I am not a color scientist ninja (IANACSN?) but... If I remember correctly the Dreamcolor has several different colorspace presets. So I guess it would depend on which preset you've set the Dreamcolor to. But if it is set to rec709 then your Nuke viewer should be set to the same. Since Nuke

Hey there :) Yes, if it's and sRGB monitor then the Nuke viewer should be set to sRGB. I'm not sure on the whole emulate the look of a rec 709 by setting the Nuke viewer to rec 709-thing. That sounds a bit odd to me. But then again, IANACSN. I have however seen instances when it was useful to

Andrew, Part of what you are running into is a difference in paradigms between Nuke and OCIO. Nuke has historically been *somewhat* agnostic regarding the purpose of channel data. OCIO, on the other hand, explicitly recognizes red, green and blue channels as separate from other channel types. By

Only RGB channels from the RGBA layer are affected - the alpha is not and this has been the case for several years now in Nuke. This is the correct and desired behaviour, though admittedly seems strange at first. Any other embedded layers in an exr file are (or should be) treated as linear and

Andrew, When applying a 3D matrix transformation to an RGB triplet, each output channel is constructed using weights from all 3 channels (red, green, and blue). So in this scenario, where would you expect the transform for the alpha come from? The first channel? A weighted average of all 3? Or
