Elinchrom supplies a range of lighting modifiers as accessories for their lights. Some accessories (such as umbrellas) attach to the light unit by means of a pole passing through a 7 mm hole through the head, and others (such as softboxes, reflector dishes and snoots) attach using Elinchrom's bayonet system.
A softbox can be used with either flash or continuous light sources such as fluorescent lamps or "hot lights" such as quartz halogen bulbs or tungsten bulbs. If softbox lights are used with "hot" light sources, the photographer must be sure the softbox is heat rated for the wattage of the light to which it is attached in order to avoid fire hazard.
A scrim is a device used in the film and television industries, as well as by photographers, to modify properties of light. There are variations on types of scrim, depending upon its use, whether with natural light, or with man-made light sources. However, their basic use is the same – to reduce intensity and/or harshness of light.
As well as dedicated studio use, flash may be used as the main light source where ambient light is inadequate, or as a supplementary source in more complex lighting situations. Basic flash lighting produces a hard, frontal light unless modified in some way. [22] Several techniques are used to soften light from the flash or provide other effects.

Photographic processing transforms the latent image into a visible image, makes this permanent and renders it insensitive to light. [1] All processes based upon the gelatin silver process are similar, regardless of the film or paper's manufacturer. Exceptional variations include instant films such as those made by Polaroid and thermally ...
In a scene with strong or harsh lighting, the ratio between highlight and shadow luminance values may well be larger than the ratio between the film's maximum and minimum useful exposure values. In this case, adjusting the camera's exposure settings (which only applies changes to the whole image, not selectively to parts of the image) only ...
The light sensitive layer or emulsion consists of silver halide crystals in a gelatin base. Two photons of light must be absorbed by one silver halide crystal to form a stable two atom silver metal crystal. The developer used generally will only reduce silver halide crystals that have an existing silver crystal.
