For me, the effect is only obtainable with rotation of 16-bit files. If I start with a new 5x7" 32-bit file at 360 ppi and RGB, then rotate and accept, and then convert to 16-bit, there is no patterning. But if I convert my 32-bit file to 16-bit, and then rotate, I get the same old patterned noise.
As I like to work with lots of shadow in 16-bit, this is a bit of a nuisance. I have not yet made a print to see if the gentlemen's suit patterns reproduce on paper.
