Here we see an illustration of some of my
ideas about underpainting.
First, notice that the paint is kept quite
thin. Not so thin as to be 'washed out' -
but no paint build up. You can clearly see
the weave of the canvas throughout.
(More on this later).
Second, all values in the underpainting will
be darker than the intended final painting.
In general, I will want to be painting light
over dark throughout the latter stages of
the process. (Again, more on this later).
Finally, the colours in this underpainting will
be warmer than the finished painting. This
isn't always the case by any means - but
you will have noticed the predominance of
cool green in the photos. I intend to have
these in the final work, so we will need
some warm colours underneath to balance
