127 film is a roll film format that was first introduced by Kodak in 1912.

It was intended to be used in a new camera called the "Vest Pocket Camera", a small and portable camera that was easy to carry around. The film measures 4.7 cm wide and contains 8 exposures per roll. The image size produced is 6x4.5 cm.

The Vest Pocket Camera was an instant hit and many other manufacturers began producing cameras that could use the 127 film format, such as Agfa, Ansco, and Zeiss Ikon. The format was very popular in the 1920s and 1930s, and was used in a variety of camera types such as box cameras, folding cameras and some small portable cameras.

The Brownie Camera Page blog describes that the 127 film format was an important step in the democratization of photography, as it allowed people to take pictures who couldn't afford the larger, more expensive cameras of the time. It was also used by professional photographers for a variety of applications, such as passport photography and commercial photography.

According to the blog, 127 film cameras were produced in many countries and were sold under many different brand names. They were particularly popular in the United States, Great Britain and Germany, and were also widely used in other countries such as France and Italy.

However, with the advent of more advanced film formats such as 35mm, 127 film cameras gradually lost popularity in the 1950s and by the 1960s they were no longer in production. Despite this, there are still enthusiasts who collect and use these cameras today, as they provide a unique shooting experience and the images produced can have a special charm.  We here at Photo Hippo can process and develop both colour and black and white 127 roll film.
