In photography, a diptych is a pair of photographs placed side by side to form one single artistic statement or comparison. The images can be identical or similar in composition, they can show different angles of the same scene, or they can demonstrate polar opposites such as morning and night, old and new, or before and after.
Diptychs are great because they can deliver twice the storytelling impact of a single image. We want you to try this technique for this week's round of our Mashable Photo Challenge.

You can use Photoshop on your computer or any collage app on your smartphone to combine your images. Feel free to check out this Flickr group for some diptych inspiration.
Follow the directions below to submit your photos by Tuesday, Dec. 3, at 12 p.m. ET. We'll feature some of our favorite ones on Mashable, as well as on our Facebook album, Pinterest board and Google+ page.
