Hmmm, aerial work is a constant battle with bumps, haze, speed,
changing light, and distance. You don't have time to fiddle
with polarizers, etc. A skylight filter may help with slide film.
Use the fastest film you can that will still provide the quality
of image you want (K-200 and Kodak and Fuji E-6 100 speed films
pushed one stop should work well for slide film - negative film
simplifies things a WHOLE lot!). Lenses from 35mm to about 105mm
(f2.8 or faster primes) work well, if sharp at infinity focus to
the corners at wide apertures. A gyro-stabilizer (expensive, and
I have one for sale...;-) can help with bumpy air, like what we
have around here. No overall exposure compensations are necessary,
but exposure is a problem (it is the only time that I use auto
exposure, and accept the resultant lower percentage of good
exposures [there is not enough time to keep up with the change
in light with angle as the plane changes direction using manual
exposure mode in sunlight]). It's interesting work, but someone's
gotta do it. ;-)
Hope This Helps
