Introduced in 1934, the standard 35mm filmstrip contains four, 24mm x 36mm frames. This film format is still in production as a niche format, though Kodak stopped producing it in 1995. Introduced in 1912, 127 film is 46mm wide, between the 35mm and 120 “medium format.” The viewable area of 127 negative film is about 40mm x 40mm. 620 film is also the same as 120 film, but the core of the spool and the end flanges are smaller. This format is 60mm wide, and the frame number can be found printed at either the top or the bottom.Ģ20 and 620 formats are similar to 120, but they allow for more exposures per roll, as 220 film is double the length of 120 film. The most common of these sizes is the 6圆cm size, which has a frame size of 56mm x 56mm. Introduced in 1901, 120 medium format contains a range of frame sizes: 6×4.5cm, 6圆cm, 6x7cm, 6x8cm, and 6x9cm. Film for larger cameras could be as large as a full sheet of paper, so it’s not too difficult to differentiate between some of the more common film negative sizes. In general, the film for 35mm photographic cameras (the most common) comes in long and narrow strips of chemical-coated plastic. You can identify what type of film negatives you have by examining the size and appearance of your negatives. If you’re not sure which old negative format you have, read on.

Though film has become popular again in photography, modern versions of film cameras have been updated with upgraded features. Negative film can be in color or black and white. Negatives are the inverse of positive images, wherein blacks appear white and whites appear black.
