I volunteer at a local hospital and have been asked to take some pictures of patients in hospital at an awkward time of year. The will be able to move to wheel chair against some wall with Christmas decorations. I freeze up with people and don't do well but still would like to help them out.
I have two flashes Canon 580Ex and 430Ex speedlite, I have a home made bounce diffuser: http://super.nova.org/DPR/DIY01/
Lenses: 17-55, 100 macro, 70-200
Tripod and remote switch will be used.
I don't know which lens is best and how far away I can get.
I don't know how to point the flashes to get best effect.
Making people comfortable and posing them is another art I don't think there is time for here.
Any assistance would be much appreciated.
