I noticed that when I render "using my Renderer, or Cinema4D standard renderer" , I can change image colors while it is rendering "gamma, exposure, ..."
once the render finishes, a lot of data is lost "as if it is converted from 32 bits to 8 bits". "so dark areas appear losing a lot of data when increasing gamma, also light areas gets clamped"
this happens only once everything finishes "may be at the exit of render inner stage"
what should I do to avoid this?

could you explain what exactly do you mean with "once the render finishes"? Do you mean a certain message or the saved files? Do you talk about the bit depth you can set in the "Save" settings?

while it is rendering buckets "in the render inner stage" , everything is fine.
once all buckets are done, the whole image changes, a lot of data gets clamped "or possibly converted from 32 bits to 8 bits"

after some testing, the cause of this is the Save option->Depth->8 bits/channel,why it affects the final image even without saving?

I'm still not perfectly sure what you mean with "once all buckets are done". Do you refer to a certain stage of the rendering process?

I'm not sure which stage is it, but I think this applies after all stages are finished "after applying all videopost effects", the Save settings overrides the image "converting it from 32 bits to 8 bits" even when save is turned off

even if "Save" is disabled the final image is still displayed in the Picture Viewer and consumes memory. I guess this is why the final bit depth is applied.
