Liquid-Crystal Display. An electronically generated text or symbol display commonly found on 35mm and video cameras
LD: :
Low dispersion. See Extra-low Dispersion.
LEAF SHUTTER: :
See Also: Lens Shutter
LED: :
Light-Emitting Diode. Small, light-producing transistor commonly used in viewfinder and other information displays.
LENS SHUTTER: :
Iris-like device made of interleaved metal blades. Usually positioned within a lens. Controls the amount of light used to expose film. See also: Focal Plane Shutter, Leaf Shutter. Most point & shoot cameras are lens-shutter cameras. A lens-shutter camera has two lenses—one for viewing the scene and one for taking the picture. This means that what you see in the viewfinder is only an approximation of what you'll
end up with on film.
LENS SPEED: :
Refers the a lens’s ability to transmit light. Fast lenses transmit more light than slow lenses. Lens speed is calibrated in f-stops. Lower numbers (f/1.8, f/2.0) indicate faster lenses. Speed is a desirable quality because it allows the photographer to shoot in relatively low light
LOSSY FORMAT: :
When a digital image is compressed to save file space, quality can sometimes be lost forever. A compression method that causes lost data is called "lossy". Once data has been lost in a lossy compression, it's gone forever—unless you have a copy of the original, uncompressed version hidden away somewhere. No amount of decompression will bring back this lost data, although artifact problems can sometimes be corrected with painstaking photo correction
