1) No, you should not need to use RAW files, thought RAW does give more to work with. I have not used that program, so it is possible it may have a limitation. I have done it with Tiff's andf JPEG's, in Photomatix.
2)No, you should be able to use separate adjustments of the same image. Some software needs to be tricked into taking them, as it may look at the exif data and see the same exposure values for all of them in the exif.
Again, I am not sure how that program handles it, but generally speaking, that should work. Though I have not used it, I think I may have that program installed at home and I can give it a try this evening if needed. |
