Photography through Astronomy
As I was browsing the internet the other day, I stumbled across an article that may interest those of you who enjoy photography. It details a trick where you can use the rotation of the earth to create neat, long exposure photos. First, you need to know how to go about finding the North Star (Polaris), which is made easy by this picture:
Now with the north star located, you can create background designs with the stars. Over time, all the stars rotate about the North Star so the direction of your camera in terms of the North Star will change the pattern of the star movement in your photo. For example, angling your camera directly at the North Star will produce a circular effect whereas directing your camera to the left will produce arcs going from top to bottom in your photo. Chicago, obviously, wouldn’t be the best place to experiment with this, but the suburbs, and certainly while camping, would be great opportunities to experiment with this. Then once you get some photos you like, fine tune them or toy with them in Photoshop until they are to your liking. Get more details or see examples here.
