I'm planning to get some 8x10 pictures printed at a local shop. This will be my first time printing larger images from my files and I'm wondering what format is best to use. Some of my shots are large JPEG, which means I'm limited to large JPEG for printing (right?). However, most of them were shot RAW. Should I convert them to TIFF and take them to the shop? Or, should I convert them to highest quality JPEG? In general, what is the difference between TIFF and high res JPEG and when would you use one over the other? What format do you guys convert to when a shot is taken in RAW and you want to print it with top-notch quality? Thanks!
