THE [NOVEL CAMERA] WITH DOUBLE SWING BACK IN THE ACT OF BEING REVERSED.
An ingenious improvement has been introduced in connection with the Fairy and [Novelette Cameras], which is shown in the cut.
It consists in the use, with a 5×8 Camera, an additional body and bellows for 8×10, which can be attached to the front and bed of the 5×8 on removal of the 5×8 bellows to back. This substitution can be made in a few seconds, giving the user the command of two Cameras at small expense.
THE VIEW LENS.
(See article on lenses in Part First.)
View lenses may be classed in two groups:
Single combination lenses and double combination lenses.
Single combination lenses are intended for producing pictures of inanimate objects, in the production of which the time of exposure is of minor importance. They are of greater focal length than the double, and, on account of their simple form, are less expensive.
The combination consists of a meniscus, composed of two lenses, one convergent, the other divergent. The two are cemented together, so that only two surfaces are presented to reflect light. This lens is well calculated p158 for out-door work, but does not give such roundness of form nor such delicacy and finish as may be obtained by the double combination. But it has greater depth of focus, and, having but two reflexive surfaces, fits it peculiarly for views of foliage, and enables it to work into the green of the landscape more completely and vigorously.
