Agitation – Gently moving developing chemicals to evenly process film or photographic prints.
Aperture – The aperture stop of a photographic lens can be adjusted to control the amount of light reaching the film or image sensor. In combination with variation of shutter speed, the aperture size will regulate the film's or image sensor's degree of exposure to light.
Aperture Priority – Often abbreviated A or Av (for aperture value) on a camera mode dial, is a setting on some cameras that allows the user to choose a specific aperture value while the camera selects a shutter speed to match.
ASA – American Standards Association is a now defunct rating system for film speed. The ASA system has been replaced by the universal ISO system. However, it is still a commonly used term.
Auto Exposure (AE) – The aperture and shutter speed are automatically determined for exposure.
Auto Focus (AF) – The ability of a camera lens to automatically find a point of focus.
Bellows – The pleated expandable part of a camera, usually a large or medium format camera, to allow the lens to be moved with respect to the focal plane for focusing.
Black and White (B&W) – A term referring to a number of monochrome forms in photography.

Color Reversal – Color film that shows the actual color on film. This film cannot be printed through common darkroom techniques as it requires a negative to positive, but can be shown through a slide projector.
Composition – Putting together various visual elements to create a unique organization or grouping to achieve a unified image or photograph.
Contact Print – A photographic image produced from film; sometimes from a film negative, and sometimes from a film positive. The defining characteristic of a contact print is that the photographic result is made by exposing through the film negative or positive, onto a light sensitive material that is pressed tightly to the film.
Contact Sheet – A set of multiple images printed at the same size as the negative, on one page. In film photography, contact sheets were often used to quickly scan for the highest quality images from a roll of film.
Contrast – The relative difference between light and dark areas of the photograph.
Crop – Enlarging a photography to purposely cut-off certain edges of an image when printing negatives.
Cross Processing (or Xpro) – The deliberate processing of photographic film in a chemical solution intended for a different type of film. The effect was discovered independently by many different photographers often by mistake. Color cross processed photographs are often characterized by unnatural colors and high contrast.

Developer – The chemical that removes the first layer of emulsion from film or photographic paper and allows the image to be seen.
Developing Tank – A light-tight container used for developing film. A developing tank allows photographic film to be developed in a daylight environment. This is useful because most film is panchromatic and therefore can not be exposed to any light during processing. Depending upon the size and type, a developing tank can hold one to many roll or sheet films.
Dodging – Blocking light from an area of the photographic print to lessen the amount of exposure and lighten that particular spot.
Double Exposure – Exposing film twice allowing for two similar or different images to overlap on a single negative.

Lens Speed – The widest aperture setting possible for a camera lens. A fast speed also allows for faster shutter speed settings.
Light Leak – A hole or gap in the body of a camera where light is able to "leak" into the normally light-tight chamber, exposing the film or sensor with extra light. This light is diffuse, although parts within the camera may cast shadows or reflect it in a particular way. For most purposes this is considered a problem. Within the lomography movement it is seen as a positive effect, giving photos character.

Negative – Film that is developed and shows the opposite of a printed image. In black and white photography, white on the negative will print black and black will print white.
Overexposure – An image that receives too much light for an exposure. Overexposed images are bright, often with a complete loss of detail and contrast in the highlights.
Panning – Using a slow shutter speed and tracking the movement of the subject with the camera lens. If done successfully, the background will have motion blur while the subject appears to be in clear focus.
Parallax Error – An instance where the camera lens and viewfinder do not see the exact same frame, causing the photographer to compensate for the offset. Close-up photography suffers heavily from the parallax error as it makes it difficult to compensate and focus correctly. Problematic for viewfinder cameras or twin-lens reflex cameras.
Pinhole Camera – A simple camera without a lens and with a single small aperture, a pinhole – effectively a light-proof box with a small hole in one side. Light from a scene passes through this single point and projects an inverted image on the opposite side of the box.

Safelight – Lights found in a darkroom that will not expose light sensitive materials. Film cannot be exposed to any light before development, not even safelights.
Self-Timer – A feature on many cameras that allows the user around 10-seconds before the shot is taken. This is typically used in shots that involve the photographer.
Shutter – Blocks light from traveling through the lens and exposing film until it is opened during exposure. Shutters can be made of blades, a curtain, plate, or other movable covers and control the amount of time light is allowed through the lens.
Shutter Priority – An automatic setting that will automatically change the aperture depending on the chosen shutter speed.
Shutter Speed – How fast or slow the shutter opens and closes to expose the film behind the lens. Plays a pivotal role in motion photography.
Single-Lens Reflex (SLR) – A camera with a single lens that is used for viewing and capturing the image. The image is reflected with a moveable mirror in the camera body that allows the photographer to see directly through the lens. The mirror flips up when the shutter is opened to allow light to expose the film.
Slide Film – Film that when processed shows a positive image. Also known as “reversal film” or “transparency film.”
Snapshot – An image captured informally, usually with a disposal or quick shot camera.

Twin Lens Reflex (TLR) - A camera having two separate lenses of the same focal length – one for viewing and focusing; the other for exposing the film. The lenses are mechanically-coupled so that both are focused at the same time.
Underexposure – An image that does not receive enough light for a proper exposure. Underexposed images are dark, often with a complete loss of detail and contrast.
View Camera – A type of large format camera that typically uses negatives sized 5” x 7” or 8” x 10”. These cameras offer the most control of any camera type.
Viewfinder – The viewing device on the camera that allows the photographer to see the approximate or exact view of the camera’s lens. Only single-lens reflex cameras give the user the ability to see exactly what the camera sees.
