Lightmix COLOR SPACE

[LeSill]

Hello, guys.
I've rendered several cameras from a single project. Each camera captured roughly 50 frames. I've rendered passes, including lightmix. When I open the lightmix pass in Photoshop, it claims it was saved in LINEAR COLOR SPACE and prompts me to convert it to sRGB. I do not convert it and maintain the LINEAR COLOR SPACE. Somehow, it opens the image with "correct" colors, such as sRGB/gamma 2.2.
I'm not sure why, but now when I render a new animation, the lightmix pass is saved in LINEAR COLOR SPACE, therefore I have to convert it to sRGB.
What is the appropriate color space in which Cinema should save the LIGHTMIX PASS?
Best regards

I believe that linear is the correct space for compositing passes like lightmix.
I would generally use the corona image editor for creating new versions - but I'm a stills guy. Photoshop has some shortcomings working with exr/32 bit files and its best to edit elsewhere.
If animating you'd be better off in nuke or AE which can edit the .exr pass layers in linear - and output srgb or whatever at the final stage.
