Glossary

auto-advance- a feature on some film cameras that automatically advances from one negative to the next

binary code- a code of 1's and 0's based on the amount of light that a digital camera "remembers" to store the image

CCD- Charge-coupled devices, have tiny resistors that sample the light that hits them and creates an image, using red, green, and blue filters to make color. Creates binary code so the image can be stored.

chemicals- includes stop bath, developer, and fixer, used to print photos from film negatives

compressed- a file's size is made smaller, while its quality and resolution are decreased

darkroom- a place where film negatives are developed with special equipment, including chemicals (see above), photo paper, and an enlarger

expose- to open the shutter and let the light

film- a form of recording images, predecessor to CCDs and memory cards. A roll of plastic coated with light-sensitive silver halide crystals.

flash- a device, usually external, which quickly flashes bright light to make a photo brighter while the film or CCD is being exposed

halide crystals- light sensitive crystals in the emulsion of film which change tone based on the amount of light they are exposed to

memory card- a small card inside of a digital camera that stores pictures, and is reusable

negatives- exposed film which can be developed and enlarged

point-and-shoot- a non-professional, amateur camera with a non-interchangeable lens and built-in flash (if any flash) which can be either digital or film

print- a final product of negatives; a positive photo on photo paper

resolution- quality of the image, determined by megapixels in digital photography

shutter- a moving piece of dark plastic or metal which covers the film until the shutter button is pressed

shutter button- moves the shutter to expose the film

shutter latency- the amount of time between when the shutter button is pressed and when the shutter actually opens fully to expose the film or CCD
