So here's the deal- I've run a summer camp for 10 years. I thought it would be cool to put some old pictures up on board this summer. I ended up with a 6' X 4' collage which I had laminated. Now I would like to make regular poster sized prints to give to families. From what I've found, the best bet is to take a few photos and piece them together to make a picture that can be blown up and retain a sharp look. Having just started, it seems my first hurdle is going to be finding a way to gets shots without a ridiculous amount of glare. Would someone mind steering me in the right direction?
