Camera flash diffusers are external flash add-ons that help to soften or spread out the flash, which results in a more flattering light for the subject. It can also limit shadows that an external flash can create. When shopping for a diffuser, try to find one that is adjustable enough to fit a number of different kinds of external flashes. You want a tight enough fit so that you limit your light leakage. Does it fold down easily so it fits in a camera bag? How durable is it? Also, consider the diffuser rule of thumb: The larger the diffuser, the softer the light you’ll end up with.
