THE ARTIST'S STUDIO.--INSTRUMENTS AND HELPS FOR THE APPLICATION OF
PERSPECTIVE.--ON JUDGING OF A PICTURE.
On the size of the studio.
509.
Small rooms or dwellings discipline the mind, large ones weaken it.
On the construction of windows (510-512).
510.
The larger the wall the less the light will be.
511.
The different kinds of light afforded in cellars by various forms of
windows. The least useful and the coldest is the window at _a_. The
most useful, the lightest and warmest and most open to the sky is
the window at _b_. The window at _c_ is of medium utility.
[Footnote: From a reference to the notes on the right light for
painting it becomes evident that the observations made on
cellar-windows have a direct bearing on the construction of the
studio-window. In the diagram _b_ as well as in that under No. 510
the window-opening is reduced to a minimum, but only, it would seem,
in order to emphasize the advantage of walls constructed on the plan
there shown.]
