When a centered fill strategy is used the ratio is created by overlapping the key light over the foundation of fill. A key source of equal incident intensity to the fill, overlapping the even fill, [clarification needed] will create a 2:1 reflected ratio (1 key + 1 fill over 1 fill) = 2:1. The same two equal incident strength sources placed on ...
The addition of a fourth light, the background light, makes for a four-point lighting setup. The background light is placed behind the subject(s), on a high grid, or low to the ground. Unlike the other three lights, which illuminate foreground elements like actors and props, it illuminates background elements, such as walls or outdoor scenery.
Free-Form Select (with synonyms) is a technique in printmaking, graphic design and image processing. The effect is to erase background colors or elements from a motif to create stand-alone objects. Today, this is done with graphics software (computer graphics) and computers rather than by cutting away parts with scissors or scalpels.
A second type of example relates to entirely stabilized stimuli. Their colour and lightness fade until they are no longer seen and the area fills in with the colour and lightness of the surrounding region. A famous example of fading under steady fixation is Troxler's fading. When steadily fixating on the central dot for many seconds, the ...
Clipping in some color channels may occur when an image is rendered to a different color space. When the image contains colors that fall outside the target color space, such colors are referred to as out-of-gamut. This form of clipping may be avoided by performing the color space conversion using a different rendering intent. However, this can ...
Many color gels organized, some in gel heads. A color gel or color filter (Commonwealth spelling: colour gel or colour filter), also known as lighting gel or simply gel, is a transparent colored material that is used in theater, event production, photography, videography and cinematography to color light and for color correction.

In archaeology a fill is the material that has accumulated or has been deposited into a cut feature such as ditch or pit of some kind of a later date than the feature itself. [1] Fills are an important part of the archaeological record as their formation and composition can throw light on many aspects of archaeological study.
The advantage of using a fill flash located near the lens axis is "normalizing" exposure in situations like backlighting which exceed the ability of the camera to handle the contrast of the lighting. The disadvantage is the same one seen in indoor near-axis flash shots; a lack of directional modeling clues.
