I have EXR file and when I convert it to TIFF via Photoshop then RawTherapee opens it correctly.
When I convert EXR file by open libraries ImageMagick or FreeImage to TIFF, then RawTherapee shows images with red nuance.
Photoshop file: https://drive.google.com/open?id=18kXR5oSpo6Qcvcgm63WWEiOd2VkH-QYP
FreeImage file: https://drive.google.com/open?id=18om5GMYD50rutAUBzONxOOp8SLaAPQcs
And in RawTherapee:
Does anyone have an idea where problem is?
Your FreeImage TIFF file has no assigned color space, while your Photoshop file does (sRGB).
Either assign the correct color space ICC file during conversion, or assign the correct input profile in RawTherapee’s Color Management tool.
Thank you for your answer, but I am wondering why some other programs can open it correctly.
I am also not sure which color profile to choose.
Also here is ImageMagick file with sRGB : https://drive.google.com/open?id=1FHTyHAf9exIlwaseq686a4iOarPzWcVo
And without color profile RawTherapee shows it little red, and with embedded color profile it is quite dark.
They assume it’s in sRGB.
Generate a profile with sRGB primaries and a linear gamma (tone response curve = linear_g1.0):

Thank you very much Morgan, it works with newly created profile
