Challenge has finished
Most of the photos people take use the camera to capture what people see; the challenge is to capture things that a person normally would NOT be able to see. The subject might be unseen because it is imaged in NIR (near infrared), happens too quickly (use a fast shutter or flash) or too slowly (use a long exposure or time lapse stacking) for human perception, is seen from a place your camera can go but you can't, etc.

This image is literally the difference of two very ordinary images taken from the same position by a camera I use as a security monitor controlled by a PC using Linux and gphoto2. The first image was taken in July 2008 with most everything green; the second was captured in February 2009 with snow on the ground and trees bare.
