Thank you for your reply Bart.

What I was referring to by animosity was the sudden turn to accusation of bias, fraud, ignorance. This in spite of the fact the description of the method specifically mentions the aspects of lighting and limitations of the equipment. Ignorant statements about how the appearance of scratches can be manipulated to appear smooth or deeply furrowed, combined with assurance that these cannot be 30k because they are too coarse in appearance is far less than I expect from an intelligent conversation.

This kind of response, and I have seen it before. Along with the mindless buddy system of thanking up the rep, like some middle school popularity contest truly makes me question my participation here.
