A Glossary of Photographic Terms: E
- A device to hold photographic paper flat during exposure, usually equipped with an adjustable metal mask for framing.
- ECG technology Enhanced Cubic Grain
- A technology that provides amplified sharpness in Kodak Advantix 100-speed film.
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).
- Micro-thin layers of gelatin on film in which light-sensitive ingredients are suspended; triggered by light to create a chemical reaction resulting in a photographic image.
- Emulsion Side
- The side of the film coated with emulsion. In contact printing and enlarging, the emulsion side of the film-dull side-should face the emulsion side of the photo paper-shiny side.
- Enhanced Back-Printing
- An Advanced Photo System feature available in some system cameras that enables users to encode detailed information at the time of picture-taking, such as the date and time of exposure, camera settings, roll title or other custom information for subsequent printing onto the back of their photographs. See also Back-printing.
- A print that is larger than the negative or slide; blowup.
- A device consisting of a light source, a negative holder, and a lens, and means of adjusting these to project an enlarged image from a negative onto a sheet of photographic paper.
- Existing Light
- Available light. Strictly speaking, existing light covers all natural lighting from moonlight to sunshine. For photographic purposes, existing light is the light that is already on the scene or project and includes room lamps, fluorescent lamps, spotlights, neon signs, candles, daylight through windows, outdoor scenes at twilight or in moonlight, and scenes artificially illuminated after dark.

- The quantity of light allowed to act on a photographic material; a product of the intensity (controlled by the lens opening) and the duration (controlled by the shutter speed or enlarging time) of light striking the film or paper.
- Exposure Latitude
- The range of camera exposures from underexposure to overexposure that will produce acceptable pictures from a specific film.
- Exposure Meter
- An instrument with a light-sensitive cell that measures the light reflected from or falling on a subject, used as an aid for selecting the exposure setting. The same as a light meter.
- Extra High Grade
- A truly high grade tape will demonstrate its differences mostly in the quality of the image recorded. Extra high grade tape coatings are generally superior in noise immunity and lower in dropouts. This means that you get a better recording, and you'll get a better second and third generation copy. Several manufacturers have indicated on their packaging that they have done things to also provide greater longevity, but this is a claim that would be difficult to prove or disprove. For especially valuable recordings, use a high grade tape; but remember that there is no standardization and no requirements that prevent anyone from naming a product "extra high grade." Buy a tape with a brand you trust.
