Deniz,

what magic potion do you add to your rodinal? I used 1:25 once and kept the negs in the darkroom for years as they made a nice alignment-test. If this big, well defined grain was sharp corner to corner in the focusser as well as on the test-strips, I could be sure everything was within spec.
