Premium Member David Mullen ASC Posted February 23, 2010 Author Premium Member Share Posted February 23, 2010 There's a stain, I think. I'm looking at the pronounced vertical lines in the greyscale; is that really just a wear and tear issue? P Like I said, the chart has seen better days... I wouldn't try to make judgments about pattern noise from it. It had a slight texture to the printing. What's a good test for pattern noise? A grey scale full-frame shot out of focus?
