Panning
Moving the camera so that the image of a moving object remains in the same relative position in the viewfinder as you take a picture.
Panorama
A broad view, usually scenic.
Parallax
With a lens-shutter camera, parallax is the difference between what the viewfinder sees and what the camera records, especially at close distances. This is caused by the separation between the viewfinder and the picture-taking lens. There is no parallax with single-lens-reflex cameras because when you look through the viewfinder, you are viewing the subject through the picture-taking lens.
Polarizing Screen (Filter)
A filter that transmits light traveling in one plane while absorbing light traveling in other planes. When placed on a camera lens or on light sources, it can eliminate undesirable reflections from a subject such as water, glass, or other objects with shiny surfaces. This filter also darkens blue sky.
Positive
The opposite of a negative, an image with the same tonal relationships as those in the original scenes-for example, a finished print or a slide.
Print
A positive picture, usually on paper, and usually produced from a negative.
Printing Frame
A device used for contact printing that holds a negative against the photographic paper. The paper is exposed by light from an external light source.
Printing-in
(See Burning-in)
Processing
Developing, fixing, and washing exposed photographic film or paper to produce either a negative image or a positive image.
Program Exposure
An exposure mode on an automatic or autofocus camera that automatically sets both the aperture and the shutter speed for proper exposure.
Projected Frame
(See Finder)
Push Processing
Increasing the development time of a film to increase its effective speed (raising the ISO number for initial exposure ) for low-light situations; forced development.
