hdri problem

[mahsa_311]

hi all I have problem with hdri in my pd player.
when I open it in pd player (in default ) I saw it lighter than when I change to srgb mood
and I don't know which one is correct please help me to find it

Chances are you don't need to gamma correct a 32bit image. (Unless maybe it was computer generated.) So, inverse gamma should be fine with a small tweak or two the gamma value until you're happy.

thank you for attention this. your theory is correct but we take different result when do this in vray .it`s different in thumbnail and pd player(and vray hdri)

Can you show us some examples and perhaps sending us a demo-scene including HDRI file?
Most likely the HDRI is loaded with different gamma-settings but we need some examples to find out what's going on.
