your word for today is...... "CAMERA OBSCURA" Thursday March 25th, 2010
A device used by early artists (centuries before Christ) to display a scene on the wall of an otherwise-darkened room so that it could be more-easily copied. In a manner similar to the pinhole camera, a small hole placed in an opposite wall permitted light to enter the room (the “camera”), and the scene outside became transmitted inside, and was shown inverted on the rear wall or sometimes on a screen. The camera obscura is the origin of the modern camera.
your word for today is...... "BROAD LIGHTING" Wednesday March 24th, 2010
Broad lighting occurs when the main light illuminates the side of the subject's face that is turned toward the camera.
your word for today is........ "BLUR" Tuesday March 23rd, 2010
Denotes a photograph in which movement, either camera movement, zoom lens movement or movement within the scene (e.g. a subject in motion), is recorded at a slower shutter speed than is necessary to “freeze” the motion as a sharp image. Blur is often intentionally created by a photographer who wishes to convey a sense of motion.
your word for today is......... "BULB" Monday March 22nd, 2010
A shutter speed dial setting that indicates that the shutter will remain open as long as the release button is depressed - also known as the “B setting ” or "Bulb" setting. The "B" setting is used for time exposures.
your word for today is........ APOCHROMATIC Sunday March 21st, 2010
often shortened to APO, means corrected for spherical and chromatic aberration. Lenses that are apochromatic cause all visible light wavelengths to focus on the film plane. Lenses that are not corrected for chromatic aberration tend to focus red, green and blue wavelengths on different planes.
your word for today is... "ANGLE OF INCIDENCE" Saturday March 20th, 2010
Light striking a surface is called "incident light". It becomes "reflected light" when it reflects from the surface. The "angle of incident" is the angle at which the incident light strikes the surface, and is measured from a line that is perpendicular to the surface (called the "normal").
A light meter is used to measure the "incident lighting" to determine exposure settings.
your word for today is... "AMBIENT LIGHT" Friday March 19th, 2010
Existing light surrounding a subject; the light that is illuminating a scene without any additional light supplied by the photographer. “Available light” and “existing light” are two other terms that mean the same thing.
your word for today is... "AE LOCK" Thursday March 18th, 2010
Auto Exposure Lock or "AE-L" - permits you to take an exposure meter reading from part of a scene and to keep the reading to apply it to the entire composition. The photographer first aims the camera at a specific area, takes a meter reading, locks in that reading using the camera's AE Lock, then recomposes the image and takes the picture.
your word for today is... "ABSTRACT" Wednesday March 17th, 2010
In the photographic sense, an image that is conceived apart from concrete reality, generally emphasizing lines, colors and geometrical forms, and their relationship to one another.
