Photographic lighting refers to how a light source, artificial or natural, illuminates the scene or subject that is photographed; put simply, it is lighting in regards to photography. Photographers can manipulate the positioning and the quality of a light source to create visual effects , potentially changing aspects of the photograph such as ...
This effect usually hides details, causes a stronger contrast between light and dark, creates silhouettes and emphasizes lines and shapes. The sun , or other light source, is often seen as either a bright spot or as a strong glare behind the subject. [ 1 ]
A latent image is formed when light changes the charge atoms in the molecule. Taking bromine as a halide for this example, when light hits a silver halide molecule, the halide is changed from a negative charge to a neutral one, releasing an electron that then changes the charge of the silver from a positive one to a neutral one.

A simple, idealized statistical model yields the equation density = 1 – ( 1 – k) light, where light is proportional to the number of photons hitting a unit area of film, k is the probability of a single photon striking a grain (based on the size of the grains and how closely spaced they are), and density is the proportion of grains that ...
The drawing on the upper right shows a moiré pattern. The lines could represent fibers in moiré silk, or lines drawn on paper or on a computer screen. The nonlinear interaction of the optical patterns of lines creates a real and visible pattern of roughly parallel dark and light bands, the moiré pattern, superimposed on the lines. [4]
Light trails are another photographic effect where motion blur is used. Photographs of the lines of light visible in long exposure photos of roads at night are one example of the effect. [12] This is caused by the cars moving along the road during the exposure. The same principle is used to create star trail photographs.
Light painting inside an abandoned limestone quarry in France. Light painting, painting with light, light drawing, light art performance photography, or sometimes also freezelight are terms that describe photographic techniques of moving a light source while taking a long-exposure photograph, either to illuminate a subject or space, or to shine light at the camera to 'draw', or by moving the ...
Pseudo-solarisation (or pseudo-solarization) is a phenomenon in photography in which the image recorded on a negative or on a photographic print is wholly or partially reversed in tone. Dark areas appear light or light areas appear dark. The term is synonymous with the Sabattier-effect when referring to negatives. Solarisation and pseudo ...
