To make exposures, the slide is withdrawn, the "safety cover" pulled out and the film pack operated for successive exposures just as in film cameras.
Then at any time the slide may be reinserted, the adapter removed and the subject sharply focused on the ground glass by precisely the same method you would follow in using glass plates.
The Adapter is loaded just like a Plate Holder.
Thus a Premo plate camera will take films or plates with equal facility; it offers the daylight loading and other features of the Premo Film Pack, as well as every advantage of the ordinary focusing camera; and many of these Premos are as compact as purely film cameras.
With the Premo Film Pack Adapter, also, it is an easy matter to make multiple pictures (two or more exposures) on one film.
This is done by manipulating the slide in connection with the film pack tab, and the procedure is fully explained in the Premo manuals.
