Repeat until you are at infinity, say.

Assuming I manage to cut through the math and create a similar scale, or simply copy yours, I am still a bit confused about the sequencing the focus spots. You mention that you followed the C of 20 and focused in four steps . What exactly am I supposed to align and where? If I stop at the closest distance, do I take that to 20? Then where? How can that progress to infinity? I am very curious about the mechanics of focusing.<br /><br />Thank you.Kept Lighthttps://www.blogger.com/profile/11210117334068006044noreply@blogger.com
