Using a 1x1 JPEG is not very reliable because jpg uses lossy compression -- so some of the colors might not be exactly the same as the original.

I also use blender to display them like so: But that's cumbersome, so just to view I use exrdisplay.exe.

I have the PS plugin, but wanted something with the interactivity of hdrshop.

I need something simple like hdrshop to edit my exr files. All I really need is gamma and exposure controls. What do you guys use?

Here's another truly simple scene: a completely closed room with only one small opening. (Regular path-tracing could have so much trouble with scenes like this.) To test the MLT algorithm, I let it run for 25 hours. It still has some noise but the light-bounce and shadows are really nice and they lo...

Nice job -- It looks very, very real. 14 hours seems like overkill, though. Scenes like that don't really need MLT. A sun-light and amb-occ with a physical sky would make it look about the same and would take 1 minute. Of course, I'm not bashing Indigo or yor work. I just think that if you are doing...
