I recently bought a latching cable thinger for my 35mm SLR and finally decided to try some night photography on the 4th. All I had on-hand was some ISO200 film but things turned out pretty cool (after doing some color correction). I wasn't really doing much planning, just point the camera where people were setting stuff off in the valley and then hold the shutter open for a while and see what happened. I thought about using a polarizer to try and maybe cut down on some of the haze but didn't use it since I'd never tried anything like this before.
