Thanks all for the comforting responses to this. I have received info from Bob and others on private e-mail about this interesting option of adding noise, not blur, to potentially help some file.Actually the addition of noise has become a common way to make digital files from camera look more like film. Problem is that the more one gets into this, the more you have to get in. Now that I know what kind of goofy treatment my files may get in the wrong hands, then I assume I will have to spend more time on the computer, and most likely, end up running my own cmyk conversions. As this is going to be a step by step thing, I will start by coming back later in the week as soon as I confirm some interesting research I have been doing with the GretagMacbeth color chart and a simple method of internal calibration( not profiling) for digital cameras and some interesting re-discoveries about the chart.
