    Great test! Need some higher-scale tests, you know black dog in shade of a tree in a park with the white dog in the sun. Brown dog can play Frisbee with a gray card. But still a great test (since you went to the trouble to do it) and proves its point.

    I never got to ask Todd-Zakia when they did the demonstration that 2-stops underexposed pretty much trashed your chances. Theirs was a guy in the sun in a suit with a white shirt and sunglasses, gray scale and gray card...

    These are the questions I could never ask them:

    Did you cut the film and develop the 800 longer and the 160 less? Did you go to great heroics to make the best possible prints? Was there any clear choice if you had to pick a favorite, did negs near 250 print the easiest? Any gleanings like that from this test?

    I get a kick out of the extremes of exposure placement that people expect will fall gracefully onto a given sheet of paper without burn and dodge. I'm more amazed a people's reluctance to apply a bit of flash to the black dog in the shade.

    The 2 under thing isn't a surprise though.

    Ok Bill, in order.

    The set of 10 I talked of above were all developed the same per Ilford's instruction sheet for EI 500, the target was normal contrast, only exposure was varied.

    No great heroics on this set.

    I use a Beseler PM2L to set enlarger exposure, the challenge is mostly in finding the right point on the negatives to peg to. The PM2L has the same issues as any meter does in the field, one must properly judge what is being measured. (For those that don't know the PM2L and it's kin are basically spot meters for the enlarger.) Once I found the right point to peg to the negatives were equally easy to print. All done at grade 2.
