Light-sensitive material equally sensitive to light of all colours of the visible spectrum.
Smooth movement of a camera, during a period incorporating the time of exposure, to keep a moving subject relatively stationary in the frame.
A camera with a wide format such as 6cm x 17cm, or equipped with a specialized scanning lens which rotates to capture a wide field of view.
The apparent change of the position or size of an image resulting from a change of viewpoint.
In general terms, the characteristics of a view or image determined by the relative positions of scene and viewer eg a tall building viewed from below appears to narrow towards the top.
Also known as a shift lens - a lens, with an image circle significantly larger than the frame, featuring elements which can be shifted sideways to bring selected parts of the image into view. It is typically used to correct converging verticals in architectural photography.
One thousand million million bytes of computer data - equivalent to one thousand Gigabytes.
A small, precision-drilled hole in a metal-foil plate used as a standard aperture in a pin-hole camera. Such holes may be created using laser cutting techniques. Also, a very small hole in a photographic emulsion or in otherwise light-proof equipment, such as bellows.
A software application integrated into a host program to provide additional menu options and extend capabilities.
Broadly, the alignment or restriction of electromagnetic radiation vibrations to a particular plane.
A unit used to measure the resolution of an image produced by an input device such as a camera or scanner. The greater the number of pixels per inch the higher the resolution of the image.
The elementary colours which, when mixed, produce all the hues in a colour space. In an additive system they are red, green and blue, and in a subtractive system they are cyan, magenta and yellow.
A basic lens of fixed focal length. By comparison with equivalent zoom lenses they incorporate less design compromise and are likely to be faster, have fewer elements, and hence reduced internal reflection and losses.
