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. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film.
The emulsion will gradually darken if left exposed to light, but the process is too slow and incomplete to be of any practical use. Instead, a very short exposure to the image formed by a camera lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent image in the emulsion, which can be chemically developed into a visible photograph. In addition to visible light, all films are sensitive to ultraviolet, X-rays and high-energy particles. Unmodified silver halide crystals are sensitive only to the blue part of the visible spectrum, producing unnatural-looking renditions of some colored subjects. This problem was overcome with the discovery that certain dyes, called sensitizing dyes, when adsorbed onto the silver halide crystals made them respond to other colors as well. First orthochromatic (sensitive to blue and green) and finally panchromatic (sensitive to all visible colors) films were developed. Panchromatic film renders all colors in shades of gray approximately matching their subjective brightness. By similar techniques special-purpose films can made sensitive into the infrared (IR) region of the spectrum.

Kodak 1958 factory film This fascinating 1958 documentary titled, "How Film is Made", that documents the production process and birth of photographic and cinematic film, was initially discovered as part of a heritage in the Netherlands. Although its exact source and purpose are as of yet still unknown, it may have been an instructional film for new employees at Kodak's factories world wide, and was probably used as a promotional film for the general public as well. The original 16mm film came into the hands of Frank Bruinsma of the Super 8 Reversal Lab in the Netherlands, who decided to have it digitized in conjunction with CINECO and the help of others, and make it available on the internet. After a member of the Analog Photography Users Group (APUG) pointed out its availability, a ...
Developing 35-millimeter film is done by loading the film into a developing reel, placing the reel into a lightproof tub, pouring in the appropriate chemicals and rocking the tub back and forth to coat the film.

The unfortunate history of racial bias in photography. Subscribe today: http://goo.gl/0bsAjO For decades, the color film available to consumers was built for white people. The chemicals coating the film simply weren't adequate to capture a diversity of darker skin tones. And the photo labs established in the 1940s and 50s even used an image of a white woman, called a Shirley card, to calibrate the colors for printing. Concordia University professor Lorna Roth has researched the evolution of skin tone imaging. She explained in a 2009 paper how the older technology distorted the appearance of black subjects: "Problems for the African-American community, for example, have included reproduction of facial images without details, lighting challenges, and ashen-looking facial skin colours co...

ABOUT THIS VIDEO This is a video for Street Hunters (http://www.streethunters.net). Spyros Papaspyropoulos is the co-founder of www.streethunters.net and a passionate Street Photographer from Greece. In this video he goes on his 11th "Street Hunt" this time at the city of Iraklio (or Heraklion) in Crete, Greece. He is using a Canon Canonet QL17 camera with a fixed 40mm f1.7 lens. He is using Kodak Ektar 100 colour film. The 100 stands for the ASA or ISO of the film.

Video snippets from a few areas of the Ilford Factory. I spotted a posting from Ilford Photo (Harman Technology) online a few months back offering a day's tour of their photographic film and paper factory based in Mobberley, Cheshire. Being a complete film obsessive, as well as a love of industry in general this was too good an opportunity to miss. Emails were exchanged, accommodation booked and the 18th November 2013 was the big day. As I navigated my way through the security gatehouse and through the vast site to the training centre I did feel a bit like Charlie on his way to the Chocolate Factory with a golden ticket. But with FILM! Read a full writeup of the day, with pictures here: http://this-is-sunderland.co.uk/2013/12/15/ilford-factory-tour-where-black-and-white-film-is-made/ ...

Director: Mario Gariazzo (as Roy Garrett) Writer: Mario Gariazzo (as Roy Garrett) Stars: Ray Lovelock, Anna Maria Rizzoli, Mario Cutini A milestone production from Mario Gariazzo, notorious for his tasteless sexploitation epics such as The Sexorcist / L'Ossessa. Assembling here one of the worlds finest trash film collectives and eschewing all correct agendas, the director punctuates his fleshy tapestry with incredibly sleazy imagery involving Marina Hedmann/Frajese and Patrizia Di Rossi/Webley. At the garishly lit Play Motel, these two warhorses and other bleached blondes are first seen being secretly photographed while having sex. As the film serves also as a giallo, they are later stabbed to death by an assassin dressed in black. Conveying a sense of mad comedy, this inexhaustible suppl...
