Kodak Portra 160 is the lowest ISO entry in Kodak's professional family of Portra films. It is a near-perfect film with excellent color accuracy, extremely fine and smooth grain, high detail, an extremely wide latitude, and a very pleasant amount of contrast. The film excels in all lighting conditions but is particularly well suited for direct sunlight, where a degree of control over the harsh contrast is sought. While it is popularly used for various types of portraiture, Portra 160 makes an excellent landscape, cityscape, street, product, and still life film as well. It is available in a variety of formats, including: 35mm, 120, 4x5, and 8x10. Portra 160 is the kind of color film you can never go wrong by having in your camera.
The 620 format shares many similarities with 120. The film and backing paper are identical with the only major differences being in the dimensions of the spool that 620 film is wrapped upon. 620 spools have thinner end caps, a smaller "keyhole" at each end of the spool and a thinner center column with a smaller circumference. These differences can prevent most 620 cameras from accepting film on 120 spools, and vice versa. No companies directly manufacture 620 format film anymore. Instead there are various sources which make 620 spools and then re-spool 120 film onto these spools.
