Analog photography, also known as film photography, is a term usually applied to photography that uses chemical processes to capture an image, typically on paper, film or a hard plate. These processes were the only methods available to photographers for more than a century prior to the invention of digital photography, which uses electronic sensors to record images to digital media. Analog electronic photography was sometimes used in the late 20th century but soon died out.
Contrary to the belief that digital photography gave a death blow to film, analog photography not only survived, but actually expanded across the globe.[1] With the renewed interest in traditional photography, new organizations (like Film Is Not Dead, Lomography) were established and new lines of products helped to perpetuate analog photography. In 2017, BH Photo & Video, an e-commerce site for photographic equipment, stated that film sales were increasing by 5% each year in the recent past.[2]The Japan Times claimed that though film photography is a "dying art", Japan could be at the starting point of a movement led by young photographers to keep film alive.[3]Firstpost claimed that a vast majority of photographers are slowly coming back to film.[4]
Decline and revival

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.
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.
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]

In optimal processing and storage conditions, a film can have a lifetime duration.
Disadvantages
Film photography requires photographers to invest more time and skill than digital.
Film is delicate and requires careful handling, refrigeration, protection from the sun, protection from dust, etc.
Film negatives and slides require proper developing, or they may suffer from deterioration such as fogging.
Processing film is expensive and requires additional investment such as scanning, enlarging, or printing.
Material

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.
