The Holga 135BC camera is desired by art
photographers the world over. Reminiscent of the Diana camera of the
1960s and 70s, characteristic vignetting focuses the viewer's eye and
adds to visual impact. This version of the Holga differs from the
standard version in that it features an internal mask which "cuts" the
corners creating a soft vignetting effect. Hence, the name "Black
Corner" version.
A Holga has four focus marks on the lens
barrel. Simply rotate the barrel to the setting that most closely
corresponds to your situation. Feel free to use your own setting that
might fall between these icons.
