From: "Austin Franklin" <[EMAIL PROTECTED]> >>>>>>>>>>>>> At this stage, you don't expand anything. You set your setpoint so that you only USE the valid image data within the overall range. Therefore, say, your scanner is 10 bits, and therefore gives you 0-1023...and your image data occupies the range of data from 233-876, you set your setpoints at 233 and 876, and take THAT data and "remap" it to 8 bits. In this case, it is a decimation, and it is rarely an interpolation, since the valid data region is almost always more than 8 bits. <<<<<<<<<<<<<<<<
I understand that that's the theory, but when I scan negatives on my Nikon 8000 with NikonScan, it clips either the lows, highs, or both. It gets the black point increadibly wrong, but that I can deal with. Do you (or anyone) know how to persuade NikonScan to distribute the range of values from the scan within it's actual range without clipping? Once I have that, I could scan at 14 bits, 4x or 8x, and set black/white points and futz with curves in PS (well, PWP) later. Sigh. David J.
