ValueComp is a tool designed for comparing
value scales through a value scale filter window. In
addition the window allows you to set up a composition
with ease. Double sided printing. An absolutely necessary
aide for plein air artists.
to find the value
the ValueComp about one foot from your eyes, see the
object through the value filter window with one eye.
You can compare the object with each gray scale value
to decide its value.
the beginning, try to limit your value range to only
four or five within scale 3 to 7. Later on you can fine
tune by adding more value; finally add the lightest
value 1 & 2 as highlights, and 8 & 9 as accents
if necessary. This is helpful in plein air painting
in general, but not the only way for value.
to use the composition filter window
the ValueComp about one foot from your eyes, and see
through the composition window with one eye. The triangles
along four sides of the window denote the 1/3 positions
on each side. When your eyes connect them will form
the place your focal point by placing your object at
either one of the intersections. Move around till you
find the ideal composition.
