Cameras and lenses Basic camera functions In its simplest form, the camera is a light-tight container carrying a lens, a shutter, a diaphragm, a device for holding and changing the film in the correct image plane, and a viewfinder to allow the camera to be aimed at the desired scene. The lens projects an inverted image of the scene in front of the camera onto the film in the image plane.

People never think of what goes in to the developing process. They do not think about all the chemicals that go into developing the pictures. Many people just wonder why their picture came back with nothing on it or why they look like a ghost.
They do not even bother to think about all the chemistry that goes on to develop the pictures. They think of how much money they just wasted on a bunch of messed up pictures.
If they were to sit down and think about all the chemicals that went into making that one picture they would view it differently.
Photography is just another form of chemistry when it comes down to it. In the year a chemist by the name of Joseph Wilson Swan produces the first way to develop film. What was known as the auto type process was created by using a gelatin film soaked in carbon or other pigment granules.
This process would then be photosensitized by using potassium dichromate.
Later inhe produced the bromide printing paper that we now use in standard photographic medium. Since photography has been around for about years the chemicals used to make both motion pictures and still pictures are the same. AWP Both motion and still photography share many similar chemicals such as fixers, developers, and stop baths.
Also from the very beginning the durability and stability of pictures has been a problem. The fine-grained and superficial silver, the paper and plastics as base, the gelatin, albumin as binding agents, which was found in many black and white photos were affected greatly by the environmental conditions.
It was not in till that Kodak came out with the first color film. That was the birth of modern day film. The durability of the color film though was worse then the black and white.
With the color dyes and no longer the metallic silvers the colors were under the problems of the environment.
They had to be put under sun light, chemical agents, heat, and moisture. Then when the pictures where stored wrong the colors also got bleached out.
It is virtually impossible to restore the original photo. AWP So now the goal of these people who are trying to restore these black and white photos is to reproduce the original colors of the bleached photo instead of restoring the original dyes.
Not only do we face the problem of faded photographs we also face the problem of having to fix scratched or dusty films. In order to remove the scratches a classical liquid gate printing method gets used.
The liquid gate is applied to both sides of the original film. The liquid fills the scratch and reduces the light scatter. When processing film most photographers prefer to use black-and-white film because of how much easier the development process is. When you develop the photographs you need to have developers, stop baths, fixers, washing aids, wetting agents ,water, film cleaner, reducers and intensifiers, and paper.
Davis Each of these agents have there own purpose to be used. Many of the chemicals also come in liquid or powder form. There are two kinds of developers; one for film use and one for paper. Davis The most common developing agents are hydroquinone, Metol, and phenidone.
Developing agents are to weak to work alone so they must work with an accelerator. The accelerator is used to activates the developing agent. When you mix a developer with a strong accelerator you will get a quicker developing time and a higher contrast.
The quicker accelerator also has bad side effects like excessive fog, soft emulsions, course grain, and shorter developer life.Calotype or talbotype is an early photographic process introduced in by William Henry Fox Talbot, using paper coated with silver r-bridal.com term calotype comes from the Greek καλός (kalos), "beautiful", and τύπος (tupos), "impression".

For teenagers, taking pictures is something pleasant and relaxing. You can see students taking photos all the time, even if they are using a mobile phone or a professional camera. Photographic prints that will be hung on a wall or placed in a portfolio can be shown in a variety of ways.
Prints can be trimmed and then tacked to the wall or placed in a box or portfolio. Pornography term papers (paper ) on Photography: When someone says the word photography the first thing that most people think of is pictures.
People never think of what goes in to the developin. Term paper Photography – process of making pictures by the action of recording light patterns, reflected or emitted from objects, on a photosensitive medium or an image sensor through a timed exposure.
The process is done through mechanical, chemical, or electronic devices known as cameras.
