"Yes you can just bump up the contrast of an image to make it appear *like* an hdr, but you will not get the added effect of it actually casting light into the scene, so you'll only see the effect if you have lots of reflected objects."

Indeed. Here's my first attempt. Like you said, not true HDR, but HDR cannot be achieved correctly in Bryce, so it's all fake anyways. Top is original render, bottom is with postprocessing. I used both the "blooming" method I described above, and a sort of "reverse blooming", in which I took the darks instead of the lights and used burn for the layer combinations. This effectively increased the contrast in the image without losing much if any detail. It's a pretty subtle difference; I should play around with it a bit more.
