Heart-shaped Lights for Valentine’s Day Let’s get romantic with some heart-shaped lights this Valentine’s Day Directions are below. A heart stamp from the craft store makes a nice heart. Grab a piece of black construction paper. Cut it into this basic shape. The circular shape should cover your lens opening. Notice that the heart shape has been taped to the center. That’s because my stamp doesn’t stamp very far from the edge of the paper. I had to cut the center out of the main shape and tape a smaller piece of paper with the heart shape to the main piece. (This is good because you can remove the heart later and add shamrocks for St. Patty’s Day) Attach the black paper object to the front of your lens. I use a hair tie. You’re almost ready to go. I’ve found that a lens in the 100mm range makes the best heart shapes. Switch to Manual focus. Blur the scene in front of you. The view through the viewfinder is dark. It might help to switch the camera to spot or partial metering. Bright lights work best. This is a photograph is a busy street.
