Diptychs

Traditionally, a Diptych refers to something that presented in twos that are connected using a hinge of some sort.

The idea and use of diptychs have been around since the middle ages, where they were used to celebrate weddings, becoming a well respected roman, or for private use. Often, they came in the form of panel paintings, but ivory was also used more religious scenes.

However, Diptychs also mean things that are presented in pairs, including photographs.

They can be used to tell two parts of a story, or to simply show two images that relate to each other. It's often thought, however, that for a successful diptych the two images must be able to work as a single image alone and not rely on the other. 

"The word diptych comes from the Greek root "dis", meaning "two," and "ptykhe," meaning "fold.""

In this example by Jay Watson (Faces) the two presented images are not of the same subject, however they represent the same thing and are visually similar. They're used to send a message to the viewer. I personally read the message as showing the similarities between a man and his pet.

This image by Julian Rosefeldt (Piero Steinle, Detonation Germany (No. 1, Diptychs), 1999 ), however, uses the same subject in both images. He uses them to show movement and enhance the feeling of destruction, allowing the viewer to see not just one frame of the houses being ruined, but two.

I am interested in using diptychs in my final edit to show more of the life and change throughout the life of the tree, and I think it will bring more energy to the images if they're supporting each other.
