Composition/Unity Flashcards
In perspective, what is ground plane?
The horizontal plane where the artist is standing.
In perspective, what is the center of vision?
The point on the horizon immediately opposite the eye
In perspective, what is the vanishing point?
That is where parallel lines converge.
What is plane linear perspective?
When Objects closer to the point of site appear bigger than those which are further away
What is the point of site?
The position from which an object is seen and drone is called the station point or point of sight
What is angular perspective?
Placement which causes two faces of an object to be oblique to the picture plane; parallel lines converge on two vanishing points on the horizon.
What is three point oblique perspective?
Placement which causes three faces of an object to be oblique to the picture plane and parallel lines converge on two vanishing points on the horizon.
What is curvilinear perspective?
Made on a curved rather than flat picture plane
Cylindrical or panorama perspective?
Shows a picture like a panorama; the Picture plane itself may be a cylinder
Spherical perspective?
Projection onto a spherical Picture plane; similar to the effects created by a wide angle lens photograph where lines appear to be curved.
What are the two basic categories of perspective?
Aerial: refers to atmospheric effects on objects in space and can be seen as diminishing tones for objects which are receding from view.
Linear: describes the process of seeing lines on objects from various angles converge and diverge. The position from which an object is seen and drawn is called the station point or point of sight.
Use of line:
Line is fundamental to the expression of movement and mass. Motion is almost always expressed by line, through repetition, convergent planes, in three-dimensional volume or mass.
Use of line: what are the three main groups of lines?
Contour, calligraphic, and tonal.
Contour: drawing the outline of a subject.
Calligraphic: capturing emotion and expression through the use of line.
Tonal: using gradations in line shading.
Use of tone:
Is a representation of shifting variable qualities of light through intensity and direction of flow. Can indicate passage from light to deep shadow in areas of one color. It is useful in monochrome work. In representational painting, tone is essential in creating the illusion of form, space and depth.
Use of color
Color choices maybe used to balance compositions so that the eye is not drawn to anyone element or area, for building indeterminate forms like water colored renditions of clouds, to render sharply defined forms through adjacent contrasting colors, to convey a mood, to control light and shadow.
Spatial depth can be described by…
Advancing and receding color (warmer colors used to indicate close proximity and cooler colors indicate farther away), diminishing detail (less detail on items farther away), overlapping planes (near figures interposed over those further back), position in the picture plane (items closer towards the bottom of the picture), aerial perspective of color (items farther away are paler and less distinct), convergent diagonals, and transparency.
