110 film

There is a continuous backing paper, and the frame number is visible through a window at the rear of the cartridge.

The film is usually pre-exposed with frame lines and numbers, a feature intended to make it easier and more efficient for photo finishers to print.

Unlike later competing formats, such as disc and APS film, processed 110 negatives are returned in strips, without the original cartridge.

[3] As of 2024, they offer 110 Black and White, Color Negative, and a variety of experimental stocks such as Lomochrome Purple and Metropolis.

The Reese's Camera was meant to resemble two Reese's two packs stuck together (it used a generic, likely pre-existing mold, it was just molded in orange and had Reese's stickers on it), while the Hidden Camera came with a removable cardboard cover sleeve with small cutouts for the trigger button and front lens that made it resemble a Good & Plenty candy box.

The Hidden Camera had a periscope-like attachment that used a mirror for taking pictures around corners or behind objects.

[5] Although the format is most closely associated with cheaply produced, low-cost cameras, Canon, Minolta, Minox, Pentax, Rollei, Voigtländer, and others, as well as Kodak, offered sophisticated, expensive 110 cameras, with excellent multi-element focusing lenses and precise, electronically controlled exposure systems.

This has led to the misconception that the cartridge itself is incapable of holding film flat enough for making high-quality negatives.

Only a few cameras took advantage of this feature: Rollei A110, Canon 110 ED 20, Minolta 110 Zoom SLR Mark I/II, Minox 110S, Voigtlander Vitoret 110 EL, Pentax Auto 110 and the Kodak Ektralite 10.

[7] As shown in the photograph to the right, these cartridges can be modified by hand so that they signal the proper speed to the camera.
