  The authors examined the suitability of using a Digital Single Lens Reflex
(DSLR) camera for stellar photometry and, in particular, investigated wide
field exposures made with minimal equipment for analysis of bright variable
stars. A magnitude-limited sample of stars was evaluated exhibiting a wide
range of (B-V) colors taken from four fields between Cygnus and Draco.
Experiments comparing green channel DSLR photometry with VT photometry of the
Tycho 2 catalogue showed very good agreement. Encouraged by the results of
these comparisons, a method for performing color-based transformations to the
more widely used Johnson V filter band was developed and tested. This method is
similar to that recommended for Tycho 2 VT data. The experimental evaluation of
the proposed method led to recommendations concerning the feasibility of high
precision DSLR photometry for certain types of variable star projects. Most
importantly, we have demonstrated that DSLR cameras can be used as accurate,
wide field photometers with only a minimal investment of funds and time.
