Subject: Re: Exposure to the right and tone placement



Steve,

Your comments on the compressed NEF format are most interesting and I am not certain how to interpret the significance of this compression. Since, as you say, it is visually lossless, I suppose it is not a bad thing. According to the Weber-Fechner law our eyes can perceive only about 70 tones in the 2048-4095 range, we don't really need all 2048 of those tones, most of which are wasted as I mentioned in en earlier post on this forum; 161 tones should be sufficient.

I would appreciate your insight with regard to the practical effect of this compression as well as any references for further reading.

Bill
