confuse us or to get help from us?

I'm sorry Hi_bud, never meant to confuse you.
I've should have titled it "different light conditions".
Indeed I was trying to make a point that pictures at magnification can be very ambiguous.
The same edge may look completely smooth or deeply scratched. All it takes is a minor adjustment of the lightng angle.
Actually I saw a thread last night were someone posted scratch patterns left by two different hones. I noticed how he placed the razors at a different angle under his scope (which has the same effect as altering the lighting angle). I wanted to illustrate how easy it is to jump wrong conclusions out of that, but decided to start a new thread, rather than offense someone that I respect, and know to have only good intentions with sharing those pictures.

My apologies for the confusion,
Bart.
