The problem is that we need to get 8 bit layered TIFs out of
Photoshop.
I think the first problem is that the Photoshop blending is profoundly
affected by the bit depth.
The second problem is that if Nuke does a 1D lookp table conversion
from one kind of RGB to another
(including bit depth upgrades), Photoshop goes via Lab so what is
happening is more like to a 3D LUT.
What happens in your case is that probably Photoshop is converting the
layers first, and then the result of the blending
modes changes the way the images look. Maybe it's an issue with layer
mask and front unpremultiplication and conversion.
For me the first thing to check would be the PS profile settings for 8-
bit RGB. Also, where do the discrepancies occur the most?
Blended layer edges? Maybe your workflow needs to be related to
manually unpremulting layers by the layer transparency and
preadjusting the transparency grays...
