Unit 4 Activity 4


Photo by Jack Fusco

Using a slow shutter speed allows for a lot of motion to be recorded in a picture. In this picture, you can see the complete travel of stars overnight. Taking a picture like this can be very tough, you must keep a camera nearly perfectly still for an entire night. To make sure that the image isn't over-exposed, you have to use an extremely small aperture size. With this aperture, you also get a very large depth of field, capturing detail of the entire picture.
