In painting, photography, graphical perspective and descriptive geometry, a picture plane is an image plane located between the "eye point" (or oculus) and the object being viewed and is usually coextensive to the material surface of the work. It is ordinarily a vertical plane perpendicular to the sightline to the object of interest.
Stylisation can lead to the fully abstract picture, where reference is only to conditions for a picture plane – a severe exercise in self-reference and ultimately a sub-set of pattern. But just how pictures function remains controversial. Philosophers, art historians and critics, perceptual psychologists and other researchers in the arts and ...
If one makes the analogy of taking a photograph to rendering a 3D image, the surface of the film is the image plane. In this case, the viewing transformation is a projection that maps the world onto the image plane. A rectangular region of this plane, called the viewing window or viewport, maps to the monitor.
Cyfeilliog (died c. 927) was a bishop in south-east Wales.The location and extent of his diocese is uncertain, but lands granted to him are mainly close to Caerwent, suggesting that his diocese covered Gwent, possibly extending into Ergyng (now south-west Herefordshire).
A picture plane in perspective drawing is a type of projection plane. With perspective drawing, the lines of sight, or projection lines, between an object and a picture plane return to a vanishing point and are not parallel. With parallel projection the lines of sight from the object to the projection plane are parallel.
Perspective distortion (photography), the way that viewing a picture from the wrong position gives a perceived distortion Perspective (geometry) , a relation between geometric figures Vue d'optique or perspective view, a genre of etching popular during the second half of the 18th century and into the 19th.
The points in focus (2) project points onto the image plane (5), but points at different distances (1 and 3) project blurred images, or circles of confusion. Decreasing the aperture size (4) reduces the size of the blur spots for points not in the focused plane, so that the blurring is imperceptible, and all points are within the DOF.
