If you are looking for the best flash diffuser, you should first realize that there is no such thing. It would be great to have a versatile diffuser that works in all situations, but unfortunately, it is impossible to create a design that works equally well for every application. There are several flash diffusers out there that work pretty well in the majority of situations. None of them, however, can get you fully covered. There is always something to be criticized in any diffuser.
Analyzing different qualities of diffusers, we tried to choose the ones we think are important to the majority of users. These qualities are used as criterions in our rating system. The final rank is a weighted sum of the individual criterion ratings that can be called a "versatility factor." A high final rank means that the diffuser works well in many situations, but it doesn't necessarily mean that it will work best for you and your particular task. Lower final rank means a narrower range of applications.
In this review, we've rated several diffusers currently available on the market. We will expand this list, as we review more diffusers and reflectors.
