These beautiful photos of the sky were created by stacking images of the same scene together by PhotographerMatt Molloy.
(controls differ depending on the subject and lighting conditions).
I then merge several photos into one image using Photoshop.
(The movement of the stars is actually from the earths rotation).
I think its an interesting way to observe time.
you might see a time frame of several hours in one image, something our eyes cant do naturally.
