Project: Focal Lengths

Exercise: The Angle of View

Find a view that is open, but has some detail in the distance in the middle of the view.  Without moving, take a series of shots using steadily longer focal lengths, from wide-angle to telephoto, to demonstrate the narrowing of the angle of view as the focal length gets longer.

Exercise Learning

The nice part about the view I chose was that the aisle’s of trees grew shorter, and finally disappeared in the final shot, proving the narrowing of field and enlargement of the subject as per the lessons intention when moving from wide-angle to telephoto lenses.  By zooming in on the wide-angle image it mimicked the same principle as printing and using a magnifying lens, only easier.
