Well, John, it's time for another aspirin .... too many graphs and charts and logs of this and that. However, one paragraph stood out amongst all the techo talk:
"Before I go any further I should point out that this test is only going to produce a theoretical result. Since I am testing film, the dynamic range that I will be calculating will be much higher than any figure normally quoted for film because very small changes will be detected. At some point these changes will become irrelevant to the appearance of the image but since this is a subjective judgement I'm going to leave it at the calculated value for now. I'll return to the subjective arguments later." Shel > From: J. C.
