Hi, I shoot RAW with a Nikon D300. For an upcoming show at a very small local gallery, I'm submitting five images. My question is, what do I need to know about making 16x24 inch prints? Pixels per inch? Do I re-size them in Photoshop, save them to a .jpg and then have them printed? I've never made a print larger than 8x10 and even then, it was done at Target. Right now, I'm planning on having the prints made by MPix.com, but am open to suggestions there. I will be calling local photography shops as well to compare pricing. Thanks Folks!
