Soon i will be doing a set of engagment photo's. This couple would very much so like me to blow it up fairly big, and mat it so their guest can sign around the photograph. The last time i tried this, the print came out horrible. Of course that was with a sony cybershot, i now use the canon xt. Im not sure if i possible shot it in the wrong format, or the printing place was so-so. This are personal friends of mine who are looking to giving me experience. any suggestions, or maybe i should be asking any good printing places. I live in florida..
