10 Operation with freemask
The transmitter „ freemask “ has all the functions of the Strobe
Wizard Plus and is operated the same way.
Additionally, the transmitter is used for the freemask method.
„freemask“ is a photographic method to produce digital clip-
ping masks. For this method, the camera takes two exposures
in sequence. Exposure values and camera position remain
unchanged for both exposures. The freemask transmitter con-
trols the two flash groups used for both exposures:
• The flash group for the actual motif to be photographed
• Flash group for the backlighting-like background lighting
(mask lighting)
A mask layer is easily created with the help of image editing
and thus the motif can be extracted.
The Porty L has three other „F“ channels besides the standard
„C“ channels for this.
• The flash units for lighting the motif are assigned to the „C“
channels.
• The flash units for the lighting background to be masked
are assigned to the „F“ channels.
When selecting channels, (see „Setting receiver“ on page 35)
), the freemask receiver channels „F1“, „F2“ and „F3“ come
after the Strobe Wizard channels „C1“, „C2“ and „C3“.
Make sure that the channels are assigned accordingly, e.g. C1/
F1, C2/F2 or C3/F3.
