Fireworks photography

Fireworks are very nice photographic opportunities if you like shooting in the night. Unfortunately the fireworks where too fast and I didn't have enough time to keep track of all the exposures. I exposed Agfa ISO100 negative films using a 70-300 mm zoom lens between 200 and 300 mm opened at F/5.6. Exposure times were between 2 s and 1 min. The pictures were taken on August 1^st, 2005, and the city in the background is Neuchâtel (Switzerland) and was about 6 km away from my location, just across the lake.
