Output EXR is so much darker than the output PNG, same scene, same setup!

Hi

Basically I most of the times render out to PNG, single of sequences, but now I m about to render out something big and I wanted to "bake" all render passes into one EXR to edit it freely in Photoshop. This is not a big problem as such, as I can render out to both PNG and EXR, but I wonder why the EXR is so much darker than the PNG. I guess it may have something to do with colors, colors space or numbers of colors or something, as PNG is RGB 48bit and EXR is Full Float 32 bits. See attached images!

Hi, thanks for posting. How do you compare the exr and png? Are they any different in VFB? Where did you get the above screengrabs from (is it Adobe Photoshop for example)? There could be slight differences that are expected because different viewers may use a different colour space (for example sRGB and Gamma 2.2). Please read more on this here.
