HDR color management

Postby arabtornado » Mon Jun 25, 2012 1:48 pm

I have a 32bit hdr photo i opened it on Xnview MP but it appear dark and under exposed because it's not gamma encoded, but when i open it on Photoshop it looks good, i adjusted the ICC settings on XnviewMP and changed the default photo profile to sRGB and the profile file is "sRGB Color Space Profile.icm" and that doesn't solve the problem and the image still looks under exposed. Anyway to solve this problem?

Do you have tried to change gamma setting for HDRI?

I changed the Gamma setting from "Enhance Colors" but i couldn't reach the same color tone on Photoshop and even if i can, what i was asking for that Photoshop automatically adjust the exposure of the HDR images to preview it correctly, and i think that it's not about the gamma setting... it's about Exposure setting and color profile which i think Xnview MP doesn't has.

Wow! Such a big difference between XnView and Imagine :( (both default settings)

+100, already requested - (a false HDR mode) ;-)

A kind of custom retinex algorithm (for all xnview's products):

Can't get XNViewMP to display my rendered HDR correctly, they look overexposed.
While when viewing them with regular XNView they look okay
