I see people (mostly novices) asking here and there about the diffusers. Which one is the best? I know the answer : there is no such thing. BUT! I did put a lot of thought in analyzing what people are looking for in a diffuser. Came up with a system to actually rank diffusers. The rating is subjective, so please read criterion definitions to understand how the final score is calculated and what it represents. In short, I defined the "best" as "the most versatile". I could say the biggest is the best, or the lightest is the best, but that would be just another different ranking system, which also probably would make sense So, here is my The Best Flash Diffuser list. It's not final. I'll add more. Hope this will help some of the beginner photographers. Any healthy criticism is welcome .
