Recently I shot photos for my church's vacation bible school, I've been asked to shoot photos of the upcoming youth rally, and I need some help. I have a Canon Eos dslr with a 17-200../3.5-5.6 lens. Built in flash only. I learned some things just from my vbs experience, like the ability to adjust the WB and tricks to eliminate camera shake. However, I hate shooting in the main room where the event spends most of the time. It is a large room, much like a social hall, the lighting can vary according to what is going on (music worship, the stage lights are on but the audience is dark...this drives me nuts) and I'd love some tips if you have any! I am thinking of getting a speedllight flash...although I'm not sure how great it will be in a room so large I have trouble bouncing it off anything. I used the built in flash last time, but either it is too strong because i am to close, or it's worthless because I am to far away...it was hard to gauge the ideal distance. I was also wanting to get a faster lens...I was looking at the 50mm/1.8 as I see this is great for indoors, but I also understand if at 1.8 the DOF will be minimal. With my 17-200 I set a low ap depending on FL and pumped up the ISO to 800 or 1600 in some cases. Would I benefit from one of these items, or any tips for making the best of my camera? I'm no professional photographer although I consider it a hobby and I really enjoy helping my church out here...I really want to do the best i can and learn as I go.
