I shoot HS football under the lights for the first time tomorrow night with my flash. Previous after-dark football shots using available light have been fair, at best. I'll be shooting a D Rebel XT with a Sigma 120-300 f2.8 and a Canon 580EX flash (w or w/o a Stroboframe bracket)
- How do I do the custom function thing (you know, * focus and all) and still use the flash? C Fn has seemed to really hose up the flash and exposure in the past.
- Do I still shoot AI focus with the flash?
- How is the 580EX set up (details, please)?
- I presume I should shoot the camera on manual, right?
- What settings should I use on the flash (details, again, please)?
- Should I mount the flash on the hot shoe, or use the flash bracket?
- How do I adjust the manual settings to account for the flash?
- Do I use HSS on the flash, second curtain sync on the camera, etc.?
- If I employ my light meter, and use the reflected meter, should I point the meter at the field then use these settings on the camera?
- What else should I be concerned with?
- Other hints and/or pointers?
- Do I still shoot AI focus with the flash?
- Tell me anything I might not know (vast, I realize) that would help me out.
I'll also have my Canon 50 f1.8 with me, and might use this for wider shots, etc..
Thanks in advance!
