To add more fuel into the fire
I used and still use:
Fong diffuser clear
Fong diffuser cloud
demb flip it
self made bounce card (different sizes).
Nikon's diffusers (on sb600, 800 and 900).
If there's one thing I learned, there ISN'T BEST. They all have their places where I'd use them more efficiently and other times they are useless.
For example, and this is what I found w/
my shooting style,
*using Fong Diffuser w/ dome, is useless at distances greater then 15 feet or so (about 2.5 times of height). For that I might shoot bareflash or w/ native diffuser of the flash. Also fongs require higher flash output.
*Native diffusers are great overall, however, when all I need to do is
on-camera flash, that extra spread of light that I want to go all over the room is BETTER spread using fong or bounce card.
*bounce cards (different brands) - durability is one factor, but just like fongs might require more juice.
In my camera bag, I have all 3. Depending on event i'm shooting, I might use one or use all 3.
Good Luck
