"I am trying to understand the umber underlayers. Using
a computer analogy, if I were to start with a color photograph
in one of the top-of-the-line graphics programs, Corel
PhotoPaint10, and convert it to Grey Scale, would the
resulting image be approximately what I should be trying
to achieve with the umber underlayers?"
This tonality will be to contrast. make it brown instead
of back, and imprimatura hue instead of white.
"In the "Portrait of Anna" video, a scale is used in
which the tones of grey are arranged in order and numbered.
Where can I get one of these scales?"
