon SD4500 contains a variety of capabilities, but the majority of them are locked away in the camera’s menu, where the user cannot access them. External controls are minimal. A sliding Mode switch with just three options—Movie, Photo, and Smart Auto mode can be found on top of the camera. After that is a Power switch, and then there is a Shutter button within the Zoom ring of the camera.
On the rear of the Canon SD4500, you’ll discover a sizable button labeled “Movie.” This is a convenient control, as it allows you to begin recording a movie right away, regardless of the model that is now active on the camera.
Underneath it is a four-way controller or dial that allows you to set the self-timer and adjust the display, flash, and focus settings. The controller may also be used as a scroll wheel, allowing for more straightforward navigation of the camera’s menus and photo galleries.
Essa roda de rolagem está incluída em muitas das câmeras minúsculas da Canon e ajuda a tornar a navegação nos menus e a reprodução de imagens mais simples.
A Function/Set button can be found in the center of the scroll wheel on the Canon SD4500. Pressing this button brings up an on-screen menu on the left side of the 3-inch LCD.
Abaixo da roda de rolagem, você encontrará os botões que permitem acessar os modos Menu e Reprodução na Canon SD4500. Dada a quantidade de espaço que a Canon tinha para trabalhar na parte traseira da Canon SD4500 de 4 polegadas, parece que ela poderia ter se beneficiado de alguns controles externos adicionais, mesmo que isso significasse reduzir o tamanho dos botões.
Some buttons with more area to work with, like the one for recording movies, might have been made smaller without causing too much of an issue. You will spend most of your time exploring the camera’s on-screen menu in search of customized settings; it would have been a little bit more user-friendly if a few more of the camera’s functions were available via external controls.
Canon PowerShot SD4500 IS Lens
The Canon SD4500 features a telescopic 10x optical zoom lens with a focal length ranging from 36mm to 360mm (35mm equivalent) with a focusing range extending from 2 inches to Infinity (normal AF). However, this lens does not have a wide-angle perspective, which goes against the trend of the past few years. It is lacking.
Macro focusing may be achieved with the Canon SD4500IS up to a distance of 0.4 inches from the subject. You can set the camera to focus in macro, but if you choose the Smart Auto mode, it will concentrate in macro for you automatically. In addition, the ring may be turned a certain amount to switch between two different zoom speeds.
When set to a wide-angle mode, the lens has a maximum aperture of f/3.4, but when put to telephoto mode, it has a maximum aperture of f/5.6. Canon’s image stabilization technology is built inside the SD4500IS, indicated by the “IS” in the model’s name.
Você pode escolher entre três modos diferentes
contínuo, que compensa o jitter continuamente e fornece uma visualização na tela da estabilização em funcionamento; disparar apenas, que ativa a estabilização assim que você pressiona o obturador (esse modo é a opção mais eficiente e eficaz); e panorâmica, que ignora o movimento horizontal e estabiliza apenas o movimento para cima e para baixo (caso contrário, a câmera tentaria compensar o movimento panorâmico).
You also have the option to disable the picture stabilization. When Then, which to Movie mode; the only options you’ll have to select are Continuous or Off.
No SD4500IS, a Canon tem uma variedade de modos de disparo típicos; no entanto, o modo de prioridade do obturador, o modo de prioridade de abertura e o modo manual não estão incluídos.
There are three things available for selection on the sliding Mode switch on the top of the camera: Movie, Automatic, and Smart Auto.
Destaque com Cor
Even though I was entirely focused on orange when I made the color pick, thinkers still displayed traces of red in the flag, yellow in the shot, and fake wood grain even though I had already settled on orange. The orange could be separated once the intensity was turned down to -4, with only a trace of the color left in the photograph.
Meus modos de cores
The My Color mode on your Canon camera provides you with a comprehensive set of tools to manage the color of your photographs. These tools range from clear filters that can be set and forgotten to more complex color isolation capabilities. If you want to apply color effects to the entire image, you can select Dark skin tone, as well as sepia, black and white, positive film, neutral, vivid, vivid rid blue, and vivid green. If you want to apply color effects to the entire image, you can select Vivid.
In addition, there is a Custom color option that you may build on the menu by picking the degrees of Contrast, Sharpness, Saturation, Red, Green, Blue, and Skin tone. This setting is also available. The CanonUnfortunately, the the4500 can only preserve one of these user-defined color modes at a time. Still, it will remember the most recent custom option you used even after the camera is powered down.
The Custom setting is beautiful for those who enjoy playing with the photos they take, while the defaults should be plenty for everyone else. The Canon SD4500 contains a mode called Color Accent that can be found in the Scene mode menu. This mode is useful when you want to highlight specific colors in a photograph while converting the rest of the scene to black and white.
Holding down the Menu button causes the Canon SD4500 to create a small white box in the middle of the display. Learning how to use this feature is not very difficult. Aim the box at the color you want to single out, and as soon as it recognizes it, you’ll be able to change the level of prominence it has among the black and white backdrop. A value of -5 will only show a very faint hue, and as you go closer to +5, it will get noticeably darker. It adds a lovely bit of originality.
The Color switch mode is one of the Scene modes found on the SD4500IS. Using this option, you may create a more surreal effect. You will get a little box on the screen at which to aim a color, and there will be a pair of boxes at the bottom that will allow you to pick the color that you want to serve as a replacement, as well as the color that you want to replace. The procedure is quite similar to the Color accent procedure.
Você precisará focar a câmera nas cores em questão enquanto usa simultaneamente o controle de quatro direções para alternar entre as duas caixas para escolher a cor e sua substituição. Depois de tomar sua decisão, você também poderá ajustar o nível de mudança de cor usando um mostrador com uma escala que varia de -5 a +5 na mesma escala de dez pontos. Embora não seja um substituto perfeito, ainda assim é possível se divertir com ele.
HD Filming and Recording There are also several Movie modes available on the Canon SD4500IS, including two high-definition ways: 1,920 x 1,080 at 24 frames per second (fps) and 1,20 x 720 at 30 fps. Files within addition, files extension MOV that are n the computer-friendly H.264 format are used to record videos.
Você pode começar a gravar em qualquer modo pressionando o botão vermelho Gravar na parte de trás da câmera ou pode alternar a câmera para o modo de filme, o que lhe dá acesso a várias funções diferentes relacionadas ao filme. De qualquer forma, você pode começar a gravar pressionando o botão vermelho Gravar na parte de trás da câmera.
At the maximum possible quality, video is caught at a bit rate that is aof5 Mbps; however, the bit rate reduces rapidly as you go down to lesser resolutions.
It would be best if you were satisfied seeing the results on a high-definition television or a large computer display. Still, you should be aware that you are not purchasing a camcorder replacement: ResulNevertheless, they fairly depressor a câmera de apontar e disparar.
When played inside, the video is rather loud, and when played in brighter locations, the highlights are commonly overexposed. However, even 24 frames per second seem to do a decent job of handling motion despite this.
While filming in Movie mode, you can access various Scene settings, including a miniature effect, color accent, and color exchange. You can also use the same set of My Color settings that you can access while shooting still images, such as vivid and cheerful, giving you more creative control over your photos. When recording, you now have a few more creative alternatives thanks to this thoughtful addition, which is a lovely touch.
The slow-motion option, which takes footage at 240 frames per second despite having a resolution of just 320 by 240, is sure to be a hit for those who like watching sports at a rapid frame rate. VideoUnfortunately, it the of poor quality, and there is no accompanying soundtrack; nevertheless, this is parred fois parred-course when using slow-motion settings. This model is a wonderfulbeautifulive for studying golf swings or capturing subtle facial expressions in your little sports star if you are ready to squint a bit.
The zoom lens of the Canon SD4500 may also be used while recording; however, I discovered that it frequently lost focus while zooming in and out. Again, this is not an unusuaccurren; it appeared to be more prominent on the Canon SD4500. You will also have the option to record at VGA and QVGA at 30 frames per second; however, unless you are pressed for capacity on your memory card, it is highly recommended that you avoid using these lower-quality settings.
Canon PowerShot SD4500 IS In addition to these modes
Because the Canon SD4500 comes with a wide variety of Scene settings, the camera should be able to cater to various preferences. In addition to the more conventional shooting modes such as Portrait, Kids, Snow, Fisheye, and Fireworks, some more creative options include Miniaturize and Posterize.
NightScene Light for handheld use
I was able couldassable a picture of the school Christmas pageant by using the Handheld NightScene setting on my camera. However, the photograph is somewhat noisy. It was necessary to increase the ISO to 3,200 on the Canon SD4500 since the alternative was not taking any photos.
Canon markets the SD4500IS as a High-Sensitivity camera; the device includes Scene settings that provide increased shooting possibilities when used in low-light environments. For example, you can select light mode, which takes a shot with a resolution of 2.5 megapixels at a high ISO, or the Handheld NightScennight scenic takes a series of photographs with full resolution all at once into a single image.
I utilized this mode inside an utterly dark auditorium, and the only thing that needed to be photographed was a stage that was lit up. I was satisfied with the results. When the alternative is having nothing at all, how can you complain about the photographs being loud and a little blurry?
Those interested in face detection will also discover alternatives for smile and wink detection shutters. The former takes a picture whenever your subject grins, which is pretty standard nowadays. However, I think this function is more of an exciting novelty than a genuinely useful one. The detection of winks is somewhat more helpful.
It is employed in a mode known as self-timer, in which the photographer presses the shutter button, moves in front of the camera, and winks before the picture is taken. It performed just as it was claimed to, and there is a sufficient delay so that you are not captured on camera blinking.
There is also an option known as Face Self-timer, which triggers a countdown to the photo’s shutter release whenever it detects a new face within the frame. You can take anything from one to ten pictures simultaneously with the Face-detection modes to be confident that you have captured the exact moment.
Canon PowerShot SD4500 IS Function menu
In specific ELPH designs, Canon has kept the function menu as a wheel, a less intuitive design. It requires more effort and is not as intuitive as other options. (The actual menus are presented in a 16:9 aspect ratio, whereas the output from the A/V Out connection is in a 4:3 aspect ratio.)
Menus. An on-screen menu called the Function menu allows users to access most of the Canon SD4500’s features. However, this can sometimes make it a bit awkward to operate, even though it is partially compensated for by the camera’s scroll wheel, which enables quick navigation.
When you are in still mode, pressing the Function button will allow you to access several options arranged along the left side of the 3-inch display. To make any necessary adjustments, move the controller to the right, scroll through your available options, and then move it to the left again to commit your selection. You can save your settings by repeatedly tapping the Function button and immediately resume shooting after doing so.
If you press the Shutter button on the camera while the Function menu is open, the camera will take a picture using the most recent option that you used and will keep the Function menu shown on the screen. Because of this, it is much simpler to return to a setting that you only want to utilize for one or two shots since it reminds you of the adjustment you previously made.
Canon PowerShot SD4500 IS Menu
When you press the Menu button, the relatively standardized and well-known tabbed Menu system will be brought up. (The actual menus are presented in a 16:9 aspect ratio, whereas the output from the A/V Out connection is in a 4:3 aspect ratio.)
The in-camera menu is where Canon places more fundamental options, such as the Flash, image stabilization model, and digital zoom control. This screen contains two tabs: the first is for basic photo settings, and the second is for basic camera settings, including volume controls and LCD brightness adjustment. You may jump back into still photography anytime while exploring the menu by pressing the shutter button on your camera.
The Menu contains a few complex components, such as the separation of the Color switch and Color accent functions from the remainder of the Colors modes that were just discussed.
The fact that there is a Super vivid choice in the Scene mode, yet it seems to shoot images at the same intensity as the Vivid setting that is accessible in My Colors, is another peculiar aspect of this camera.
Canon PowerShot SD4500 IS Storage and Battery
The Canon SD4500’s NB-9L battery pack is rated for a rather pitiful 150 shots, which is way below average and can almost get you through a day’s worth of shooting if you don’t have a heavy shutter finger and don’t shoot many videos. However, this is only the case if you don’t shoot many videos. Storage: The Canon SD4500’s built-in memory card slot can hold up to 32 GB of
Because it uses a proprietary battery, you won’t be able to buy AA batteries if you run out of them. In addition, the battery may expire on you soon if you are an ardent shooter; therefore, you should always have a backup battery and an AC charger available. Finally, the memory card door, located on the other side of the bottom of the camera from the door that accesses the storm, is a new feature that may be found in PowerShot cameras.
The Canon SD4500 does not have any internal memory. However, it can record SDHC and SDXC cards with a larger capacity. Therefore, a class 6 or faster card is suggested when filming high-definition videos. Because it is also an Eye-Fi-connected camera, owners of the wireless SD card will receive some additional benefits, including the Canon SD4500 will remain turned on until the Eye-Fi card completes its wireless transfers. Additionally, it allows you to turn off the Eye-Fi card’s WiFi radio to preserve battery life and to check the display of the Canon SD4500 to see which films and photographs have already been uploaded.
Canon PowerShot SD4500 IS Shooting
The Canon SD4500 was used for activities, including Christmas pageants, birthday celebrations, and other trips. These activities should be recognizable to anybody participating in the parenting circuit.
The responsiveness of the camera itself is satisfactory. Although it starts up a little more slowly than some of the other tiny cameras I’ve tested, it’s not a terrible choice for a long zoom. Also, the delay between shots is reasonable, so I didn’t become annoyed between pushes of the shutter button.
The three-inch display is quite sharp and has a great viewing angle, so it won’t be difficult for you to compose your snapshots. Because it is a widescreen display, the left and right sides of still pictures are obscured, and the space is filled in with data from the camera. When recording videos, the entirety of the display is utilized for the purpose.
No lightning? Even though there was very little Light in the scenario, Smart Auto did not want to use the flash since it would have washed out the skin tones. On the other hand, there is motion blur and soft focus because the moment was not used.
When using Smart Auto, I found that the Canon SD4500 was reluctant to utilize the flash, which was one of the things I noted about the camera. If there were some light already present, the camera would frequently throw caution to the wind and rely on your steady hand, the camera’s image stabilization (which I kept to Continuous), and a subject that remained motionless to take a picture without using the flash.
Now, nobody loves the Light, and it’s a digital camera Holy Grail to banish it totally, but the Canon SD4500 couldn’t quite offer blur-free shots without using the flash even when it was turned off. So smart Auto’s only choice is to turn off the moment rather than manually trigger it. I respect their bravery, but Canon’s High Sensitivity is not nearly as advanced as it needs to be.
Best? The flash fires during the first shot, which was taken using Smart Auto. The flash was turned off for the second photo, which was taken in “Best Image Selection” mode, resulting in a more natural-looking snapshot with a somewhat blurrier focus and a reduced resolution of 2.5 megapixels.
At least for Canon cameras, one of the more recent shooting modes is Best Image Selection. In this mode, the camera takes a series of pictures with a resolution of 2.5 megapixels and selects the one with the best exposure. I used the Smart Auto mode to take the same image.
In general, the Canon SD4500 captured some excellent photographs, and, in comparison to other compact cameras, it offers a greater degree of creative control in dim lighting. And if you’re serious about obtaining images of the kids more likely to be in focus, there’s always the Kids and Pets option, which uses the flash a little bit more frequently than the other shooting modes.
Canon PowerShot SD4500 IS Playback
The Canon SD4500 has various Playback options, which may be used to examine and edit photographs saved to a memory card.
You may use the four-way controller to select which image you wish to keep by using a function called “Smart Shuffle.” This function takes four alternative pictures the camera considers comparable and places them on display in a circle around the main picture (this only works when the camera has fifty or more images to work with). It’s an excellent, non-linear way to look through your photos, and I like it.
The filtered Playback option, which will play photos back by category (such as individuals), date, or by playing back just stills or only movies, is sure to be a hit with those who are more inclined toward the organization. In addition, you can select a slideshow with one of six different transition effects (or no transition effects).
To bring back lost features in some regions of an image, you may use the in-camera editing feature known as Intelligent Contrast to adjust the level of brightness, which can be set to High, Medium, Low, or Automatic. After the fact, you may also make adjustments to photographs, such as red-eye removal, image trimming and resizing, and the application of My Color effects.
My aspirations for a pocket-long zoom were satisfied to a large extent by the Canon PowerShot SD4500. I liked how lightweight it was and how long the telephoto lens was, but I wished it had a wider-angle setting to take better pictures inside.
Canon PowerShot SD4500 IS Quality of the Lens
In terms of sharpness, the Canon PowerShot SD4500’s wide-angle end of the zoom reveals a very slight decrease in the edge in the four corners of the picture compared to what we observe in the center.
Even though it’s not very noticeable, the suppleness extends toward the middle. When using the maximum amount of telescopic zoom, the corners are marginally more blurry than the center, which is also a tiny bit blurry. However, this is a remarkable performance when taken as a whole.
Distorção da Geometria
At full wide-angle, we detected very modest barrel distortion (0.4 percent), and at telephoto, we found almost no distortion; there wasn’t even one pixel’s worth of distortion. But, again, this is because the image processor in the Canon PowerShot SD4500 handles geometric distortion very effectively.
Aberração de Cor Cromática
Chromatic aberration at wide-angle is about as bad as it gets in terms of the number of pixels, but the pixels themselves are brilliant. The amount of distortion is comparable throughout the whole telephoto range.
Canon PowerShot SD4500 IS a Macro
In the macro mode of the Canon PowerShot SD4500, fine details are captured at the center of the frame; nevertheless, blurring and chromatic aberration are both significant and invade well toward the center of the frame (a standard limitation among consumer digital cameras in macro mode). The smallest area that must be covered is 1.02 inches by 0.76 inches (26 millimeters by 19 millimeters), which is not very much.
The flash on the Canon SD4500 has problems throttling down for the macro-region, which results in an uneven exposure due to the lens casting shadows on the subject. However, even if the direction is slightly inconsistent when the flash is not used, the results are much better.
Canon PowerShot SD4500 IS Quality of the Image
The Canon PowerShot SD4500 generated pleasing color, with only a hint of oversaturation in colors like reds, blues, and greens, which were quite brilliant. (Although some of the yellows are a touch lacking in saturation.)
There is a tiny shift in hue for hues such as yellow and cyan. While lighter skin tones tend to lean more toward pink, darker skin tones have a hint of warmth to them. Despite this, pretty impressive performance overall.
The results of using the Incandescent option, which generated a highly pink color, were handled considerably better by the Manual and Auto white balances than by the Incandescent setting. The Auto setting has a very slight pinkish tint, but the Manual mode has a very slight yellowish tint and a more natural feel overall.
On the resolution chart we have in our lab, we can see clear line patterns down to around 1,800 lines per image height horizontally and approximately 1,700 lines per picture height vertically (though more designs are starting to get a little distracting).
Also, take note of the dead and hot pixels that have not been fixed. Around 2,300 lines per image height were the point at which the pattern disappeared utterly.
Even though the camera had to raise its ISO to 800 to obtain the desired result in our manufacturer-specified tests (displayed on the right), the results were still pretty bright at the Canon stated distance of 12 feet. Although the ISO was increased to 800 for this test, the telephoto test scene was still reasonably well-lit at 6.6 feet.
The detail is excellent, if a little fuzzy, at ISO 125 and 200 and is still pretty clear at ISO 400. Noise levels are moderate.
At ISO 400, there is a minuscule amount of chroma noise, which refers to color noise; nevertheless, luminance noise and efforts to control noise become more annoying at ISO 800 and above. See the “Printed outcomes” section for further information on how this impacts prints.
O desempenho da Canon PowerShot SD4500 IS
Tempo de inicialização
Leva cerca de 3,7 segundos para a Canon SD4500 ligar e capturar uma foto depois de ligada. Isso fica em algum lugar no meio do pacote para modelos de zoom longo.
The delay in shutter actuation during full autofocus is somewhat long, clocking in around 0.68 seconds for wide-angle and 0.79 seconds for full telephoto. The prefocus shutter latency comes in at 0.104 seconds, which is also slower than the average but is still relatively swift.
Tempo em Ciclos
In Single-shot mode, the cycle time is reasonable, with a picture taken once every 1.97 seconds. In Continuous mode, the SD4500 IS takes an image that is very large or very fine once every 0.39 seconds, equivalent to 2.57 frames per second. However, it also has a High-Speed Burst mode that takes pictures at a reduced resolution and can take photos at a much faster rate of 0.16 seconds, equivalent to 6.35 frames per second.
Após uma descarga de energia total, o flash na Canon PowerShot SD4500 recicla em cerca de 6,5 segundos, o que é quase o normal.
Foco automático com pouca luz
Without turning on the AF-assist lamp, the camera’s autofocus mechanism was able to focus in conditions with a light level of slightly under half a foot candle. However, the camera could focus on situations without Light when the lamp was turned on.
Velocidade de transferência USB
The Canon PowerShot SD4500 has download rates that are relatively quick when it is connected to a computer or printer using USB 2.0. For example, we recorded a value of 7,618 KBytes/second.

The Canon PowerShot SD4500 IS an elegant and svelte long zoom designed to appeal to the casual point-and-shooter user. The lack of aperture and shutter priority will be upsetting to more experienced photographers, but casual users should have fun experimenting with the many scene and color settings available. The camera makes a lot of claims about its ability to work in low Light. While it isn’t always able to give the sharpest image when the lights go down, the Canon SD4500 triumphs over some challenging lighting circumstances.
We were a little dissatisfied with how long the battery lasted. Therefore we think it makes sense to recommend bringing an extra battery. Printed results are a little better, with the lowest ISO setting capable of making good 11×14-inch prints. However, the rendering of fine detail, exceptionally light to medium-colored hair, is a weak point of most CMOS sensors. It shows in 100 percent magnification when viewed on a computer screen.
Fortunately, the results are slightly better than when viewed on a printed screen. This has been a problem with hair for quite some time due to super-high resolutions, and the recent conversion to CMOS has created a general rise in sensor noise. However, it appears that Canon’s decision to reduce the number of megapixels to 10 was the right one. So those who print no more than 11 inches by 14 inches ought to be satisfied. If you’re unsure, you can always download some of our test photographs and try printing them out.
Prós e contras
- Gravação de botão de obturador de filme dedicado em HD a 1920 x 1080 a 24 quadros por segundo
- 10x optical zoom in a tiny camera that can easily fit your pocket.
- Grande tela LCD medindo 3 polegadas.
- The display has a decent viewing angle Display is legible in direct sunlight.
- A curta duração da bateria
- Sem modos de exposição manual
- A disadvantage of the present CMOS sensor architecture is that it produces a softer hair image, remarkably light and red.
- O flash eleva o ISO para 800, o que resulta em perda de detalhes.
