The use of negative space is a key element of artistic composition. The Japanese word "ma" is sometimes used for this concept, for example in garden design. [2] [3] [4] In a composition, the positive space has the more visual weight while the surrounding space - that is less visually important is seen as the negative space.
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens. It is widely used in optical engineering laboratory work to analyze and ...
Lightning is a natural phenomenon formed by electrostatic discharges through the atmosphere between two electrically charged regions, either both in the atmosphere or one in the atmosphere and one on the ground, temporarily neutralizing these in a near-instantaneous release of an average of between 200 megajoules and 7 gigajoules of energy, depending on the type.
Positive space is the idea that any part of a photo that includes the subject, stands out from the rest of the photo. It is key component in most photographs that helps convey emotions towards an audience. The technique can illustrate emotions ranging from crowdedness, to power, to chaos, or even to movement in a photo.
Negative curvature – a drawn triangle's angles add up to less than 180°; such 3-dimensional space is locally modeled by a region of a hyperbolic space H 3. Curved geometries are in the domain of non-Euclidean geometry. An example of a positively curved space would be the surface of a sphere such as the Earth.
YCbCr, Y′CbCr, or Y Pb/Cb Pr/Cr, also written as YCBCR or Y′CBCR, is a family of color spaces used as a part of the color image pipeline in video and digital photography systems. Y′ is the luma component and C B and C R are the blue-difference and red-difference chroma components. Y′ (with prime) is distinguished from Y, which is ...
The method of image charges (also known as the method of images and method of mirror charges) is a basic problem-solving tool in electrostatics.The name originates from the replacement of certain elements in the original layout with fictitious charges, which replicates the boundary conditions of the problem (see Dirichlet boundary conditions or Neumann boundary conditions).
Calotype or talbotype is an early photographic process introduced in 1841 by William Henry Fox Talbot, [ 1 ] using paper [ 2 ] coated with silver iodide. Paper texture effects in calotype photography limit the ability of this early process to record low contrast details and textures. The term calotype comes from the Ancient Greek καλός ...
