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.
What else can I help you with?
What was the first Hollywood film which was made of computer images?
Made by Pixar , Toy Story was the first feature-length computer-animated film .
How are photographic images made permanent?
Photographic images are made permanent through various processes, depending on the medium used. In traditional film photography, light-sensitive chemicals on the film capture images, which are then developed and fixed to make them stable. In digital photography, images are stored as digital files on memory cards or drives, where they can be saved indefinitely. Additionally, prints can be made using ink or photographic paper, which can also be treated to enhance longevity.
Which type of scanner generally has high costs but produces top-quality images?
The highest quality scanned images from film originals are made with drum scanners.
What does the film in a camera do?
Camera in the film will store images so that it can be developed.
What are the main differences between developed and undeveloped film?
The main differences between developed and undeveloped film are that developed film has been processed to reveal the images captured on it, while undeveloped film has not been processed and therefore does not show any images. Developed film is ready for viewing and printing, while undeveloped film requires processing before the images can be seen.
What is the optimal resolution for capturing images on 35mm film?
The optimal resolution for capturing images on 35mm film is typically around 12-16 megapixels.
How can you determine if your film camera is capturing images properly?
To determine if your film camera is capturing images properly, you can: Check the focus and clarity of the images by examining them closely. Ensure that the exposure settings are correct for the lighting conditions. Develop the film and inspect the developed images for any issues such as blurriness or overexposure. Compare the images to your expectations and previous successful shots to see if they meet your standards.
What was the name of the scientist who made film projector?
The film projector was invented by Thomas Edison, an American inventor and businessman. Edison's creation allowed for the projection of moving images onto a screen, revolutionizing the entertainment industry.
What is a film that is based on drawings or computer images?
A cartoon
How are images stored on camera film?
In particle of dye.
What technology is used to store miniaturized images on roll of film?
Miniaturized images on a roll of film are stored using a chemical process involving light-sensitive emulsions. When the film is exposed to light, the emulsion undergoes a chemical change, capturing the image. After exposure, the film is developed through a series of chemical baths that reveal the images. This analog technology contrasts with digital methods, which use electronic sensors to capture images.
How can I scan 35mm film at home?
To scan 35mm film at home, you will need a film scanner or a flatbed scanner with a film scanning attachment. Place the film strip in the scanner, adjust the settings for film scanning, and then scan the images onto your computer. You can use editing software to enhance the scanned images if needed.
