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.
All photography need light What type of light is needed to create a negative?
To create a photographic negative, you need light that can expose the photosensitive material, typically ultraviolet or visible light. This light interacts with the light-sensitive chemicals in the film or photographic paper, causing a chemical reaction that records the image. The intensity and duration of light exposure are crucial for capturing the details of the scene. Without adequate light, the negative will not form properly.
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.
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 Negative part of a light bulb?
the negative terminals
Is negative film a translucent object?
Negative photographic film; both black and white, and colour; are both opaque before they are developed. After development, they are transparent, translucent, or opaque depending on the part of the photographic image.
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.
What would you conclude if a negative film turned out completely black?
If a negative film turned out completely black, it likely indicates that the film was either overexposed to light or not properly developed. This means that the light-sensitive emulsion on the film was saturated, preventing any image from forming. Alternatively, it could suggest a malfunction during the development process, such as using incorrect chemicals or not following the development time accurately. In either case, the result is an unusable film without any discernible images.
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.
Is color negative film black and white?
No, color negative film is not black and white. It is designed to capture and reproduce colors in a negative image format.
When was The Light - film - created?
The Light - film - was created in 2004.
