For example, scanners can only acquire the dynamic range of contrasty chromes when the acquisition bit depth is better than 10-12bits. The context with scanners is that the sensor is linear, leastwise not under software control, and 8bits can overlay only a part of the dynamic range. Once the image is acquired and RGB data is under software control, you can convert to 8bits, and you still have the same dynamic range, and Thomas' statement is true. hth & cheerios ... shAf :o) Avalon Peninsula, Newfoundland www.micro-investigations.com (in progress) =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
