I'm going to be running some tests on Delta 100 in Rodinal over the weekend and I thought it might be an idea to glean some of your thoughts on the best way to evaluate a negative.

For my sample roll I'm planning on using the method that Les outlined in B&WP Issue 2 - picking a shot (probably a landscape, as I'm utter pants at still-lifes!) and shooting it on meter (almost certainly F80 matrix), +1, +2, -1, -2, until the roll's gone. Then splitting the roll in three and processing it on recommendation, +20% and -20%.

Can anyone suggest any variations on this method? I don't mind burning through a few rolls if I get the results at the end of it.

And, most importantly, what do you look for when comparing negs?

Thanks in advance,
