I would like some advice, please, on how to balance all the tradeoffs when shooting a group indoors.
- The scene: 8 high school girls dressed up for homecoming dance.
- The victim: Dad, trying to get the best indoor shots of the group
- The equipment: Canon EOS Rebel T2i, 18-135mm f/3.5-5.6 USM IS lens, Speedlite 580EXII with diffuser
- The settings: Av mode, f/11, ISO 400, 1/60sec (Custom setting for shutter speed in Av with flash = 1/60 to 1/200)
I wasn't that happy with the results. Everyone was in focus, but exposure was just OK and needed tweaking on computer. Sometimes not enough detail in shadows, like a black dress. (Couldn't move group and they were in a narrow alcove with glossy white paint on walls and ceilings.)
How do you balance these tradeoffs?
- Shutter speed needs to be faster than 1/30 to avoid camera shake
- ISO must be kept low to avoid noise
- Aperture must be f/8 or narrower to keep everyone in focus
- Want as much ambient light as possible to avoid flash glare
That last one is a new revelation of mine. I believe that when shooting in Av, the T2i tries to meter for the background. So maybe adjusting so more ambient light can get in would be a good idea. Maybe because I have an IS lens I could go to 1/30.
Any advice would be welcome.
