not be moved. The Lens.—Any lens may be used, but I have found, a soft-focus lens, such as the Smith Semi-Achromatic, most satis-factory, as the diffusion given by this lens, greatly adds to thedecorative effect, especially when taking nude figures. An-other advantage of using such a lens is that no retouching isnecessary. Lens Hood.—The main source of light coming as it doesfrom above and behind the subject, it is necessary to put apaper hood on the lens to keep the direct rays of light fromhitting it and causing halation. This hood can easily be madeby wrapping a piece of black or dark paper, or card-board,around the lens and tying it with twine.

I generallygive from Ten to Twenty-Five or Thirty Seconds accordingto the light. Of course the subject, pose, background, andeffect desired will have a great deal to do with the exposure.A few trials will give
