Yup, what we gain with "thinner" emulsions and use of sensitizing dyes is increased sharpness and resistance to halation. Not a bad tradeoff.

But sometimes we may want that old school look.

I hear some folks say older style emulsions are friendlier to their ventures with pyro and staining/tanning developers. Mebbe so. I haven't tried 'em, unless it was in school 30+ years ago and forgot.
