I must admit, I've never tried creating diptychs before. I've certainly thought about it...I even made a PhotoTao Card prompt for it to encourage myself. Perhaps this year I will explore this wonderful idea of juxtaposition of images.
Of course, this idea has been used for a long time in the art world. Triptychs, a pairing of three images, are another common form. We tend to think of the photograph as a solitary image but this coupling dynamic is worth examining.
