The M with much greater processing power has not used this option. > Geoff... if it is either 8 bits or 14 bits, and you then process the > image in LR or CS, what data is LR or CS working with? 8 bits, or > during file opening, the data is decompressed from 8 bits back up to > 14 bits and then you are working with 14 bit data? > > The issue to me is the quantization level achievable in the post > processing..... > > Frank Filippone > Red735i at verizon.net > > > Brian, anecdotally most M9 shooters use that compressed option, > although I didn't personally.
