This is a response to a question on VFXTalk.
Nuke calculates in linear space and Photoshop in the Working Space color space (usually sRGB).
Thats why adjustments like curves levels and stuff doesn’t match up between the different applications.

If you want to use the same settings in Nuke colorLookup as Photoshop Curves you need to calculate them in the same color space. To achieve this you convert from linear in nuke to the color space you use in Photoshop apply your colorLookup and then convert back to linear space.

This is an alternative method of doing edge-detection in Nuke.
