Yes, we are close to Saint Valentine's day, and ... yes, me too, I love hearts. And I sometimes have hearts in my photos, either shot or painted.
Here are some
Here I duplicated layers, applied filter>blur>gaussian blur, then in blend modes, multiply or overlay.
And I am very fond of this one, in which I left the aperture to very low shutter speed while I "painted" the shape of the heart with a small torch, in a completely dark room.
And my daughter drew these hearts. Then I photoshopped them, adding color and a shadow:
Enjoy your Valentine!
