I did some experimentation with bokeh filters for portrait photography. If you put a shaped cutout on the front of a lens, then the out of focus bokeh from points of light behind the subject take on that shape. I think hearts suit this particular model (my wife).
This experiment worked out really well! I don't know that i would have thought of that and the heart distortions in the light were really cool. Love really is in the air!
Thanks @castleberry.
