In the case
where the picture has been flat it has arisen from the sitter being
placed too far back from the window, so that the direct light falling
upon him has been too feeble to produce any strong lights, and the
reflector arranged so that it received a stronger illumination than
the model, then reflecting it on to the latter, quite overpowering the
dominant lights. The remedy for this is simply to bring the sitter more
forward, so as to obtain a stronger dominant light.
With regard to the time of exposure: we must again impress upon the
student the necessity for placing the sitter as close to the window
as can be conveniently done, for then he will receive the strongest
illumination; and, no matter how strong the shadows which may be
produced, they can always be modified sufficiently by the judicious use
of the reflector. Of course, in practice there is a limit as to the
closeness the sitter can be placed, inasmuch as if too near there will
not be room enough for the background. As we have before said, the
effective light falling upon the sitter is governed by the amount of
direct skylight to which he is exposed. For experiment, let any one seat
himself, say, one foot from the window and sideways to it, and note the
amount of sky that can be seen from this position, then take a seat six
feet within the room, and note it from thence.
