I'm using a big diffusion frame made from lee 216 diffusion. How much light loss should I expect. Does it matter how far I bring it from the camera? Are there any diffusions which are more efficient (like the engineered rosco ones?)

Thanks,

1st page of a google search:

"Does it matter how far I bring it from the camera" - in terms of ??

anyhoo, treat the diffusion gel itself as the light source - i.e. yes it does it matter how close you put it to the subject in terms of both light intensity and effect (there is more than factor at play here)

as for efficiency - no idea ;)

Thanks, I found it on google before I found it here, but not before lots of navigating through lee's awful website. Thanks for the advice; I should have known as much but I just wanted to be sure. Looks like I'm loading up on 251 instead. Better than nothing.
