On my easel right now is a prepared board on which I am doing
a "cover" of one of Alfred Sisley's paintings.
This one has water, sky and distant trees -
good for me to try to render in a similar way.
Of course the photo I am using is in a book and
very small, so really hard to copy exactly ...
I don't want to copy it exactly anyway.
I am taking my time, but not trying to mimic -
just getting a similar feeling, I hope.
These two shots were of my trying to get the values started,
and I did add a little color.
