My brother is a part-time fire fighter and his department is dues to have a big group photo taken, they asked if anyone knew anyone they trusted to do it right the first time and I got volunteered. I was feeling good about it, I had to change there original plan slightly because they wanted to shoot infront of a fire hall in the morning when the sun would have been behind them, I moved them out on the lawn, so I should have the light over my right shoulder. I had planned on using my XT and my A-1 on back-up, but just yesterday I was informed they want to enlarge this to something like 18"x24", will my camera do that? specifically, has anyone used a 8mpix XT with the 18-55 lense on it the shoot and enlarge that big? Will my A-1 allow me to go that large? Id find some premo film and probubly use my fast fifty on a tripod ofcourse. I dont have any medium format stuff..... yet, so this is what I have to work with. Is it do-able?
