About File Format for FumeFX

[Wasus]

For OpenEXR, some software will show different color then the original rendered image, washout or the orange will become yellow for exemple. I know that Photoshop, afterFX and Flipbook from softimage changes the color. I think that they intepret the footage as linear.

to fix this:

for photoshop:
In photoshop it will look washed out. To correct, create a New Adjustment Layer>Exposure and apply the inverse gamma correction of .4545
for afterFX:
on your footage, go to interpret footage and the drop down menu "Interpres As Linear Light" put it to none.

When you rendered something without any colormapping - its bringing your image to leaner colorspace and exr-format save all data in leaner colorspace (TIFF, TGA, PNG, JPG, etc - save data in SRGB). Otherwise, all monotors and viewers works in SRGB colorspace. And cause of this exr-files looks incorrect and others formats looks fine.
How you said, you can put your gama to 0.4545 (1/2.2) - looks good, yes, but more correctly issue to fix it - set up 3ds max LUT to gamma 2.2 (viewport gamma 2,2, input gamma 2,2, output gamma 1)
