i usually shot portraits with my 60D and tamron 17-50mm f2.8 using maximum resolution JPEG + RAW @ 5184 x 3456 pixels. after recent photoshoot, i tried to print an 8R using this particular setting and the result were dissapointing in my case (lack of details, seems stretched etc..) i wonder what is the proper way to print a large picture over 16x20" and 20x30"?
thanks
