A curve showing the relationship between exposure and resulting density in a photographic image, usually plotted as the density (D) against the logarithm of the exposure (log E) in candlemeter-seconds. It is also called the H and D curve, the sensitometric curve, and the D log E curve.
(electronics) graph showing how a particular characteristic of a device varies with other parameters
a graphic representation of the response of a film to both exposure and development
a graph of the relationship between the amount of exposure given a film and its corresponding density after processing
This graphically illustrates the performance of a film. The graph shows the relationship between the film's exposure to light and its developed density under known developing conditions. The curve gives you information on factors such as emulsion speed, fog level, and the film's contrast. The slope of the curve of the characteristic line is called Gamma. This is also the tangent of the line at any point.
A curve, which D is plotted against Log E resulting from photographic plates exposed to a constant light I (power intensity) for a series of time(time-scale exposures).
A curve (of a film) showing the relationship between the common logarithm of exposure, log K, and the optical density, D. Also called the D-log E curve or the H and D curve.
Shows the relationship between the exposure of a photographic material and the image density produced after processing.
1. A graph (curve) which shows the ideal values at steady state or an output variable of a system as a function of an input variable, the other input variables being maintained at specified constant values.
performance graph showing the relationship between exposure and density under known developing conditions. It can provide immediate comparative information on factors such as emulsion speed, fog level, and contrast effect. The study of photographic chemicals in this way is known as sensitometry.
