What are x ray developer and fixer?
You are talking about an X-ray negative . . . it is exactly the same as a photograph negative, but instead of using light to expose the negative film like an everyday camera, it uses an X-ray machine to expose the negative film. In either case, you develop the film with, well, developer, rinse it to stop the developer, then bathe it in a bath of acetic acid (like vinegar) to make the image not be sensitive to xrays (or light) anymore.
When you expose a film in a camera the image is formed on the film and What is this image called as?
a negative
What is the meaning of film processor?
Film processing is the means of treating photographic film with chemicals after it has been exposed to produce a negative. The resulting negative can be used to make copies of the original photograph.
What is the Negative part of a light bulb?
the negative terminals
What will happen if an unexposed film is first developed then fixed then washed?
Short Answer: You will end up with a roll of clear film.I am sorry to admit that I have had this experience.Photographic film is sensitive to light. Lenses on cameras focus that light onto a flat, light-sensitive film and create a latent image. In development, the areas exposed to light are changed by a chemical process and become "hardened" onto the film. The next step is a "stop both" that stops the chemical reactions - it is usually a light acetic acid solution. This is followed by a fixative solution which removes the non-exposed areas of the film's emulsion. A final step is a "washing" bath with clear water to remove all traces of chemicals. The resulting image is a negative of the scene photographed.It is negative, because the areas that received the most light will now have the most dark grains of emulsion that have been hardened in the first chemical bath (the developer). The rest is washed away by the fixer (whic "fixes" the image). So, image areas are black, and non-image areas are clear.This negative is then used to block light that is used to expose a second piece of light sensitive material (e.g. photographic paper). A similar process to film development is used to reveal the latent image on the photographic paper. (e.g. several chemical baths done in sequence)These secondary exposures can be done with the negative in direct contact with the photo paper (making an image the same size as the film), or enlarged through a light source that uses a lens to make the image bigger. Very large enlargements will reveal the grain of the original image on the film. That is why big enlargements look grainy.So if you develop unexposed film, nothing will develop and everything will be removed by the fixer. You will have clear film. This is a mistake you do not want to experience, because you will feel you have wasted your time or your money.
Is negative film a translucent object?
Negative film is not inherently translucent, as it is typically made of an opaque material coated with light-sensitive emulsion. When exposed to light and developed, the emulsion forms a negative image that can be viewed when backlit. While light can still pass through the film to some extent, its opacity prevents direct visibility without the aid of a light source.
What are the images on film made of?
For the sake of discussion consider ordinary black and white photographic film. The quick answer: the images are made of silver. There is an emulsion of silver halide and gelatin in the film, and the silver halide reacts to light. The more light the stronger the reaction. When the particles react, they turn black. When film is exposed in a camera for a very brief period, the focused light from the scene causes parts of the film to react in proportion to the amount of light that hits that portion of the film. More light causes blacker regions of the negative, and less light causes less reaction, allowing light to shine through the negative. During the film development process, the unexposed silver halides are washed away, leaving only silver where the sliver halides have been exposed to light. This is why negatives have the distinctive look that they have, with bright parts of the actual scene appearing dark or black, and dark parts of the actual scene appearing transparent on the film. When focusing a negative in a printer, you can actually see clumps of the blackening caused by the silver halide reaction to light. Then when the negative is mounted in the printer, a projector that shines light through the negative onto the photographic print paper below, the negative is essentially reversed. Today, film photography is for all intents and purposes obsolete, but it will probably never go away. Even today photographers enjoy using many of the old techniques to produce images. There are many kinds of film using systems different from the silver processing, but the effects are the same: the more light, the darker the negative.
Why do pictures come out negative in film rolls?
Film works by absorbing the light that hits it. The more light that hits an area on the film (meaning the brighter that part of the scene is), the darker the film will get. Slide film, which produces a positive image, works the same way. You get a positive image by developing the film, producing a negative image in the exposed silver grains, then developing the film again in a different developer that works on the silver grains not exposed in the camera.

What elements used in films turns black in light negative?
Silver-based film stock turns black in a light negative, as it is developed using a chemical process that exposes the film to light and causes the silver halide crystals to darken where they have been exposed, creating the photographic image.
In photography what is a negative?
A negative is an exposed and developed piece of film where the image is not a true representation of the original. That is to say, in black and white, light and dark areas in the original scene are recorded opposite in the negative. When printed, the process reverses again, thereby producing a final image where the light and dark areas of the final print correspond to the original scene. In color film, the processed film is still referred to as a negative even though it is not truly "opposite" or negative in the same sense. In this case, the colors in the negative are the complementary colors of the original scene. When printed and developed, these produce the colors that were in the scene, so in a sense, they are reverted again. Color slide film (aka transparency film) reproduces the original scene on film, which is then projected on to a viewing screen.

Why is the image on a film a negative of the image photographed?
The light coming from the photographed object (not image) reacts to convert the silver bromide (AgBr, transparent colloid)) on the film into black (nontransparent) Ag crystals.This is the negative (reversed) image of the (positive) object.The same story with a dark object: no light, no Ag crystals = not black, still transparent!
What was used as film during the Civil War to make photographs?
Glass, chemically treated (wet-plate negative) and then exposed to light was used.
When was The Light - film - created?
The Light - film - was created in 2004.
How Did The Camera Used To Work?
Film cameras used to focus light on a light sensitive surface called film which was then put in a solution called developer that caused the image to appear. If the picture was to be printed the image on the film was negative, meaning the dark areas were light and the light areas dark. If it was to be projected onto a screen the images were positive -- like they appear to your eye. Digital cameras focus the light on light sensitive electronic sensors, then the computer in the camera interprets the information from these sensors and converts it into colors. Otherwise film cameras and digital cameras work about the same way.
Why can you get a negative image when light reacts with silver chloride?
The light that makes the image on a film coated with silver chloride is absorbed by individual grains of solid silver chloride, and this absorption leaves the silver ions in an excited state, with more energy than the ions not exposed. The stronger the light, the more silver chloride grains in the image are exposed. When the exposed film is "developed", traditionally in a bath of sodium thiosulfate solution, the excited silver ions are reduced to metallic silver, which is black because it is so finely divided. Therefore the portions of the film that received the most light when forming the photograph become the darkest in the negative formed by development. When light is projected through the developed negative onto photosensitive print paper, the darkest areas of the negative allow very little light through them and the lighter ones allow more light, so that the lighter and darker areas are reversed again to form a positive image.
When was Let There Be Light - film - created?
Let There Be Light - film - was created in 1946.
