The Spark is an accessory for your dSLR camera that makes pictures taken with
the built-in pop-up flash more pleasing. By making a larger light source and
taking advantage of whatever bounce is available, the Spark reduces overblown
highlights and softens shadows.
The Spark pop-up flash diffuser will work with most dSLR cameras, simply
slide it into the hot shoe mount and take pictures as normal. The Spark will not
inhibit the normal triggering of the flash and does not generally require that
you change any settings.
