OpenEXR images with linear and non-linear gamma look the same
Posted: Wed Nov 16, 2022 6:00 pm
Hello,
I have two FP16 .exr images with exact same data but one with linear gamma flag and the other one without.
Linear flag is shown in Image->Properties->ExifTool->OpenEXR as
"Channels: B half linear 1 1, G half linear 1 1, R half linear 1 1".
And the one without it
"Channels: B half 1 1, G half 1 1, R half 1 1".
They both look the same in XnViewMP, and, intuitively, I think they shouldn't.
I guess, Format setting->Read->OpenEXR->Gamma is used for both images but it should only be used for non-linear ones.
Is there any way to remediate this by taking into account linear flag set in the file?
Thank you.
