ok so i am a senior at my high school. through my previous years i have walked past this door with some "funny lookin" man on it on my way to gym. well this door just so happens to be the door to the photography room of my school. i now take this class, turns out this guy on the door is charles chaplin which a former student had painted on the door for my teacher. and as a first year student my teacher has asked me to come up with something she can put on the dark room door. she didnt ask a second year "advanced photography" student, she asked me. so basically i was wondering if i would be able to print something of that size and it still be clear and crisp. i shoot with an xti in raw. i will of course try and shoot with the lowest iso possiable and try to crop as little as possiable, if any. can it be done? any tips?
