HDR Versus EXR diferent colors

[Whitemagus]

Hi,

When I create the panorama the HDR is giving me a diferent color then the EXR and tiff.

The HDR gives a much more purple sky unatural look. 

Is this normal? do I need to change to diferent clor profile?

Hi,

The HDR format is not color managed, the colors are up to the
application's interpretation. Most likely Photoshop is assuming linear sRGB.

The .hdr format also suffers from compression artifacts, so it's better
to use .exr.

Kind regards,

ok, thanks,

The problem is that some render engines only accept HDR, but I will do both.

You could try setting the Output Color Space (HDR) to Linear sRGB. This
is probably how your render engine will interpret the file.
