What is the best software for HDR merging? I've noticed you can now merge photos inside of Camera RAW with decent results but I don't think the ultra-RAW image is 32 bit? Where as Photomatix and Merge pro in PS are both 32 bit. Also how many exposures should be used? Most people seem to use 3 but I've seen some using like 10+. HDR questions/answer here, would like to know how to take very good clean HDR photos which have made some of the best photo's I have seen, none of that over processed HDR crap.
