Fotoshoot photography and casting glossary

ABC
Auto Backlighting Control, metering feature that automatically recognises a subject in back lighting condition and increase the exposure to compensate.

First featured in Contax (am I wrong?). Also sometimes refer as AEB (Auto Exposure Control). Auto Bracketing control: Metering feature that automatically produces three or four different exposures with one press of the shuttle release. Usually one with the recommended exposure by the camera reading, others at user specified intervals above or below the recommended setting.
Aberration
Failing in the ability of a lens to produce a true image. There are many forms of aberration and the lens designer can often correct some only by allowing others to remain. Generally, the more expensive the lens, the less its aberrations (More attention to optical quality). While no single lens is called a 'perfect lens'. The "ideal" lense would reproduce a subject in a faithful, clearly defined image on film. Aberrations, which can be divided into six basic faults, affect the Ideal performance in an optical system.

a) Spherical aberration. Basically, a beam of light passing through a lens parallel to the optical axis converges to form 3 focused image on the film. Spherical aberration is the term for an optical fault caused by the spherical form of a lense that produces different focus points along the axis for central and marginal rays.

b) Curvature of field. This optical defect causes points on an object plane perpendicular to the lens axis to focus on a curved surface rather than a plane.

c) Astigmatism. Rays of light from a single point of an object which is not on the axis of a lense fail to meet in a single focus thus causing the image of a point to be drawn out into two sharp lines, one radial to the optical axis and another perpendicular to this line, in two different planes near the curvature of field.

d) Coma. This optical defect causes the image of an off-axis point of light to appear as a comet-shaped blur of light. Coma, as well as curvature of field and astigmatism, degenerate the image forming ability of the lense at the rims of the picture.

e) Distortion. Even if the first four aberrations were totally eliminated, images could result that still have a distorted appearance. For an example, an rectangle may appear as a barrel or pin cushion-shaped object.

f) Chromatic aberration. This aberration is caused by light rays of different wavelengths coming to focus at different distances from the lense. Blue will focus at the shortest distance and red at the greatest distance. Since the natural rays of light are a mixture of colors, each aberration will give a different value corresponding to each color thus producing blurred images.
Absorption
The process by which light falling on a surface is partially absorbed by the surface.
Abstract
subjective, non-realistic image. An abstraction photograph generally contains a design of patterns or shapes where the identity of a subject is not evident.
Agitation
Keeping the developer, stop bath, or fixer in a gentle, uniform motion while processing film or paper. Agitation helps to speed and achieve even development and prevent spotting or staining.
Art Director
Artist who creates ideas and concepts for an ad or commercial, including model's poses.
Blowup
Enlargement; a print that is made larger than the negative or slide.
Collage
Composition employing various different materials combined with original artwork attached to some type of backing.
Depth of focus
Distance which the film plane can be moved while maintaining an acceptably sharp image without refocusing the lens.
Flat Lighting
Lighting that produces very little contrast or modeling on the subject and a minimum of shadows.
Implied Nude Shots
The Art of utilizing Props or Apparel to cover up Female parts which might be considered Sexual.e.g. Using a Sheer Material to cover up Breasts or Vaginal area, tho might be somewhat revealed due to the Sheerness of that material. Hope that helps to clear that up!
Latent Image
The invisible image left by the action of light on photographic film or paper. The light changes the photosensitive salts to varying degrees depending on the amount of light striking them. When processed, this latent image will become a visible image either in reversed tones (as in a negative) or in positive tones (as in a color slide).
Limiting aperture
The actual size of the aperture formed by the iris diaphragm at any setting. Determines, but usually differs from, the effective aperture.
Microprism
Minute glass or plastic structure of multiple prisms set in a viewfinder screen to act as a focusing aid. Breaks up an out-of-focus subject into a shimmer but images a focused subject clearly. Will not work satisfactorily at lens apertures smaller than f5.6.
Modeling Light
Modeling light is a light used to create a three dimensional effect achieved through the perception of form and depth.
Normal Lens
A lens that makes the image in a photograph appear in perspective similar to that of the original scene (approximately 45°). A normal lens has a shorter focal length and a wider field of view than a telephoto lens, and a longer focal length and narrower field of view than a wide-angle lens. Normal lenses corresponding to that portion of human vision in which we can discern sharp detail; technically defined as a lens whose focal length is approximately equal to the diagonal of the film frame; in 35mm photography, the diagonal measures 43mm, but in practice, lenses with focal lengths from 50mm to 60mm are considered normal.
Proof
A print with thumbnails of each photo in a set or folder. Pre 'digital' days, it was from the whole roll of film. The photographer could then choose the ones he wanted printed at a normal or enlarged size, rather than ordering a whole set of prints which used to be quite expensive. Currently, photo proofing can be done online or even on a camera display. Any means of viewing a photo before creating a final print is considered proofing.
Resolution
The ability of a lens to discern small detail; in photography, the image resolution in the final photograph depends on the resolving power of the sensitive emulsion and on that of the lens. the two are not related, but the effective resolution is a function of both; for reasonably accurate photographic measurements of lens resolution, the sensitive material must therefore have a much greater resolving power than the lens.
Signature
Display of words , letters or numerals in photo .
Super-imposed Shots
The overlay of two or more Shots via Software to be blended into one Creative Shot.
Sync speed
Exposure time with a focal-plane shutter is measured from the instant the first curtain is released, to begin its travel across the frame, until the instant the second curtain is released, to begin its travel across the frame. When the first curtain reaches the end of its travel, the film frame is uncovered as far as the first curtain is concerned, so it closes the electrical contacts for X sync and fires the flash instantly. Shutter speed at which the entire f iIm frame is exposed when the flash s fired in flash shooting. Most modern camera with vertical travel shutter curtain have faster flash sync speed like 1/250 sec. or slower, some top camera model like Nikon F5, changeable to 1/300 sec. with the Custom Setting.
TFCD
Time for CD with the best photographs from a session.
TFP
Time for Prints, also known as Trade for Prints and Test for Prints Time for print is a term used in photography to describe an arrangement between a model and a photographer (and other related professionals). Instead of paying for each others services, the photographer agrees to provide the model a certain number of prints of the best photographs from the session and a limited license to use those prints, in return for a broad model release.
