A triptych is a work of art which is divided into three sections. I took a photo of Spaceship Earth looking right up one of the pylons. I decided to use FX Photo Studio to make a few special effect versions of the Spaceship Earth photo and create a triptych from them.
A triptych of Spaceship Earth.
In this case I used the same photo of Spaceship Earth. I could have used three different photos of the same subject or of different subjects if they worked together. For me, it means the three subjects should relate together in some way.
