octane physically correct to the eye or to a camera?

Was wondering if the images made by octane are possibly high dynamic range or a simulation of a camera can see. Maybe it would be possible to render bracketed images?

use exposure to bracket

octane renders in HDR floating point, like other unbiased engines.
i don't understand what bracketing is though, never heard of it... ?

thanks gk. Why not "f-stop" ?


radiance bracket just means evenly spaced out exposures http://en.wikipedia.org/wiki/Bracketing
i wanted to seem smart so I used that term.

either one works.
f stop or exposure, I usually tinker with exposure on generating 32bit images, but as rad mentions you got the bitdepth already.

Bracketing is a technique usually used in photography for creating HDR images, something that octane does by default, though we can't set save them that way...

Bracketing can also refer to focus or whitebalance but in octane there is no need to do bracketed focus as you can just turn the apperture down/off.

Not sure about whitebalance though.
