Scanning formats (TIFF vs. JPEG)

Re: I think his point was "adjust quality factor so resulting image file has a size of ~10KB per sq in of original document". E.g., A size is ~90 sq in so target a 1MB file size. (note that this would correspond to an UNCOMPRESSED TIFF scanned at 300dpi! -- did I do the math right? -- in which case, the whole argument starts to fall apart since a 300dpi TIFF *compressed* would be much smaller! Or, for that given size, a COMPRESSED TIFF could be scanned at a much higher resolution) **************** You do understand what I was saying; unlike others, you understood that I was talking about resulting file size, not pixels. However, in the last paragraph, you missed one point, which was that my guideline of 5k to 10K per square inch was for color photographs. For monochrome, I cut that by 2/3, so my guideline becomes more like 1.5k to 3k per square inch. And this is very conservative, for files that will be, for all practical purposes, indistinguishable from the original. For many if not most uses, you can actually go a lot smaller.
