Thanks for replies. Markus, they are all elongated in the same direction. I shouldn’t have said “perfectly round” on the right, but rather, “less elongated”. But all elongations are in the same direction and more pronounced after dither. I don’t think settle time after dither is possible but would love to be corrected. All subs are the same length, so I don’t yet know if exposure length makes a difference. As for dither pattern, I don’t know. I just click “dither”
