He means MB. 16bit scans for me are around 20MB for B&W or 62MB for colour. My MF scans are more like 140MB each. -Adam >>Now, here's another hidden space saver: When processing a RAW file, I can >>make numerous changes to the image - color balance, contrast, hue, >>saturation, and so on, all without increasing the file size, and all with >>being able to save the original file as well as the changes using the >>Photoshop raw converter.
