- I've witnessed and photographed shuttle launches from the press site
- (about 3 miles away). At that distance you can feel the ground
- rumble. You can feel the heat of the exhaust on your chest (on a hot
- day at that). It is one impressive event. I'd say its the most
- exciting thing you can watch in public. Get to within a mile?
- No thanks.

- A semiprofessional's recommendations (I've photographed 3 shuttle
- launches and sold both prints and pictures to magazines of launches as
- well as much other stuff):
-
- At 3 miles I got excellent results with a Canon A-1, a Canon 500 mm
- and a matched Canon 2X teleconverter. The effective f/stop was f/16.
-
- Films used were Ektachrome 64. On a bright sunny day I shot at both
- 1/500 second and 1/250 second. 1/500 gave really good image of the
- exhausts (both liquid and solid). 1/250 gave better over all balance.
-
- If I ever get a chance again, I'd likely opt for Ektar 125 (1 stop
- gain) and shoot at 1/500. That would overexpose the flames, but a
- good to excellent lab might well be able to bring them out in custom
- prints.
-
- Of course I used a solid tripod and _no_ exposure automation.
