Bellows factor

[Don7x17]

The 'inch method' of lens and bellows length is a lot simpler than those hand held computers and all the math formulas. Quick and easy. Even more so if you use a level that has a tape measure.

Even better -- go to a cloth supply store. Buy one of those fiberglas yard long measuring tapes....sew onto the edge of your darkcloth. you'll always have it available and no fumbling around looking for it when you are in a hurry.
