If you want to change the specular light in your setting to a softer, more diffused type of light, then it’s a good idea to use a diffuser when taking the photo. Diffusers are typically constructed out of mesh or translucent materials.
When the material is placed in front of the light source it will break up or soften and diffuse the light beam.
If you want to diffuse the light even more, you can use a finer piece of mesh or use two pieces of mesh or screen that are placed together and are slightly out of alignment. This will create a finer mesh with more holes in it.
However, if you don’t want too much diffusion in your photo, it’s recommended that you use a wider mesh material. Diffusers can be attached onto your light source unit and they can be positioned between the light and your subject.
Some types of lamps can even give off diffused light, but if you don’t happen to have one handy, then a diffuser will do the job.
Diffusers are available in various types, styles, shapes, colors, and materials. They often come included in kits with other types of lighting accessories and they can also be purchased separately for just a few dollars.
