A diffuser creates a softer flash for more appealing photos.
A flash diffuser is a device that is placed between the flash unit and the photo subject to decrease the effects of a direct flash. Often, a direct flash will leave sharp shadow lines around the subject's edge and create a flat image. A diffuser softens the flash by randomizing the rays of light it produces. The result is a softer image, which creates smoother shadows and gradients. Some flash units have built-in diffusers, but many on-the-spot diffusers can be created from everyday materials.
Instructions
1. Locate your flash unit's built-in flash diffuser plate by looking for a small pull-tab directly above the flash bulb area. If one is present, pull it outward and lay it on top of your flash.
2. Place a semi-transparent material over your flash if one is not built in. You can use many types of materials, such as bubble wrap, white grocery bags or a see-through plastic lid. Different diffusions are created by the degree of transparency and the texture of the material.
3. Turn on the flash and connect it with your camera. Aim the camera at the subject and take the photo. The flash diffuser will spread out and flatten the light produced.
4. Inspect the image produced and adjust the diffuser to increase or decrease the amount of light or the area where it falls.
