Though it wasn't created in-camera, this double-exposure photograph is, nevertheless, breathtaking. Montreal, Quebec-based photographer Michelle Karpman superimposed the two shots – one taken from winter and one from the summer – using Photoshop. She then called it Sunshine On My Mind. On a rainy or snowy day like this, it's just perfect.
You can purchase a 12×12 print of it on Etsy.
