what kind of paper is used for photos
Kodak Professional Endura Premier Paper (Traditional E-Surface Paper) is the most popular paper used by professional photographers. Accurate color, realistic saturation, excellent neutral flesh reproduction, and greater intensity are just a few of the benefits of E-Surface paper.
Swellable paper is designed for high-quality photo printing--the coated surface actually swells as it absorbs ink. Cotton rag is ideal for inkjet printers that use pigment-based inks; most low-cost inkjets, on the other hand, use dye-based ink, so you should steer clear of cotton rag in this instance.
