127 ROLL FILM History and Facts Tips & Tricks
Kodak always advertised with a Kodak instead of a Camera, that's how people would always associate photography with kodak.
The Vest Pocket Kodak was true to its name, “small enough to be carried in a waistcoat pocket without inconvenience”. With this new compact Kodak, of course, a new photographic film also had to be launched.
127 film is a paper-backed rollfilm format. 127 film is 46mm wide and was originally designed to take eight pictures in 4x6.5cm format. In 1930, during the Great Depression, the camera makers tried to economize on the use of film, and cameras began to appear taking 16 exposures in 3x4cm format on the 127 film.
On the back of the camera you can see which photographic format it is. With the format 40 mm x 30 mm there are 2 red viewing windows, the 1 in the first one takes photo 1A and in the 2nd 1B.
In the 1950s there was a short revival of the 127 film with cameras designed to take 12 exposures in 4x4cm format. The film was wildly successful on its release because of its affordability. The film was produced in several variations, black and white negative / slide positive, color negative / positive.
Most cameras made for 127 roll film are inexpensive and easy to operate models. The 127 format also birthed some truly impressive cameras from the likes of Rollei, Zeiss, and other legendary brands.
In the late 1950s to early 1960s, spy cameras were made in Hong Kong especially for the children. With this camera you could take pictures just like dad.
Kodak stopped producing 127 film in July 1995. At the moment there are still a few companies that produce the 127 roll film. There are also a number of companies that spool films to your likings.
Roll Film Made since 1888
Roll film is any type of spool-wound photographic film protected from white light exposure by a paper backing. The opaque backing paper allows roll film to be loaded in daylight. It is printed with frame number markings.
In 1881 a farmer, Peter Houston, invented the first roll film camera. His brother David, filed the patents. He was issued an 1881 patent for a roll film holder which he licensed to George Eastman. The Kodak introduced in May 1888 was the first commercially successful box camera for roll film.
All films are packed in a box in an air and light-tight foil. In this package, the film is on a spool.
On the outside is a paper roll with the indication of the photo numbering printed on it.
On the outside of the film, the Filmbase is a flexible film foil.
The photosensitive emulsion layer is on the inside.
Every Roll Film has the same construction. The most important thing is to pay attention to which format of film fits in which camera.
Film is the general name for a light-sensitive material coated onto a flexible backing. Manufacturing film is a complicated process that demands specialist equipment. The film base is made from polyethylene.
Once the film is coated with emulsion, it enters the chill box where it’s cooled on rollers.
The dryer consists of 19 sections where the film is dried slowly and gradually. This is to ensure that there are no imperfections in the end product.
Once the coating process is completed, the materials are transported to the finishing area in a completely different building. To avoid any contact with light, the transportation is done by placing the materials in light-tight boxes called coffins. They are now ready to be cut to the different film formats.
A photographer´s choice of film is not of size or camera loading. There are also different kinds of emulsion which affect the film´s speed and its sensitivity.
Ever since two film standards called ASA and DIN were combined into ISO standards in 1974, they were referred to as one word “ISO” from that point on. Quite simply, when you double your ISO speed, you are doubling the brightness of the photo.
Finally we come to grain. This is not very obvious on small prints, but apparant in enlargements.
We have already gained a idea of what photography is all about. We have chosen a film and have exposed it. Now the image is not visible. For that we have to develop the film. For that we need a dark room or darkbag and a developing tank.
The films are divided into 3 types: black and white, colors, and reversals. Every filmtype needs a different processes. When we have the right film with developer.
When the process is done and the film is fixed the film can be rinsed in clean water and dryed. Now you have the negatives ready to print or scan.
