Chapter 7
Pointillism AKA neoimpresialism (the paintings)
The different color dots blend in because they are small. The size of the dots matter, so how
close or far away you are matters (optimal distance) Luminance is homogeneous the receptive
cell is larger in the are (where the sky is) and that’s why is looks blue.
Illusionary Borders
● Most people see a bluish circle in the middle-
○ But there is no circle
● Illusionary border
○ You perceive a border when none is present
○ Usually most salient when the colors share luminance
Illusionary Conjunction- When binding two physical objects into one.
Why is pointillism special?
● All dots on any given are close to the same luminance
● The borders that define objects are illiosinary borders
When will colors blend? (asking a question about this)
● The form system (the what system)- defines the borders
● A lower resolution system assigns color
● Whether or not color blend seems to depend on whether they can be perceived as
belonging to the same surface
● When the luminance is the same - the system assumes a similar surface
● When it differs- the system assumes different surface
Chuck Close (local vs global luminance)
● Uses huge elements (*compared to the pointillists)
● Blends resolution
● Blending is best when colors are close to the same luminance
○ Perceived as part of the same surface
○ Colors bleed until they hit an illusionary border
○ Look at the forehead-
○ The colors all pale, equiluminant, and blend
○ Also because of the difference between the visual system
■ You see something new every time you shift your gaze
Robert Silvers
● Creates images using other images
● Using a computer
● He matches the local luminance and color of each region of the “target”
○ With the luminance & color of many small images
● The computer assembles the image with high resolution for both the small & large
images
