[Leica] Exposure and Development

[luisripoll at telefonica.net (Luis Ripoll)]

Hi Mark,

I'm very happy to see that I'm more than 100 years old (and still in form).
I've never used multicontrast papers..., but I agree with with your
absolutely correct comments!

Saludos cordiales
Luis

Its THE general rule for a long time before Smith and its the basic rule for
how film works. That's how you figure out if your film is getting the right
amount of development and exposure in general.

But as most rules are meant to be broken it can drum up some controversy.
As it may be the way film works but its not the way you as the photographer
work in the practical sense.
In practical shooting you end up working with negative black and white
materials very much the way you work with positive transparency materials.

You expose for the highlights.
Let the shadows fall where they may.
Then get out fast.

Sure if you had time you could take shadow readings and see where they are
gonna fall and worry about if you're going to worry about it but if you try
to control your highlight placement through development after exposing for
your shadows you are in for some real trouble. Yep that's how film works.
Even sheet film shooters end up just running pretty much all their separate
sheets in the same soup for the same time just like their roll film pals.
"Contrast" gets controlled later with this new invention they came up with a
hundred years ago called graded contrast papers. The ones with the numbers
on them? Then 50 years ago came multi contrast papers with filters.

You see those shooters, like bird watchers and nature lovers running around
in packs with spot meters - what are they aiming at? Up! The highlights in
the leaves of the trees that's what it all comes down from that reading.
Highlights need to be placed through exposure. Not development.
In practical practice. Though its not the way film really "works".

Otherwise your shots won't be properly scintillating.
And you'd not not want that.

Those little highlights have to be right on the money.

Scintillation is everything.
And you can quote me as I just made that up.
