i am working on a technical evlauation of a workflow, one of the partners sent me this note;
I figured I should let you know that there is some negative values in the files you provided me.
For example the filename:
pixel at position 204 4027 in the blue channel has a value of -4.4823e-05. Obviously negative light values does not exist…
Something wrong must be happening during the export.
i am used to sorting negitive pixel values when gradeing in ACES, and have not looked at the options -or- how to avoid in the first place, i just work around it
the camera is RED Dragon, it was debayered in Resolve 12.5.3 with ACES 1.02 , exported camera default + metadata = exposure/temp with no ODT to EXR half float
any thoughts would be apreacated and will forwarded on to the other folks involved.
