I mainly shoot ambient but our league has several dark gyms. I use a 50D and am happy with images up to ISO 3200. I shot this at one of the darker gyms and was hoping for some insight on how to improve my technique. Working towards AB800 or Einsteins but this is what I have now.
I used three speedlites (580EX and two YN-560's) with RF-603's. The 580 was mounted on the far side of the court bounced off the ceiling, the 560's were mounted on the shooting side (my side). One was aimed for ceiling bounce and the other aimed at the end wall to bounce.
Camera settings: ISO 640, f/3.2, 1/200
Flash settings: Manual, 1/2 power, zoom at 80mm for end wall bounce; 105mm for ceiling bounce.
Makes it easy to switch between two different setups by turning the knob.
Although this one doesn't look bad at this size and would be OK for newsprint, most of my ISO 6400 files are bit disappointing as 8x10 prints. Direct flash is a huge difference but I've been trying to bounce as I like that look better.
