Lomography. The original Lomo LC-A Lomography is an analog camera movement and community, and is also a commercial trademark of Lomographische AG.

Lomography

The Lomographic Society International was founded in 1992 by a group of Viennese students after they discovered the Lomo LC-A camera[1] created by LOMO PLC of Saint Petersburg, Russia. Lomography started as an art movement through which the students put on exhibitions of photos within Vienna; the art movement then developed into a commercial enterprise. Since 1995, Lomography has been the sole distributor of the LC-A camera outside of the former Soviet Union, and has moved into producing their own range of analog cameras, films and accessories. The Lomographic Society was formed in 1992 and maintains a strong community following through the internet. History[edit] Lomography is a community of Lomographic photographers who advocate creative and experimental film photography.

NikonD700 — a 12.1-megapixel full-frame DSLR Until the advent of such technology, photographs were made by exposing light sensitive photographic film, and used chemical photographic processing to develop and stabilize the image. By contrast, digital photographs can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing. Digital photography is one of several forms of digital imaging. Digital images are also created by non-photographic equipment such as computer tomography scanners and radio telescopes.

Digital images can also be made by scanning other photographic images. The digital camera[edit] History[edit] The first true digital camera that recorded images as a computerized file was likely the Fuji DS-1P of 1988, which recorded to a 16 MB internal memory card that used a battery to keep the data in memory. Sensors and storage[edit] How Digital Cameras Work" In the past twenty years, most of the major technological breakthroughs in consumer electronics have really been part of one larger breakthrough.

How Digital Cameras Work"

When you get down to it, CDs, DVDs, HDTV, MP3s and DVRs are all built around the same basic process: converting conventional analog information (represented by a fluctuating wave) into digital information (represented by ones and zeros, or bits). This fundamental shift in technology totally changed how we handle visual and audio information -- it completely redefined what is possible.

The digital camera is one of ­the most remarkable instances of this shift because it is so truly different from its predecessor. Conventional cameras depend entirely on chemical and mechanical processes -- you don't even need electricity to operate them. On the other h­and, all digital cameras have a built-in computer, and all of them record images electronically. ­

The new approach has been enormously successful. Photography – Film Types and Film Speed. The final result of your photographic ventures is a roll of film, a handful of prints or box of slides.

Photography – Film Types and Film Speed

Other than your choice of lens, the film choice will have the biggest impact on the quality of the final results. Digital Cameras While most of this is irrelevant for digital cameras, “film” speed still applies. In this case the speed affects the noise level rather than grain size but the final result is somewhat similar. Choose the smallest ISO for the required shutter speed, ie to allow hand-held shooting or freezing sports action.

Choosing a Film 1. Print greater exposure latitude (some 9 stops vs 5 stops for slide) cheaper easy for prints ideal for cheap compact cameras Slide (also known as reversal or tranparency film) greater colour saturation and contrast (especially professional film) no “middle-man” adjusting colour balance or exposure much easier to digitise requires good camera to obtain correct exposure Black and white film is all negative nowadays. 2. ISO 400. Photographic film. This article is mainly concerned with still photography film.

For motion picture film, please see film stock. Undeveloped Arista black-and-white film, ISO 125/22° Photographic film is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. How Does Photographic Film Work? Cross processing. A cross processed shot of mannequins Cross processing (sometimes abbreviated to Xpro) is the deliberate processing of photographic film in a chemical solution intended for a different type of film.

Cross processing

The effect was discovered independently by many different photographers often by mistake in the days of C-22 and E-4. Color cross processed photographs are often characterized by unnatural colors and high contrast. The results of cross processing differ from case to case, as the results are determined by many factors such as the make and type of the film used, the amount of light exposed onto the film and the chemical used to develop the film. The effect can also be achieved with digital filter effects such as with the photo-sharing mobile application Instagram. Processes[edit] Cross processing usually involves one of the two following methods. However, cross processing can take other forms, such as negative color print film or positive color reversal film in black and white developer.
