Often 35mm film comes in tight single spooled metal cassettes.

APS Negatives: (also referred to as Advantix)

APS stands for Advanced Photo System and was developed by Kodak in 1996 to give photographers the option to shoot in three photo sizes. Below are the definitions for the three photo size options.

APS Negatives come in a long plastic cassette (image below). Numbered symbols (called 'visual indicators') on the cartridge end indicate the status:

• Full circle: Unexposed
• Half circle: Partly exposed
• Cross sign: Fully exposed but not processed
• Square: Processed

Important Note*: Please only send processed APS cassettes where the square is selected. See images below.

Disc Film:

Below is an example of disc film. This film is in the form of a flat disc, and is fully housed within a plastic cartridge. Each disc hold15 exposures with the disc being rotated 24° between each image. The fifteen 11mm x 8mm images themselves are arranged around the outside of the disc. This type of film was developed by Kodak in 1982 but was discontinued in 1998.

Important Note*: We do not currently process Disc Film

126 Instamatic: (also referred to as Instamatic)

126 is the number given to a cartridge-based film format. It was introduced by Kodak in 1963, and is associated mainly with low-end point-and-shoot cameras, particularly Kodak's own Instamatic series of cameras. Although 126 was once very popular, as of 2006 it is no longer manufactured. The frame size is 28mm x 28mm and has only one perforation at the bottom.

120 Medium Format:

Medium format has traditionally referred to any film size in-between 35 mm and large format (4"×5" or more) sheet film. The most common medium format film is 6cm x 6cm with a frame size of 56mm x 56mm. The number of the frame is usually printed on the top or bottom of the frame. Medium format is often used by professional photographers because it offers higher image resolution than traditional 35mm (135) film. Other medium format sizes included 6cm x 4.5cm, 6cm x 7cm, 6cm x 8cm and 6cm x 9cm.

Large Negatives:

Large Negatives are usually medium format negatives housed in a 70mm x 70mm mount. The mounts are usually made of plastic or dense cardboard. Large negatives are sometimes matted, meaning they are encased in a plastic or cardboard mount bigger than 70mm x 70 mm.

Large Transparencies:

Large Transparencies are a thin sheets of transparent flexible material, typically cellulose acetate, onto which figures can be printed or drawn. These are then placed on an overhead projector for display to an audience. Large transparencies are typically the approximate size of a legal sheet of paper 8 ½ "x11", however they can range in various sizes.
