Copy of Line
Transcript of Copy of Line
Compare the left side to the right Thickness or Weight When creating a line you can change how hard you press with a pencil or what type of tool you use which will change how dark or light the line will be. This is used in shading to create depth. Light or Dark A line can lead the eye from place to place in a drawing or a design. The length of a line will determine or define what that line will represent in a drawing. Length Types of line zig-zag straight dotted/implied wavy LINES IN ART You will learn and practice three main types of optical illusions in your sketchbook:
- Rail Road Tracks
- Circus Tent
Once you have completed these exercises you will use your handout to come up with 2 more sketches of your own. Bridget Riley Bridget Riley Are the dots white or gray? Vasarely
analogous colors Vasarley monochromatic The term Op Art refers to Optical Art.
Op Art originated in the 1960's. It was first called “kinetic art” (art which moves) because some of the art actually moved or appeared to move because of the way the designs play tricks on our vision.
The visual effects use color and patterns that disturb the eye and cause it to see images or movement on a flat surface.
Victor Vasarely is considered the father of Op Art. Vasarely explored visual illusions, and combined geometric elements with color and value to result in optical illusions.
One of the most effective Op Art illusionists is Bridget Riley. Her work includes black and white linear work which makes her pictures appear to wave. Op Art Victor Vasarely Bridget Riley
Victor Vasarley Op Art Artist No painter, dead or alive, has ever made us more aware of our eyes than Bridget Riley.’ Robert Melville, 1971 4 Line Illusion Techniques Organic Line Illusions Central Vanishing Point Side Vanishing Point Checkerboard To create an organic line illusion begin with creating a line or shape of a natural thing. Then create radiating lines at varying distances and with different characteristics from that line. To create a side vanishing point illusion create several vanishing points directly across from one another and connect them with a type of line of your choice. To create a checkerboard illusion follow the same process but create vanishing points directly across from each other both vertically and horizontally. Then shade every other space.. Vanishing point Optical movement To create a central vanishing point make a point in the center and draw any type of line to that point. Work for Practice
-types of line
-characteristics of line Student Examples To create: Draw 25 random dots on page. Then connect to create lines and shapes. Then create radiating lines to fill page. To create: Trace the contour of your hand. Then draw radiating lines to the edge of the page. For extra practice try experimenting with characteristics of lines as well as combining techniques. Checkerboardchallenge Recreate your own version of Bridget Riley's "Movement in Squares" by following these steps. Step#1 All squares are same height... create horizontal lines 1/4 inch apart in bottom box.
Step #2 Line ruler up vertically with original image and create a vertical line in box below. **Be careful, make lines at 90 degree angle to bottom of box
Step #3 Fill every other box with dark color. Project Time Using templates (as shown above) we are going to make illusion cube sculptures Project Requirements:
-Create 3 stackable forms
-Each side of the forms should use
a different illusion or combination
-Each of the 4 illusion techniques we practiced should be used at least once
-Follow Op-Art sculpture directions for details Possible Arrangements of 3 forms LINE lines an be found in nature in such things as the veins of a leaf - the branches of a tree in winter the word line has many definitions in the dictionary. You can hit a "Line" drive in baseball, memorize lines for a play, and avoid being last in line in the cafeteria. In art the word "line" is used to describe long, thin marks, and there are many examples that fit this meaning. Lines are all around you in the world. An illusion of movement, or implied movement, caused by the response of the eye to lines, shapes and colors arranged in artworks. A point on the eye-level line, toward which parallel lines are made to recede and meet in perspective drawing. Descriptive Lines are lines that help us understand what we are seeing. Descriptive lines include outlines, contour lines, single lines, and hatching. Implied Lines lines that suggest an edge rather than clearly defining one. Implied lines occure where textures, colors, and values change at edges of shapes in artwork. Expressive Lines are lines that send us messages about what the artist wants his or her work to make us feel. Abstract lines, which are expressive, may not show us objects we recognize, but can still create a feeling in us. The use of lines - whether by a child or an artist is called descriptive. Outlines Outlines The most basic kind of descriptive line is an outline. contour lines define the outer edges of shapes.
Unlike outlines, however, contour lines vary in thickness and darkenss. They also define the edges of shapes within a form. They give a greater sense of depth to an object. Hatching thin, closely spaced, parallel lines Crosshatching Hatching lines that cross, which make a more solid shadow. in hatching the black lines are so thing a close together that they blend with the white of the paper. When this happens, they appear gray. This effect is called optical mixing - the mixing of white and black happens in the eyes. create different types of lines in each rectangle.
