E-6

Definition: Chemical processing system for most colour-reversal (slide) film.

E6

Definition: Kodak's standard chemical process for developing Ektachrome or compatible slide films.

EASEL

Definition: A holder to keep sensitized material, normally paper flat and in position on the baseboard of an enlarger during projection printing. It usually has adjustable borders to frame the image to various size.

Definition: A device to hold photographic paper flat during exposure, usually equipped with an adjustable metal mask for framing.

EASEL (MASKING FRAME)

Definition: A holder to keep sensitized material, normally paper, flat and in position on the baseboard of an enlarger during projection printing. It usually has adjustable borders to frame the image to various sizes.

EBERHARD EFFECT

Definition: border effect occurring in a developed image. It appears as a dense line along an edge of high density and as a light line along an edge of low density. It occurs most often in plates developed flat in solution that is not sufficiently agitated. The effect was described by Gistav Eberhard in 1926.

ECG TECHNOLOGY ENHANCED CUBIC GRAIN

Definition: A technology that provides amplified sharpness in Kodak Advantix 100-speed film.

EDGE NUMBERS

Definition: The reference numbers printed by light at regular intervals along the edge of 35mm and roll films during manufacture.

EFFECTIVE APERTURE

Definition: diameter of the bundle of light rays striking the first lens element that actually pass through the lens at any given diaphragm setting.

EFFECTIVE RESOLUTION

Definition: The final appearance of a scan that has been enhanced to produce more data than the scanner can record. This is done by interpolation.

EI

Definition: see exposure index

EIS

Definition: Electronic Image Stabilizer. A feature that minimizes effect of camera shake.

EISA BUS

Definition: Eisa is a standard bus ( computer interconnection ) architecture that extends the ISA standard to a 32-bit interface.

ELECTRICAL

Definition: The electrical performance of the tape samples is measured and compared to the VHS-standard reference tape (the JVC VRT-2). The published numbers represent how much better (+) or worse (-) then the industry standard tape each tape sample performed (the JVC VRT-2 scores 0. 0 for every parameter).

ELECTROLUMINESCENCE

Definition: conversion of electric energy directly into visible light.

ELECTROMAGNETIC SPECTRUM

Definition: The forms of radiant energy arranged by size of wavelength ranging from billionths of a millimeter (gamma rays) to several miles (radio waves). The visible spectrum is the part that the human eye sees as light: wavelengths of 400 to 700 nanometers (billionths of a meter) producing the sensation of the colors violet, blue green, yellow, and red.

ELECTRONIC DISPLAY

Definition: Showing images through the computer.

ELECTRONIC DOCUMENT

Definition: A document that has been scanned, or was originally created on a computer. Documents become more useful when stored electronically because they can be widely distributed instantly, and allow searching. HTML and PDF are well known electronic document formats

ELECTRONIC FLASH

Definition: A tube containing gas that produces a brief, brilliant flash of light when electrified. Unlike a flashbulb, an electronic flash unit is reusable. Also called a strobe.

Definition: artificial lighting produced by an electronic discharge in a gas filled tube. A single tube can produce a large number of flashes.

Definition: A small device usually built into digital cameras that emits a brief burst of light to illuminate poorly lit scenes.

ELECTRONIC MEDIA

Definition: Any of the media used to publish information electronically (as opposed to print). Some examples are: presentation packages, annotated image catalogues, World Wide Web pages.

ELECTRONIC PUBLISHING

Definition: Composition of text (and frequently graphic images) using a computer for display in a computer presentation program or on the World Wide Web.
