The Graslon Spark is an accessory for your DSLR camera that helps make 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.
