If you have a full frame camera, why not print a full frame image? Many inkjet paper sizes force you to crop to some degree. If you want to print a full frame image in all its glory you need one of Red River Paper's inkjet photo papers in these sizes. Each size has enough room to print an image that is in the 2:3 aspect ratio typical of a true 35mm sensor. Cameras like the Canon 1D MkIV, Nikon D800, Canon 5D, and so on feature a full frame sensor.
If you own a wide format printer like the Epson 3880, Epson 4900, or Canon iPF6300, take advantage of the 17x25 size to make beautiful and bold 16x24 prints.
