It is not just washed out; the suggestion to reduce it's RGB values will not work because logarithmic appears to be performing a curves adjustment on the RGB values, in effect solarizing the image. How in the world can I place a bitmap image in a radiosity solution that will look correct? I'VE TRIED EVEYTHING!
I've gotten hints from other newsgroups that placing bitmaps (full ones meant to be seen as an image, not as a texture) in radiosity solutions is actually something that you just can't do in Viz 4. Is this true? I can't believe it....
Thanks in advance!

i had the same issue. logarithmic exposure control works very well when the overall solution is roughly on target(turn off all exposure controls). i had some luck when i was turning shininess down to 0 and gave the diffuse and ambient colors a full black. you could change the texture after calculating the radiosity. copy the bitmap to the self-illumination channel if you need it to look closer to the original image.
good luck!
