Take a bare glass filter, hold it so that light reflection off
the surface can be seen.  Then take a long, very thin
object like a pin or the tip of a pen and hold it over the
filter so that its reflection can be seen. There will 
actually be two reflections of the pin on the surface, one
a little more pronounced than the other.  The more 
pronounced reflection is from the front surface and the
lighter one is from light reflecting off the rear surface.
Now try it with a HOYA Digital Multi-Coated filter and
see how much more dim the reflection is, a dimmer
reflection means less light is reflected off the surface 
of the glass.
Digital camera CCD or CMOS sensors are highly 
susceptible to reflections - this stray light can ruin your
photographs!  Don't risk your valuable photos by using
bare-glass filters.
