Lighting and Color for Reference and Drawing

Floating cube have six-sided shadows.

The lighting on the moon reveals the lighting on objects.

It is whiter near the horizon due to particles riled by the wind.

The ocean absorbs red. It doesn't scatter red.

Rain is only apparent against a dark background. Each drop reflects the sky.

Refer to albedo chart for reflective percentage.

Shadow will always dominate pattern.

The entire sky is a light source due to the atmosphere. The moon has no atmosphere and therefore the shadows there are pitch black.

Rayleigh scattering scatters the blue wavelength on a short scale. It scatters red eventually and that's why the sunset appear red since the viewer looks through so much atmosphere.

Mie scattering scatter white and it deals with larger particles while rayleigh deals with smaller.

When blue scatters, it causes the air to illuminate as blue light.

Cones in eyes turn off at night and things appear as black and white.

Looking straight up at the sky (90 degrees), that's considered as looking through 1 atmosphere.
Looking 30 degrees above the horizon is 2 atmosphere.
10 degree is 5.7.
5 is 10.8
0 is 45.

At 0 degree, all light is scattered and things appear whiter near the horizon.

If the atmosphere was 10x thick, there would be white light everywhere.
If it is 1/10 then there would be black everywhere and a blue sunset.

Note: Clapp thinks damnyouautocorrect.com, the museum of bad art, and overheardintheoffice.com is funny.

Also he believes that Alex Ross sucks.

Shoot reference with a small aperature and long exposure. When working on a film, try to use the same lens.

For a view that simulates the eye, use 52mm lens. 35 digital.

For digital camera, it's all about the lens and not the megapixels.

Tonal drawing is about:
  • edge
  • shape
  • value
Critique:

Squint with your glasses, not without.
Observe what you don't know.
Leaving out details is acceptable. Adding isn't.
Compare things across the board.
Don't overemphasize contrast.
Utilize soft and hard edges.
