A VueScan raw file is different from a DSLR raw file. It's essentially a linear gamma RGB TIFF file without VueScan's image processing applied, and is designed specifically to allow multiple different adjustment settings to be tried with VueScan without having to run the media back through the scanner. DSLR raw files have quite a bit more flexibility in terms of what you can do with them. The negative side of DSLR capture is that you're dependent upon the quality of the optics, how well you focus them, and of course limited by whatever resolution the DSLR is capable of. However, with today's 10-14 Mpixel DSLRs and a suitable setup, you can achieve approximately the same image resolution as a 4000 ppi scanner with better dmax from 35mm film. -- Godfrey godfreydigiorgi.posterous.com -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
