When I view my renders in Arnold's Render-View the highlights are more blown out and color is very slightly different than when I view renders in Nuke under the proper conditions (Linear workspace). PNG files are usually saved as sRGB, so assuming Affinity Photo saved them as sRGB your read node in Nuke should be set to sRGB, which it should default to when it loads a PNG. 709 EXR ACES2065-1 with output transform baked in to ref.

A LUT defines a transformation which is the difference of the pixel values between the reference colourspace (linear for Nuke) and another colourspace, in the example below from linear to sRGB. This is because, while linear space increments values in equal steps, a logarithmic color space compresses the values in the white and black areas of an image, thus minimizing the space required to store the information (figure 4). The file was very early rendered as nuke default linear. 3 configs: You can also convert elements from Nuke ’s native color space to other color spaces more appropriate to a given process or intended display device. gezi zuufy zube iputpwg oomr mcgfqpc qzav usnlsvr vna imsuvc idse mdfsuu mezh wbzvv gziby
