Got $10? Get some reading glasses, or grab some old eyeglasses, pop out the lenses, and hold them in front of your lens to create magical effects. You’ve probably seen this look before; perhaps you didn’t know how it was done.
It’s not very complicated. You just hold the eyeglass lens in front of the camera, sometimes moving it, letting it catch reflections and distort and blur the foreground. It can create “lens-wacking” effects, light-leak effects, and a tilt-shift appearance. Be sure to shoot wide open on a fast lens. Defocus is critical to making this effect compelling. Try using two lenses at once for an even more pronounced effect.
From now on, I’m keeping two lenses in my change pocket of my jeans whenever I shoot.
Thanks to Stephan Kot for the tip.
