[edit] Color film
Because of color shifts, color film usually does not lend itself to variations in development time.
Color film is both sensitive to and records both value (dark and light) and hue (colors). Color film comes in both negative (to make prints) and positive (to make transparencies, or slides).
Color film that is color balanced for scenes illuminated by artificial light sources at a color temperature of 3200K, typically tungsten and household lamps. This is the more commonly used of the two types: A and B.
Nikonians Photo Glossary ...
Color film has three different layers of light-sensitive materials, which respond, in turn, to red, green and blue. When the film is developed, these layers are exposed to chemicals that dye the layers of film.
A color film that is color balanced to work under tungsten lighting. To use a tungsten type film type under daylight or flash, a color temperature conversion filter is needed. This film is also known as Type B film.
Nikonians Photo Glossary ...
All color films suffer from reciprocity failure when exposed for longer than a few seconds. This results in a color shift as the three layers of the film respond to a different degree. The exact color will depend on the brand of film you are using.
With color film, this becomes trickier. Look carefully at the curves for the Agfachrome slide film. Notice how they diverge a bit when the light is scanty. The different layers of the film are reacting differently.
How a color film reproduces the colors of a scene. Color films are made to be exposed by light of a certain color quality such as daylight or tungsten.
If the color film or paper is of the reversal type (i.e., if processing gives a direct positive result, without involving a separate negative) the first processing step is essentially an ordinary black- and- white development.
In some color films where tabular-grain (T-grain) emulsions are used, high speed and increased sharpness are combined.
As with color film labs, evaluate their ability to handle dust and their spot editing skills. A few black and white processing labs to investigate include A&I and Kodak (aka Qualex).

Daylight color film - color film intended for use with daylight or a light source of similar temperature. The film is color balanced to 5400 K.
Daylight tank - light tight container for film processing.
Kodak Vericolor film is a colour negative film normally used for making positive transparencies from colour negatives (slides from prints) and internegatives, but will produce a colour negative of the subject when used in a camera.
Daylight color film. Color film balanced for use with flash, daylight or daylight-matching strip tubes (5500 K). strong ...
Years ago, when color film came onto the scene, black-and-white imaging began to fade in popularity-especially in wildlife photography, with its emphasis on naturalism. But monochrome has returned with a vengeance with the advent of digital.
Daylight film. Color film that has been balanced to produce natural-looking color when exposed in daylight.
-Type A film - color film balanced to artificial light sources at a color temperature of 3400K.
-Type B film - color film balanced to artificial light sources at a color temperature of 3200K.
One of the biggest problems with color films and DSLRs is the limited dynamic range. Print films tend to have around five stops of dynamic range. Slide films only have about three. DSLRs usually have about five stops, perhaps a bit more.
Day light film: Color film for use in daylight or flash. These films are balanced to 5400K.
Depth of field: The distance between the nearest and the furthest point in the subject that can be brought to sharp focus.
Unlike color film that allows us to differentiate objects based both and color and contrast, B&W film causes adjacent objects of different colors to appear to merge if each has the same luminance.
We now have fast color films but the real news for available light can be expressed with one word: digital. Well, actually two words: digital and RAW. But first let's examine available light work with present-day film, especially color negative.
After all, color film contains silver halide too. Fuji's stance is somewhat reassuring to photographers like me who have used their products for years, especially since Velvia came on the scene.
The color film is the most popular one but off late B&W photos are coming to the forefront. The good thing about black & white film is that you can create an artistic look.
Color films are made to be exposed by light of a certain color quality such as daylight or tungsten. Color balance also refers to the reproduction of colors in color prints, which can be altered during the printing process.
If there was ever a location for which color film was invented, this was it.
Just before the start of World War II, Fuji had begun work on the development of a color film. The war intervened, however; and the Japanese government ordered Fuji to produce film for military uses, which precluded any further research of color film.
Well the answer lies in the way that color film works. There are basically three color sensitive layers, one sensitive to red light, one to green light and one to blue light.
Black-and-white or color films can be used. Negative films having an ISO of 400 are often shot to compensate for the limited range of camera adjustments.
Of course, you can use black-and-white or color film. (While it's best to return to the original source, if film has been lost or damaged, you can even start with a print.) This allows easy, economic access to the traditional silver darkroom.
The electric hues of tropical fish cried out for color film, and my vision was far more influenced by Ektachrome (and later, Velvia) than by my trusty Plus-X.
However and again, today, when most modern digital camera sensors and color films -although not all- are insensitive the UV light, ...
Most contain high-quality 35mm color film. Some also have a flash, and some models are water resistant for use in shallow water or otherwise wet conditions.
1907: The first commercial color film is developed.
1936: Kodachrome, multi-layered color film, is developed.
1937: Photojournalism becomes an important part of reporting WWII news.
Chapters proceed in the same order as image production and address theories and techniques of color and b&w photography, color film processing, and b&w processing and printing.

Color film doesn't record color images either, it also works by producing colored "layers" or channels using colored dyes layered over a reflective sub straight. It actually doesn't magically record and then reflect chromaticism either.
Color Balance - Refers to how a color film reproduces a scene's colors or to how well colors appear in print reproductions.
Color Depth - See "Bit Depth." ...
This process started before color film was available and was very popular in the late 1800s with traveling photographers who sold portraits by going door to door in rural areas.
Its departments cover all facets of photography from color film use and development to large format equipment. In addition, it contains information about collecting photographic equipment and news from the international photography world.
The same rule applies to negative color films as black and white films. The lower the ISO number, the finer the grain.
Transparency Films ...
Another important fact, albeit of a technical nature, to keep in mind is that black and white film has a much wider latitude than color film, thus allowing a much wider range of tones to be captured.
We chose several walk-in and mail-order film photoprocessing labs. Read Color Film Processing: Mailers vs. Big Boxes to find out the results.

In addition to color, some cameras let you also shoot images in black and white or in an antique sepia tone. Some even have modes that mimic the colors captured by color film.
Filter for use in front of the lens that absorbs all visible wavelengths to a more or less equal extent. ND filters can be used with both monochrome and color films, since they have no effect on color balance.

Loss of effective film speed, contrast changes, and (with color films) color shifts are the three common results. These changes are called reciprocity effect.
(1) a film positive, either black and white or in color; (2) a printed piece on clear or transparent sheeting with transparent or translucent ink for backlighting in a display; (3) a positive image on photographic color film; ...
When exposure times fall outside of this range-becoming either significantly longer or shorter-a film's characteristics may change. Loss of effective film speed, contrast changes, and (with color films) color shifts are the three common results.
Many of us had several backs for each cameras so we could have black and white film loaded in one and several different ISO rated color film in others. Thanks for the offer, Sy, but I no longer have any of my Polaroid cameras or Polaroid backs.
