Posterizing the figure

Second week of classes are done. This week we started painting. We started with a poster study demo by Michelle on Sunday. The idea of the poster study is to study the light in the visual field. It is a planar color study. We compare the major planes existing in the entire visual field. Each note we paint we organize according to value scale that exist in the visual field.

The visual field is made up of various planes. Based on angle to source of light, each plane receives different amounts of light + surrounding tones affect a certain plane. For each plane we average the color by answering the questions below and put it down.

We work dark to light.
For each color note we put down, we answer the following questions in the order of importance.
value, chroma, hue - These three make up tone/color
Here is a picture of Michelle's demo. I must mention this is not a very good repro of the actual demo


We did 3 poster studies last week and will do 3 more this week. What I am learning is that it is very important to constantly compare, look at the whole picture and compare different areas with one another. We first identify darkest darks and lightest light. That establishes our value  scale. It is important to judge the contrast in one area to see if it reads right with the contrast in other areas. We are doing studies with different background colors and it is so interesting to see how different backgrounds affect skin tones. I am finding it a bit hard to judge shadow tones and dark lights. I can get their value right but hue and chroma is harder to judge.

In a way, poster study is one step towards likeness - how light unifies the visual field. capture light
We squint only to determine darker or lighter. It is more helpful to move eyes all around and constantly compare
The poster study teaches us the 2 important things
1. A way of looking
2. Color mixing

It teaches us about movement, structure and light.

the object that is reflecting light into shadow is more chromatic than shadow plane



The palette we are using
Raw umber - cool opaque
burnt umber - warmish
red oxide - warmest transparent

raw sienna - transparent
yellow ochre - opaque chromatic

reds - Alizarin - transparent
cad red purple - opaque chromatic
brilliant pink - opaque

2 oranges - cad orange
cad red scarlet

cad lemon

kings blue - opaque
cobalt blue - opaque
cerulean
ultramarine
violet grey
perm violet - transparent
viridian - transparent
cad green light - opaque

white is the lightest blue - adding white reduces chroma
Ivory black is the coolest darkest blue (cools and darkens)
