Namjoon
An S-shaped graph that serves as a "snapshot" of a given film's reaction to light. It shows the relationship between exposure and density increase.
What is the characteristic curve
An individual digital image that can be stored, transferred, or manipulated
What is an image file
A measure of how rapidly image files can be transferred from the camera to the memory card.
What is card speed.
The amount of light reflected from a scene that reaches the camera's image receiver.
What is exposure
A book or binder displaying a photographer's best work; used to display the photographer's skills and abilities to potential clients or employers.
What is a portfolio.
The common form of subtractive color film, consisting of THREE separate emulsion layers. One is sensitive to blue light, another to red light, and the third to green light.
What is integral tri-pack film?
A numeric expression of the number of shades of gray a pixel is capable of displaying.
What is bit depth?
Internal memory in a camera that functions as a "holding tank" for image information already processed but not yet transferred to the memory card.
What is a buffer?
Term describing a device, such as a memory card, that has NO MOVING parts.
What is solid-state?
Professional photographers who make all or most of their living from photographic work.
What are commercial photographers
The bottommost layer of film, located on the back side of the base. This layer prevents light rays from being reflected back through the base and emulsion.
What is the antihalation layer?
Image formation that is encoded as a series of on/off states (usually represented by 1 and 0) rather than varying continuously.
What is a digital signal?
A color film that results in a reversed or positive final image (transparency or slide).
What is reversal film?
File that contains the basic image information captured by the camera's sensor and is saved with minimal processing.
What is RAW?
A legal document that specifies the responsibilities of both the photographers and client and spells out every detail of the arrangement.
What is a contract?
Impurities believed to play the important role of focal points or sites for the formation of the silver clumps making up the latent (undeveloped) photographic image.
The very thin, tough topmost layer of black-and-white film. Its primary purpose is to protect the emulsion from abrasion during exposure and processing.
What is supercoat?
The darkness, or light-blocking ability, of a developed photographic image.
What is density?
A very thin coating of pure gelatin that helps bond the emulsion to the base in black-and-white film.
What is subbing layer?
A numerical designation indicating the light sensitivity of film, with higher numbers indicating greater sensitivity.
What is ISO rating?
A film's sensitivity to light.
What is film speed?
Different modes of saving image data (i.e. JPEG or TIFF).
What are file formats?
The built-in program found in a digital camera or similar device.
What is firmware?
Atoms carrying a positive or negative electrical charge.
What are ions?
Tiny light-colored spots especially noticeable in shadow of areas of an image. Also know as "grit".
What is digital noise?
