Trilogies came about as I was experimenting with multi-exposure images to make panoramics. As I worked putting the multi-exposures together into one image, it became apparent that, after joining the images, it would be visually appealing to then separate them into three pieces.
Trilogies are long and narrow and, usually, horizontal. They fit great over beds,sofas and any other space where you want a lot of length without too much height. Be sure to view them in their largest size to get the fullest effect.
