Position on the format:
-Objects placed at the bottom of the page appear closer than objects at the top of the page.
-Smaller objects appear further away from the larger objects.
-Objects in the distance have less detail and fewer colours than those on the foreground.
-Objects with interrupted edges appear to be further away than those with complete contours.
-The object we see through the glass appears further away.
-Uses vanishing points to create the illusion. Parallel perspective has one VP (vanishing point).
Artists use a combination of devices to create the illusion of depth on a two dimensional surface. Photographs help solve perspective problems and can be by artists to improve.
Still life drawing:
-Draw a horizon line (just above the middle of your paper).
-Use very light outlines to place your objects (you may need to erase).
-It may be helpful to draw objects closer to you first.
What is perspective?
Perspective is a mathematical system.
One point perspective:
-The sides of an object diminish toward the vanishing point. All vertical and horizontal lines though are drawn with no perspective.
The vanishing point is generally placed at the viewer’s eye level as well.
Straight lines (diagonal) drawn to connect points around the edges of a picture to the vanishing point.
Putting it together:
Horizontal and vertical lines are then inserted to create a three dimensional box. The sides of the box can also be coloured with different shades to indicate the depth of the object.
Two point perspective
In two point perspective, the sides of an object vanish to one of two vanishing points on the horizon.
The horizon line represents the line in nature where earth and sky appears to meet the ground. The placement of this line on the picture plane will change how the viewer sees the picture.
Single points in a picture where all parallel lines that run from the viewer to the horizon line appear to come together. In two point perspective, these points are sometimes so far apart that they are off of the paper. The vertical line in the middle will be used to construct a box.
Straight diagonal lines drawn to connect points around the edges of a picture to the vanishing point. They represent parallel lines receding into the distance and help draw the viewer’s eye into the depth of the picture.
The horizon line:
In perspective, the horizon is an imaginary line drawn across the picture plane at the viewer’s eye level.
Vertical lines are then inserted to create a three dimensional box. Due to the placement of the horizon line and the corner of the box, we are not able to see the top of the box.
