Looks like DXO will export/save your modified RAW files, but only in Adobe DNG format. They aren't really clear about this on the official DXO web site but it's stated explicitly in Alan Briot's review http://beautiful-landscape.com/Thoughts35.html When the product was originally announced Michael Reichmann reviewed it and wrote: "DO Labs ... is working hard to complete a version of the program that will work with RAW files. This is a non-trivial problem, because the file would have to be delinerarized, de-mosaiced, processed, and then reconverted back to the camera's RAW format. But DO Labs says that they will be announcing a RAW version by Photokina in September, 2004." http://www.luminous-landscape.com/reviews/software/optics-pro.shtml As far as I can tell, the DNG export is as close as they ever came to implementing this. -- Mark Roberts Photography and writing www.robertstech.com
