We do a lot of training of groups at work. I have been asked to take pictures during training sessions and a group picture at the end of the training. It is in a large conference room with about 70 people. Any advise on what settings to put my camera on when I take the indoor pictures, especially the group photos and when they are in session?
I am using a D5100 and have 18-55mm and 55-200mm lenses.
