- OCIOColorSpace: ACES2065-1 to scene linear (
examples/color/ocio_aces_to_linear.oink): Carrots.exr is stored with ACES2065-1 (AP0) primaries. The Read is set to raw (no conversion) and the OCIOColorSpace converts AP0 to the working space (Linear Rec.709), which is what the Read's input transform does for you when you set it.
