I'm currently using Elements 4 to process my digital images From my Maxxum 7D and 5400 II film scanner. I have been saving my money for SilverFast HDR Studio for my 48 bit raw scans from my 5400 II as you have recommended. Is Lightroom a viable alternative to HDR Studio for this purpose? There is a considerable price difference. I quite like the library/tagging feature of Album in Elements 4. Lightroom looks to be even better in that respect.
