I've been following this thread and here's what I came up with.. I'm using P6 so no hdri but it does do ldri fairly well.  I took a photo taken with a powershot a520 and set it up in lightwave as whats similiar to a skydome. Setup a reflective sphere in font of the camera to get the mirrored ball effect. Lightwave has settings for hdr exposure as well as full precision gamma settings. You can save directly to hdr format.  This is just the ibl with ao.. ibl contrast set to 1.0 and intensity at 1.0  Notice the blue tint from the ldri.. I was having to set the diffuse at 127,127,127 also, but kept messing with the settings of the hdri and finally found a happy medium where I dont need to do so.

 I save as .tga format instead of jpeg.. Much better quality.

Handle every stressful situation like a dog.

If you can't eat it or play with it,

just pee on it and walk away. :-)
