Hello, I am having this problem with PNGs from Nuke that I need to deliver in a Photoshop psd-file. This specifically concerns the shadow pass of my comp but generally there is a discrepancy on everything that is not solidly opaque.
My workflow is as follows: - I write my 8-bit PNG out of Nuke using the sRGB colorspace. - When I open the rendered PNG in Photoshop I assign the sRGB color profile and over a 'transparent' background the shadow looks to have similar density to the one in Nuke. - When I comp that layer over a white background though, the shadow is suddenly more dense than in Nuke. Also, there is a much harsher fall-off in the shadow. Is this because Photoshop treats alpha information differently from Nuke? I thought I can maybe counteract this by additional grading in Nuke but even when I grade the alpha gamma to 0.4545 in Nuke and then write the PNG I get closer but not exactly to the same result. Does anyone have a suggestion? Thanks.
