Thanks for the courtesy, John, but, I'm going to bow out of this discussion. 

The reason is that several weeks ago, the detail level of the questions and the amount of my time required to generally guide him and answer his questions in the level of detail that he wants told me that I crossed the line from teaching (which is what we do enthusiastically on this forum) to doing free consulting for someone whose practice will likely profit from that consulting.  In addition, I don't believe his basic approach (ie, PS vs a real programming language) is correct, nor, as you just pointed out, the lack of emphasis given to the image lighting and capture issues, not just the image analysis aspects (which I pointed out to him quite some time ago).

Best regards,

Tom M
