Sorry for double post. I couldn\'t add a comment to my first report.

I used Mantiuk \'06 to tonemap a small selected region of a HDR (at full resolution) and found out that the resulting image is different to what I get when I tonemap the whole image at full resolution.

Examples:

Look at the trees in the foreground. They are darker in the image of the detail view.

  • Same here. Just changing Result Size while tone mapping above 1536x1357 -> gamma goes apeshit (and perhaps saturation - hard to tell what goes on there). Can post examples if needed. Happens with Fattal
