I will be taking prom pictures again this year for some high school students. Typically this happens in the evening so the lighting to me is difficult to work with. I did a shoot with some kids last year and their pictures turned out pretty well. Wondering what I could do or get for my camera that helps with the quality of the pictures. I am relatively new to taking pictures. I have a Canon Rebel T5. I will be working against the clock again this year to preserve that valuable lighting. How can I extend my picture taking time. Do I need a speedlight? a diffuser? should i be using flash? when i did it turned out too bright. any advice would be greatly appreciated.
