Windows have been ruining photos ever since the first time a photographer tried shooting through one.
Unless you bring along dedicated contraptions or start messing around with cloths and funny angles, shooting through the glass will likely lead to an annoying reflection that will make you want to smash it to pieces. (If you’re actually trying to get a reflection then scratch everything I said; windows are awesome).
This problem might soon come to an end, though; as researchers say they’ve developed an algorithm that can automatically remove reflections from digital photos. The algorithm can’t remove all types of reflections, but it does an impressive job with the ones it can remove.
