Contrast sensitivity is typically expressed as the reciprocal of the threshold contrast for detection of a given pattern (i.e., 1 ÷ contrast threshold). [16] Using the results of a contrast sensitivity exam, a contrast sensitivity curve can be plotted, with spatial frequency on the horizontal, and contrast threshold on the vertical axis.
Both processes affect the resulting color mixture's relative saturation. A tone is produced either by mixing a color with gray , or by both tinting and shading. [ 1 ] Mixing a color with any neutral color (including black, gray, and white) reduces the chroma , or colorfulness , while the hue (the relative mixture of red, green, blue, etc ...
Port with the disembarkation of Cleopatra in Tarsus (1642), by Claude Lorrain, Musée du Louvre, Paris. Light in painting fulfills several objectives like, both plastic and aesthetic: on the one hand, it is a fundamental factor in the technical representation of the work, since its presence determines the vision of the projected image, as it affects certain values such as color, texture and ...
The difference in values is often called contrast, and references the lightest (white) and darkest (black) tones of a work of art, with an infinite number of grey variants in between. [6] While it is most relative to the greyscale, though, it is also exemplified within colored images.
Various attributes of an image such as contrast, color, saturation, detail, black level, and white balance may be enhanced whether for motion pictures, videos, or still images. Color grading and color correction are often used synonymously as terms for this process and can include the generation of artistic color effects through creative ...

Fig. 1. HSL (a–d) and HSV (e–h). Above (a, e): cut-away 3D models of each. Below: two-dimensional plots showing two of a model's three parameters at once, holding the other constant: cylindrical shells (b, f) of constant saturation, in this case the outside surface of each cylinder; horizontal cross-sections (c, g) of constant HSL lightness or HSV value, in this case the slices halfway ...
(See Contrast (vision)) Few editors other than Photoshop implement this same color space for their analogs of these blend modes. [3] Instead, they typically base their blend modes on HSV (aka HSB) or HSL. Blend modes based on HSV are typically labeled hue, saturation, and brightness. Using HSL or HSV has the advantage that most operations ...
