I am at Cocoa Beach FL, just got here. We already went around looking for spots and I took a few pictures to see how close I can get with 250mm, which looks pethetic (if only a 2x teleconverter fit my lens ).
I still want to try to get some pictures so I was wondering if I should use a polarizing filteror a UV filter? I was reading about taking pictures and once its in the air i need FAST shutter speeds. Here is a quick sample of what I'm talking about.... ISO 100 6.3 1/2500 UV filter 
ISO 100 6.3 1/2500 Polarizing filter 
ISO 100 6.3 1/12500 UV filter 
ISO 100 6.3 1/1250 Polarizing filter 
View at where we are thinking of going... I need to really play with settings ISO 100 9/0 1/400 UV filter - VERY HAZY. I dont think it will be hazy at 8:56am when its supposed to go up. We are thinking about leaving around 12-2am to get a good spot. Which means we will be there for the sunrise and I'm thinking the sunrise might be behind the launch pad, any recomendations for setings for that?

The last one I was at, I was at 1/1600, f/5.6, ISO100, 400mm (crop sensor) That was 2:20 PM. I would shoot for at least 3x or 4x your focal length, a wide aperture, and expose for the sky about 10-15 minutes before launch. I dont see a need for a polarizing filter, I dont think it will make that much of a difference and you need the extra light. Your T1i should have decent ISO performance, you should be able to go to ISO400 without problem. I do like your exposure that is 1/1250, f/6.3 ISO100. Possibly play with ISO200 and adjust shutter to compensate. But for your focal length I think 1/1250 will work well. I am not sure about sun position. There might be some sort of calculator out there that shows sun position for your location and date/time. |
