The Use of a Single Lens in Portraiture

quality of the resulting picture. If a portrait com-
bination on a rectilinear lens is the only one at
his disposal, a good result can often be obtained
by removing the back lens of either form and
working with the front only. This will increase
the back focus to about double, and the exposure

obtained by using the largest diaphragm with
which it is possible to give the definition required.
The great merit of a single lens in portrait work
is its depth of focus; with the open aperture, or
largest stop, it will be noticed that there is really no
point in absolute focus, but, on the other hand,
pictures will be surprised to find that a single needed to about the same extent. It must, how-
