I do a lot of scanning of both film and art. Does it make any sense to make corrections (color,, exposure, etc) using the scanning software? Or should I save that for Photoshop? Thanks.
Here are a few reasons why you might want to use your scanner software to do some basic corrections.
Save time. By making your initial color and exposure adjustments during the scanning process, you'll get the job done without adding any time to the project. The scan will take the same amount of time (minus the initial setup) and you won't have to do so much work in Photoshop.
Take advantage of higher bit depth. Some scanners can only output 8-bit files. However, many of these same models can input files at a higher bit depth such as 36 or 48-bit (refer to your scanners documentation). If you use the scanner software to make adjustments, you can also take advantage of the higher bit depth file and produce higher quality scans.
On the other hand: My own experience has shown that some things are better left to Photoshop. Sharpening is one of them. Why? I don't know. I just feel more comfortable with Unsharp Masking, and the new CS2 contribution, Smart Sharpen.
