A purist acceptable version of the double printing
technique is to make two negs without moving the
camera from the tripod. Make the first one with the
filtration/exposure to suit the foreground and the
second with the filtration/exposure to suit the sky.
When printing make the main exposure from the first
neg and then put the paper away while you change negs,
then use the second neg to burn in the sky. Make sure
the horizon, hills, trees, etc are fully dodged when
making the second exposure because the registration
won't be perfect - clouds are usually fluffy enough
for this not to matter. All the other mentioned
techniques (red filters, polarizers, increased paper
contrast for the burning in, etc) can be used in
conjunction with this.
I think a lot of 19th century photographers did this. Interestingly,
in the most recent issue of the Sierra Club magazine, there's a series
of color photographs of the Sierras where the photographer did this in
Photoshop. She makes two or more exposures and then combines them in
Photoshop. Because she is using color transparency film, there is less
latitude for expanding and contracting the range of the film. This was
interesting to me because I have wondered what to do about this problem
when using color transparency film, which is my other love after b and
w film.
The pictures looked a little other-worldly, but very beautiful.
If you're working with long exposure times on a tripod
(more than a second) you can also _dodge_ the sky when
making the camera exposure. Just use a matt black
piece of card and wave it around in front of the lens
for roughly three quarters of the exposure (only half
if you are using a yellow or orange filter as well).
You have to judge where the horizon is relative to the
lens and wave it from there upwards a bit and back
down in a vaguely random and unceasing kind of way.
If you are being really careful you may want to use a
second piece of card to flag the dodging card and
prevent the sun from striking the edge of it which may
flare.
!!! Amazing idea!!
