So as some of you may know I am shooting for a local skate shop, they want pictures to go on their four windows adversting the skateshop and when its going to open and all that jazz. Im planing to take a picture of someone skating and photoshop coming soon on the picture but now to what i really need to know. One window is 6 feet wide by 8 feet tall, with my D80 10.2 mp camera how will it come out if i print a picture that big, will it look very grainy or will it come out crisp and clear if i print it out at kinkos lets say. Also they were talking about possably having one huge picture covering all four winds so thats 24 by 8 how would that come out? Thanks.
