What Are Diffusers in Photography? (And How to Use Them)

The manipulation of light is essential to the practice of photography, which is an art form. Photographers are able to achieve the appropriate atmosphere, draw attention to specific elements, and get rid of undesired shadows by controlling the light.

Diffusers are an essential piece of equipment that must be utilized in order to accomplish these goals. In this piece, we will dig into the subject of diffusers and discuss the various ways in which using one might improve your photography.

Understanding Light in Photography

Before we go into diffusers, let’s first take a little moment to discuss the importance of light in photography. Light is the most crucial element in every shot.

It has an effect on the image’s exposure as well as its colors and general ambiance. Photographers are able to mold their vision and create engaging sights by adequately manipulating the light in their images.

What Are Diffusers?

In photography, diffusers are tools that are used to modify and disperse the light coming from a certain source. They are often made of transparent materials or surfaces, which enable light to flow through while softening the light’s harshness and intensity.

Diffusers assist in generating a more equal and pleasing light by doing so, which eliminates shadows and decreases glare. They achieve this by scattering the light.

Types of Diffusers

There is a wide variety of diffusers to choose from, and each one is designed to do a specific task. Let’s take a look at some of the ones that are utilized the most frequently:

Diffusers for Softboxes

Large enclosures composed of transparent fabric or material are what make softbox diffusers their namesake. They can be attached to studio strobes or off-camera flashes and generally have a square or rectangular form.

The light that is produced by softboxes is soft and diffused because the light is dispersed across a greater surface area. This results in softer shadows and a reduction in contrast.

Umbrella Diffusers

Umbrella diffusers are economical and adaptable solutions for dispersing light. They are made up of a reflecting umbrella that is covered in a fabric that is see-through.

Umbrellas have the ability to disperse and diffuse light, making them particularly useful when used with other lighting techniques such as flash photography or continuous illumination.

Panel Diffusers

Large, flat surfaces that are formed of materials that disperse light, such as cloth or acrylic, make up panel diffusers. In order to mitigate the effects of the intense sunshine, they are frequently employed in outdoor photography.

Panel diffusers are available in a wide variety of sizes and forms, and they can be mounted on supports or carried in the hand.

Reflector Diffusers

The functions of a diffuser and a reflector can be combined in one device called a reflector diffuser. They are composed of a reflective outer surface that is enclosed by a core panel that is see-through.

In photography, the use of reflector diffusers gives photographers more control over the lighting settings they employ by allowing them to regulate both the diffusion and reflection of light.

How Do Diffusers Work?

The light that travels through diffusers is dispersed and diffused as it travels through the device. When light comes into contact with a diffuser, it is split in several different directions, which results in an illumination that is more even and aesthetically attractive.

This procedure helps to lessen the severity of the shadows, cut down on the glare, and provide light that is flattering and draws attention to the subject.

Benefits of Using Diffusers

The usage of diffusers in photography has a number of advantages, including the following:

  • Reduces the intensity of the lighting conditions
  • It lessens the contrast and the shadows.
  • Produces light that is uniform and attractive; enhances the subject’s features and textures; lends portraiture an air of naturalism and expertise;

Tips for Using Diffusers

Take into consideration the following pointers to get the most out of your diffusers:

Adjusting the Location of the Diffuser

To obtain the desired look with the lighting, try experimenting with a variety of various locations and angles. A softer light may be achieved by positioning the diffuser closer to the subject, but more contrast can be achieved by putting the diffuser further away from the subject.

Controlling the Amount of Available Light

In order to exert even more influence on the light’s intensity as well as the temperature of its color, diffusers can be used in conjunction with other types of light modifiers, such as grids or gels. This enables a greater degree of creative control over the image that is produced.

Examining the Effects of Several Differing Diffusers

Experiment with a variety of diffusers to learn about the specific qualities offered by each type. Because every diffuser creates a unique quality of light, you will need to experiment with a variety of possibilities in order to discover the one that works best with both your vision and the subject you are photographing.

Common Mistakes to Avoid

When working with diffusers, it is imperative to steer clear of the following typical errors:

  • When the diffuser is placed too close to the light source, it causes the light to be diffused too much.
  • When compared to the size of the topic, the diffuser being used is inadequate, resulting in uneven illumination.
  • Use diffusers of varying color temperatures without first adjusting the white balance of the lighting before doing so.


Light may be controlled and shaped in many different ways with the help of diffusers, which are vital tools for photographers to have. They generate pleasing and even lighting by diffusing and softening the light, which ultimately contributes to an improvement in the overall quality of your images.

Experimenting with various kinds of diffusers and the location of those diffusers will open up a world of creative possibilities, and the resulting photographs will be intriguing.


Q. Do diffusers only work in a studio setting?
A. Diffusers can be used both indoors and outdoors. While they are commonly used in studio photography, they are also beneficial in outdoor settings to soften harsh sunlight and minimize shadows.
Q. Are diffusers only used with artificial lighting?
A. No, diffusers can be used with artificial lighting sources, such as studio strobes or flashes, as well as natural light sources like the sun. They help soften and diffuse the light regardless of its origin.
Q. Can diffusers be used with smartphone photography?
A. Yes, there are diffuser attachments available for smartphones that can help soften the light emitted by the built-in flash or external smartphone flashes. They can improve the quality of smartphone photographs by reducing harsh shadows.
Q. How do I clean and maintain diffusers?
A. The maintenance of diffusers depends on their material. Fabric diffusers can be gently cleaned using a mild detergent and a soft cloth. Acrylic or plastic diffusers can be wiped clean with a soft, lint-free cloth. Regular cleaning will help maintain their effectiveness.
Q. Can I achieve the same effect as diffusers in post-processing?
A. While some lighting effects can be simulated in post-processing, diffusers offer a more organic and natural look to the light. It’s challenging to replicate the same level of softness and evenness in software, making diffusers a valuable tool during the actual photography process.
