In photography, what is dynamic range?

Dynamic range is a word that appears frequently on photography blogs and websites. And how do you define a photograph’s dynamic range? What does it imply when we talk about dynamic range?

It’s a well-known phrase that many people are unsure of what it means. At its foundation, dynamic range is the measurement of the difference between the highest and lowest values. Between the deepest black and the most blazing white, to put it another way. The dynamic range of a photograph is defined as the contrast between the brightest and darkest areas of the image.

Contrast may also be used to describe dynamic range. With a large dynamic range, the contrast between the darkest shadows and the brightest highlights is extremely strong.

It is a fact well acknowledged that cameras do not have the same dynamic range as human sight. The human eye is the best camera on the planet. However, it’s not always certain that all of the tones contrasts in a photo will be evident when it’s printed or uploaded online.

How is Dynamic Range Measured? 

“Stops” are used to assess dynamic range. Human eyes are capable of seeing about 20 stops of dynamic range in the actual world. In other words, the deepest tones we can see with our eyes at any one time are around 1,000,000 times larger than the brightest tones we can see at the same time. This explains how people are able to see both extraordinarily brilliant and extremely dark objects at the same time.

There is no substitute for the power of human sight. Even with today’s most advanced cameras, the dynamic range is limited to a maximum of 15 stops. What we can see with our eyes is nothing compared to it. And that’s just with the most expensive cameras out there.

The dynamic range of a typical digital camera is limited to 12 stops. On sunny days or in harsh light, your photos might appear bleached or too vibrant. This is an issue.. As a result of the camera’s inability to distinguish between bright and dark areas, your images will often be washed out and include deep black shadows. A deep blue sky serves as the backdrop, yet even the tiniest of shadows will be pitch dark.

However, there is a problem with the dynamic range as well. Even if your camera is capable of handling 15 stops, the majority of displays can only show 10 of them. The result is that your images may seem worse when printed professionally.

How to Improve Dynamic Range in Photos

You can make your photos seem better by increasing the dynamic range in a few different ways. In post-processing, you can tweak your camera’s settings, but you may also utilize artificial light or a specialized filter to get the same effect.

Graduated Neutral Density Filter:

You may reduce the quantity of light that reaches your camera sensor with a grad neutral density filter (GND). Gradient glass makes up the filter and it may be found in a variety of shapes and sizes. Its purpose is to keep the brightest region of the image from being overexposed due to the presence of too much light. Instead of dark shadows, you’ll obtain bright backgrounds and correctly illuminated foregrounds by utilizing one of these specialized filters.

An accurate reading of the foreground and background light meter readings are required before using a neutral density filter. If the light difference is less than one stop, you need to adjust the filter accordingly.

Make sure your scene is correctly exposed before taking a photo with your filter in front of the lens. You can always retake the image if you see something that isn’t quite perfect.

Artificial Lighting:

Using artificial light instead of available daylight is a great strategy to avoid taking images that seem bad due to overexposure to the subject matter. You may use the camera flash or additional lighting in your photograph to brighten up gloomy portions of the image. By doing this, you are limiting the amount of light that your camera can catch. Filling the darkest area with your own light instead of relying on your camera to figure out the difference between the light and dark

In landscape photography, for example, artificial light isn’t going to do anything to improve the results. For portraits and up-close shots, choose this setting instead.

Exposure Settings in Your Camera:

If your camera’s dynamic range is poor, you can try adjusting the camera’s settings. There are exposure compensation settings on the majority of current cameras. Night photography mode and bright daylight modes are available on some cameras. You may also experiment with a very low ISO setting in order to widen your camera’s dynamic range in order to better capture scenes with strong contrast.

Photo Editing:

Editing pictures is a necessary evil from time to time. In the event that you shot in RAW mode, your photos will have sufficient data for you to edit them to bring out the whole dynamic range of your subject.

Your photo’s brightness may be easily adjusted. Simply open the highlights and shadows tool. Make advantage of the slider bar in the highlights option to bring back the picture’s brightest sections before using the slider bar in shadows to bring out the contrast.

If your image still needs some work, you may use the brush tool to adjust the brightness or darkness of problematic regions. You’ll need a solid editing application for this, but you can still tweak things on your phone using basic apps.

Shoot in a Different Environment:

Wait for better weather, snap your shots at an ideal time of day, or just hide in the shadows to boost the dynamic range of your photos.

Because the light is so strong, there’s a lot of contrast between what you’re photographing and the rest of the landscape. Cloudy days or when the sun isn’t directly above may make a huge impact when it comes to composition and lighting.

Also, avoid pointing your camera straight at the sun when photographing. The picture will turn yellow due to the sun’s rays, and even the smallest shadow will be difficult to see. Keep the sun at your back to ensure that the scene is adequately illuminated and that your camera can truly capture the dynamic range that you desire.

High Dynamic Range Photography (HDR Photography)

Photographs taken with HDR photography, also known as high dynamic range photography, have a wide dynamic range. The problem is that it’s a little convoluted. To generate a quality HDR photograph, you’ll need to shoot between two and 10 shots. The key is to experiment with various exposures while taking many shots of the same object. You then use software to combine the several images to generate a final image that is far superior to anything you could have taken with the same camera.

A tripod is a need for this task. In order to avoid camera shake, you should avoid touching your camera at all. You may then experiment with different shutter speeds to create a series of images with different levels of brightness. Start with a dim light and gradually increase the brightness. This method produces a series of photographs that are virtually identical, yet capture the whole spectrum of light.

Make sure you double-check all of your photos once you’ve taken them all. Avoid having a bird fly in front of the camera or having anything else move in front of the camera so that it alters the final image you capture.

Make a composite photo by combining many images with the use of image-editing software. Unfortunately, this program is somewhat pricey. The prices of the packages range from $40 all the way up to $100. However, if you want to produce HDR photographs with an incredible dynamic range, you’ll need this program.


In other words, what exactly do you mean by “dynamic range?” It’s the distinction between your photographs’ dark and bright areas. Even the greatest cameras have limitations when it comes to capturing both darkness and brightness in the same image, making it difficult to manage dynamic range.

Contrast may be improved even on cameras with limited dynamic range by employing several techniques. There are a number of ways you may experiment with HDR photography: you can shoot in the shadow, you can use your own artificial light to lighten the dark regions, and you can edit your shots after they’ve been taken to brighten the darkest sections for a more consistent tone.
