Plasticity

The degree to which three dimensionality of the actor is brought out. A solid, three dimensional form sparkling in space. The opposite of flat, dull, two-dimensional.

Visibility

1) How much do we see: the degree of visibility.

2) Equally important is how we see.  Do we see detail well, or do we see form well? A back light and a front light each give good visibility, but of different things.

1) Comment on the plasticity and visibility effects of each individual light –
front, angled front, side, down, back

2) A:  Comment on the plasticity and visibility effects of the following combinations.

  • Two angled front lights
  • Two side lights
  • Two angled front lights with front light
  • Two side lights with front light
  • Two angled side lights with two angled front lights

B:  Now look at the above combinations with a back light or down light added in.

 

C:  What are the advantages and disadvantages of each combination of lighting positions.

– Flexibility, contrast, eveness, detail, form.

3) Use the units to create the feeling of the following looks. Do not use color, use direction and intensity to create the feeling.

All too often we use color as a symbol or sign for lighting effects and forget the very important qualities of Intensity and Direction.
