CMT 11 Photography Terms Assignment
Definitions:
1. Aperture- A space through which light passes in an optical or photographic instrument, especially the variable opening by which light enters a camera.
2. Dept of field- The distance between the nearest and the furthest objects that give an image judged to be in focus in a camera.
3. Darkroom- A darkroom is a room that can be made completely dark to allow the processing of light sensitive photographic materials.
4. Developer-photographic developer (or just developer) is a chemical that makes the latent image on the film or print visible. It does this by reducing the silver halides that have been exposed to light to elemental silver in the gelatine matrix.
5. Enlargement- A photographic print in which the scale of an object is larger than the same object in the negative. If the entire negative frame is printed the print is larger than the frame.
6. F-stop- The f-stop number is a ratio of the focal length of the lens to the diameter of the aperture. A lens is said to be "wide open" when it's set on its smallest f-stop, or with the aperture opened as wide as possible.
7. Fixer- fixer is a mix of chemicals used in the final step in the photographic processing of film or paper.
8. ISO- ISO measures the sensitivity of the image sensor. The same principles apply as in film photography the lower the number the less sensitive your camera is to light and the finer the grain. 9. Panning- panning refers to the rotation in a horizontal plane of a still camera or video camera. Panning a camera results in a motion similar to that of someone shaking their head "no" or of an aircraft performing a yaw rotation
10. Single-lens reflex camera (SLR)- A single-lens reflex (SLR) camera is a camera that typically uses a mirror and prism system that permits the photographer to view through the lens and see exactly what will be captured, contrary to viewfinder cameras where the image could be significantly different from what will be captured.
11. Stop
12. Telephoto lens- A telephoto lens is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length.
13. View camera- It comprises a flexible bellows which forms a light-tight seal between two adjustable standards, one of which holds a lens, and the other a viewfinder or a photographic film holder
14.Viewfinder camera- A viewfinder is what the photographer looks through to compose, and in many cases to focus, the picture. Most viewfinders are separate, and suffer parallax, while the single-lens reflex camera lets the viewfinder use the main optical system.
15. Zoom lens- A zoom lens is a mechanical assembly of lens elements for which the focal length can be varied, as opposed to a fixed focal length lens.
16. Continuous tone photography- A continuous tone image is one where each color at any point in the image is reproduced as a single tone, and not as discrete halftones, such as one single color for monochromatic prints, or a combination of halftones for color prints.
17. Lens- is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
18.
19. Wide-angle lens- Telephoto lens-a wide-angle lens refers to a lens whose focal length is substantially smaller than the focal length of a normal lens for a given film plane. This type of lens allows more of the scene to be included in the photograph, which is useful in architectural, interior and landscape photography where the photographer may not be able to move farther from the scene to photograph it.
20. Shutter- a shutter is a device that allows light to pass for a determined period of time, for the purpose of exposing photographic film or a light-sensitive electronic sensor to light to capture a permanent image of a scene.
