Brightness and gamma control in XnView 2.05

[GrahamM]

When looking at HDRIs, many images can be unrecognisable without adjusting brightness/gamma.
Is it possible to change brightness/gamma in the thumbnail tab view in XnViewer?

I’ve tried playing with Options > Browser > Thumbnails > Use Gamma correction,
to find a gamma level that better suits most of my HDRI’s but this setting doesn’t seem to affect the thumbnails or previews (even tried removing thumbnail cache)

Thanks
Graham

Hmm, I just tried with XnView 2.00 and it worked fine.

I've set gamma value in Options > Browser > Thumbnails > Use Gamma correction and then used View > Rebuild thumbnails to rebuild all the thumbnails in the current folder.

Thanks Helmut,

It seems to be working now!
Rebuilding thumbnails does the trick!!
