One thing that I have found very useful for pictures of gliders is a
digital camera that can save images in RAW mode. Gliders are bright
white, and this makes it very diffucult to get a good exposure. The
glider may come out dull grey, or more likely it will be a completely
washed out white ghost, with no variations in shading to suggest its
shape. When saving images in JPEG, the image is not only compressed, it
is also reduced from 10 to 8 bits per pixel in the camera. This
effectively discards 2 stops of exposure latitude that you can use in
photoshop (or equiv.) to correct exposure problems, and give the glider
some shape.

Unfortunately the Kodak camera apparently only saves in JPEG mode. The
Olympus 5050/5060 and many others have a RAW mode that gives you a lot
more control over the image by saving the data exactly as it is
captured from the CCD imager, without irreversible processing in the
camera. This requires a lot more memory per shot, but Moore's law is
making that a non-issue.

I was browsing a CompUSA today and came across what looks like nearly
the perfect camera for taking photos from the cockpit. It's a Kodak
V570. 5 megapixel and a 23mm equivalent wide angle lens.

Here's a review:

The camera's tiny, the LCD is quite large and the wide angle lens is
about as wide as practical before going fisheye.
