Maybe you read about projected image, CRT or possibly LCD? If the image is presented with greater dynamic range, you'll need more bits to cover the range. Also, you'll have more fine step discrimination if the image is brighter, like in the case of slides, especially in dark areas. The dynamic range of prints is not as wide... and this is especially true of processes with lower Dmax. However, in order to fully utilize the 7 to 9 bits of level resolution at the output, you'll need to edit images at a significantly higher level resolution, as customarily done by many people here by selecting 16 bit mode in Photoshop. How many extra bits are necessary depends on what manipulation is given, but 15 bits are enough. -- Ryuji Suzuki "People seldom do what they believe in. They do what is convenient, then repent."
