Analog photography

A wet plate camera made in 1866.

As digital photography took over, Kodak, the major photographic film and cameras producer, announced in 2004 that it would stop selling and manufacturing traditional film cameras in North America and Europe.[5][6] In 2006, Nikon, the Japanese Camera maker announced that it would stop making most of its film cameras.[7] Incurring losses in the film camera line, Konica-Minolta too announced its discontinuation of cameras and film.[8] In 2008 the first instant film maker Polaroid announced it would stop making instant film.[9]

Interest in all types of film photography has been in the process of revival. The Lomography movement started in 1992, which, BBC claimed, has saved film from disappearing.[10] Lomography started manufacturing updated versions of toy cameras like Lomo LC-A (as Lomo LC-A+), Diana (as Diana F+), Holga, Smena and Lubitel.

Film photographers started experimenting with old alternative photographic processes such as cyanotypes, double exposures, pinholes, and redscales. Worldwide Pinhole Photography Day is observed on the last Sunday of April, every year.[11] Organizations such as Roll4Roll spread the artistic movement of double exposures.[12]

Film Photography Project, a website dedicated to film photography, announced in 2017 the comeback of large-format camera by a new startup called The Intrepid Camera Co.[13]

Popularity

For those who are keen to work with, or do work with more traditional types of photography, dedicated online communities have been established in which like-minded individuals together share and explore old photographic practices.[14] Film photography has become much more popular with younger generations who have become increasingly interested in the traditional photographic practice; sales in film-based cameras began to soar, and youth were seen to embrace some 19th-century technology.[15] Young photographers say film has more 'soul' than digital.[16] Camera manufacturers have also noticed the renewed interest for film, and new simple point-and-shoot film cameras for beginners, have started to appear.[17]

Polaroid was once a power in analog instant photography. Facing the digital revolution, Polaroid stopped production of instant film in 2008. A new company called Impossible Project (now Polaroid through brand acquisition) acquired Polaroid's production machines in order to produce new instant films for vintage Polaroid cameras and to revive Polaroid film technologies.

Art forms

The revival of analog photography has resulted in new art forms and photo challenges, as the technical limitations and constraints of film are used as parameters of the art. In the 36 (or sometimes 24) frames challenges, a single roll of film must capture a specific event, time period or as exercises to improve photography skills.[18][19]

In contact sheet photography, the traditional contact sheet is used as a way to make pictures consisting of partial photos. The resulting image spans the whole sheet, divided into squares by the black borders of the film.[20]

Contemporary tintype, 2004

Film photography does not just mean photographic film and its processing with photo chemicals. Itself a science and a craft of its own, changes in chemistry and developing time will affect the end result. An example is tintype photography. A tintype, also called ferrotype, is a positive photograph produced by applying a collodion-nitrocellulose solution to a thin, black-enameled metal plate immediately before exposure. The tintype, introduced in the mid-19th century, was essentially a variation on the ambrotype, which was a unique image made on glass instead of metal. Just as the ambrotype was a negative whose silver images appeared grayish white and whose dark backing made the clear areas of shadows appear dark, so the tintype, actually negative in its chemical formation, was made to appear positive by the black plate.[22] These methods were not abandoned when film came to dominate photography.

Instant film develops an image automatically, and soon after it is ejected from the camera without any processing by the photographer or by a photographic lab. Photographic paper, however, must be processed after exposure in a dark room or photographic lab.

Black-and-white negative film may be processed using a variety of different solutions as well as processing time control, depending on the film type, targeted contrast, or grain structure. While many B&W processing developers are no longer made commercially, (Dektol, D-76 and T-Max developers are still made) other solutions may be mixed using original formulas. Color negative film uses C-41 process, while color reversible film uses E-6 process for color slides. Kodachrome used to have its own process with one developer bath per each film color layer.

Meanwhile, alternative photographers experiment with different processes such as cross processing which yields unnatural colors and high contrasts. This basically means processing a reversal film using a negative developer bath, or the contrary.

For a more sustainable photography, black and white negative film may be processed in plant-based chemicals at home.

Film processing does not use digital technology, since information is not translated into electric pulses of varying amplitude or binary data.
