Does my ISO matter for rendering?
show user profile  Abrownbear
I am setting up my scene and trying to determine if I should use a realistic light level and realistic ISO setting.

I have read that you want to use the lowest ISO possible in photography to have a better image quality, but is this also true for rendering?

My options:
1. Set a very low ISO and make a very bright light source to compensate.

2. Set a very high ISO and a realistic (dim) light source.

Thank you for any guidance!

iso doesnt affect film grain in cgi like in real life, so i usually use it as a nominal to help light levels, maybe set between 100-200 depending.

i use the fstop and shutter speeds to more accurately determine my lighting and exposure levels.

setting it very low or very high and compensating with other lighting isnt right or realistic. iso isnt the be all and end all as the other light settings are, so use it as a standard and not a prevalent feature.

using it as a main element and compensating with your other light settings (which are more important) will result in an awkward and unreal lighting settup. try to keep as close to reality as poss.

ISO is a measurement of sensor or film speed. I don't think film grain and sensor noise are emulated in rendering software, so I'm going to guess that the answer is no.
