Hey all, I have a Canon EOS 20d and I took a CD rom into Costco to have some 5X7 prints done and I also took the CDROM into Target to get some 4X7's printed. The exact same prints. I chose Costco becasue the overall cost per print on 5X7's in cheap. I chose Target on the 4X6's becasue I had a coupon for (48.) FREE prints. The Lustre Costco prints came out pretty good but the glossy Target prints are horrible. My questions to you all is, what should I look for in a print lab for the BEST quality prints? What are the differences of GLOSSY, LUSTRE and MATTE???
