UMMM!!! Sorry, but in aerial work, you often want all the contrast you
can get (unless you can fly lower than is legal under many circumstances,
or the day is clearer than virtually all around here...). You also want
SPEED, since even 1/500th second shutter speed seems inadequate as you
bounce around up there. Velvia would be great, but its speed makes it
useful with short lenses only (with obvious disadvantages...). I like
Kodachrome 200, though Sensia 100 pushed a stop should be nice for
this purpose. Camera simplicity is a MUST in the air, which for me
means 35mm (and it is one of the VERY few times that I consider using
auto exposure - but AF is a no-no [better to lock in the near-infinity
focus, or touch up focus as best you can manually {while bouncing around,
and being buffeted by the wind...} - relatively wide apertures are
desireable to maximize shutter speed, and focus MUST be right {everything
is at one distance, revealing errors rather too clearly...}]). A skylight
filter can be useful to counter distance bluishness, but NO filter will
reduce haze with standard films and most lenses...
Hope This Helps
