I'm not sure. I'd have to see the tags in the TIFF file and the header for the BMP file. 4MB is a pretty big difference. Not big enough to explain a difference in 8-bit versus 12-bit (per component) color. Too big to be (easily) explained by "ancillary" information, like notes put in by the photographer, etc. > Is there a good reason not to save my scans in BMP rather than TIF? Well, there are a number of technical reasons, but if you're not distributing the images, probably not any practical ones. Technically, TIFF will be more widely supported and it supports a much larger variety of image types than BMP. For example, TIFF can easily handle 12-bit per component color and CMYK while BMP can't. TIFF readers might have trouble with it, but it's no problem to represent it in the TIFF data stream. TTYL, DougF - This message is from the Pentax-Discuss Mail List.
