Many amateurs have of late discarded their larger equipments, and
for general work use the smallest sizes, such as the Detective
Camera and the Bijou or Novelette, which are of the smallest sizes,
such as 3-1/4×4-1/4 and 4×5.
It is contended on their part that these small outfits, which are so
light and portable as to give the minimum [p189] of trouble in
their use, give also (when good lenses are used) the most brilliant
and perfect negatives, which are capable of being enlarged to any
desirable size. Indeed, the copying and duplicating apparatus may be
found in the rooms of many of the leading amateurs. And by its use
many valuable negatives are duplicated, and secured against loss by
breakage; others are enlarged to more useful sizes, and most
beautiful transparencies are made.
