Light 2: modelling 3D in 2D

from Simon Towler’s ‘theory of light’ series. Foundation material on thinking of light separate from colour, and using it to model three dimensional forms:

“As photographers and artists we are image makers. We can make flat, two dimensional images that represent three dimensional scenes in the real world.”

Light 1: What’s light for?

The introduction to Simon Towler’s ‘theory of light’ series.

“The medieval master mason was able to draught the plans for his cathedrals, and scribe the templates of their carved stones, using just simple compass and square, applying his fundamental knowledge of measure and proportion, step and repeat.”

So let’s start learning what light is for in images, what it does and what we can do with it.
