Unfortunately, Tom, you're incorrect here. The "analog" output from that sensor is still quantized into discrete steps (either the number of electrons in the well, or the number of photons that hit the sensor - take your pick). Both of those numbers are below 2^17 (around 128000). So you're never going to get more than that many different values in your digital output. (Or in your "analog" input curve, either, if you look closely). -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
