This weeks exercise is a lot of fun and even children can do it. Go with you camera intoyour front yard or any other place in your neighborhood that has a display of Christmas light. Use a tripod and a camera with a zoom lens. I picked my 24-105 lens. Mount the camera on a tripod and pick a long exposure time (30 seconds) and the appropriate f stop which may vary. During the 30 seconds exposure time change the focal length on your lens. You can do that slowly and consistently or in steps. Watch your results and learn from them. For addition help go to http://digital-photography-school.com/using-the-zoom-effect. As always, enjoy this exercise!
I photographed this image in my neighbor’s front yard. Notice that it is not totally dark. I found that the best time to photograph is after sunset and before “total” darkness.
