Quick! Exposure/dev help for my medicated mind

mark · Sep 25, 2005

Since I am on some pills that scramble my thoughts I need some help.

Situation:
Taking shots of pine nuts and pine cones using APX and arista.edu. I am going to need serious contrast increase.

For increased contrast I expose less and process more? Or do I expose more and process more?

I know this is way rudimentary but I, for the life of me, can't get it straight in my head.

You expose less and process more. The EI of a film will increase as development increases.

Thanks donald.

Don`t expose very much less. I would not expose less at all, just more time in the developer.

I'm with Ron on this one -- reduced exposure shouldn't be any more than about 1/3 stop less, and Ansel actually recommended giving a bit more exposure (the idea, apparently, was to push the detail up off the toe so you didn't get big nonlinear contrast stretches that looked unnatural). OTOH, Ansel seems to have recommended more exposure for every situation -- "if in doubt, give another half stop or so".

That's about the only thing Adams and Mortensen ever agreed on - and the advice is exellent.

Yup, you can almost always salvage an overexposed neg, but it's pretty hard to do much with a seriously underexposed one.
