whats up, not sure if this is the right place, but I've been shooting for some time now, and now I'm stepping into stuff on a much larger scale and I'm wondering if my camera can do it, I have the canon eos xt, and everything I shoot is at 72dpi, and I was wondering if thats the most that it can do, cause I really need around 300dpi or so, or do I need to step up my camera? if so will the 20D be able to do 300dpi?
