Large format (photography)
（重定向自Large format camera）
Large format refers to any imaging format of 4×5 inches (102×127 mm) or larger. Large format is larger than "medium format", the 6×6 cm (2¼×2¼ inch) or 6×9 cm (2¼×3½ inch) size of Hasselblad, Rollei, Kowa, and Pentax cameras (using 120- and 220-roll film), and much larger than the 24×36 mm (~ 1.0x1.5 inch) frame of 35 mm format. The main advantage of large format, film or digital, is higher resolution. A 4×5 inch image has about 16 times the area, and thus 16× the total resolution, of a 35 mm frame.
