I use an Epson VM750 to scan my 4x5 transparencies for subsequent processing in Photoshop Elements. I don't use the Silverfast software that came with the scanner.
As you know, the Epson scanner software provides a number of image adjustments that duplicate those in Photoshop (unsharp mask, curves, levels, etc), as well as an "automatic" exposure adjustment. I have the scanner set to output at TIFF.
My question is, what is the optimum strategy for handling the image adjustments? Do them all in Photoshop, or try to get the image "close to" correct in the scanner preview, and then do the final tune-ups in Elements? I've been getting reasonably good results from doing a rough levels adjustment in the scanner with sharpening set to low, and then doing the fine adjustments in Photoshop. I'm just wondering if that's the best way to go about it. Naturally, the documentation for the scanner and PSE doesn't provide any guidance on how their respective adjustments interact.
Thanks for any advice you may have on this.
