Eric Praetzel Vacation Pictures - Carlsbad Caverns NP

 It was nice to finally be in a cave where they let you use tripods. I was also visiting during a very quiet time and so I could easily setup the camera and do timed exposures. Other people had limited luck with flash cameras [only formations from 1 to 3 meters/yards are visible] and I saw several people have some reasonable success using low-light, low resolution, video cameras. Most people with digital cameras were using a flash and so not getting much depth.

These pictures were taken using timed exposures. 100 ASA Fuji film, F2.8 28mm lens, 20W halegon lamp [reduced since it was running on 11V not 12V].
Exposure times were 10 to 30 seconds based upon how I estimated the exposure.
Existing lighting is clearly visable. They say that they use not "colored" lamps; but they do use a mix of halegon, incandescent and flourscent as far as I can tell. They all have different colors.
The pictures are not as sharp as can be as the tripod did jiggle slightly.

I consider the pictures over-exposed. Cutting the exposure times by about 1/2 would be better.
