I am shooting Santa pictures at school on Saturday for a school event. I've done this before with a Minolta Maxxum 7D and film using The Shell attached to my flash as a reflector to minimize red eyes and it left minimal shadows. I've recently bought the Sony A100 and F56 flash unit which is way more advanced than my last flash. I'll be using the Sony gear this weekend since film is not economical for this. My first flash question is what batteries do you all recommend for fast recycle times?...I don't know if my rechargeable NiMH are too old or tired but they don't seem to always keep up with the camera. Secondly, the pictures will be in the school cafeteria with a dark green backdrop, should I keep the flash camera mounted and bounce off the ceiling or attach The Shell for bounce or should I set it up off to the side using the on camera flash to fire it...I have large pieces of white foam board I can use as reflectors too. I just don't want problems with bad shadows since Santa will be closer to the backdrop and I don't have studio lighting yet. I want these to look great even though I'm not making any profit since this will be my first job in this area...we moved this summer to a new state and I'm hoping to get people interested in hiring me. And due to volume and no profit, I am not willing to photoshop post facto on these shots. Thanks for any help.
