Life through a different lens

(Continued)

Care must be taken by the photographer to not include their feet, tripod legs or the brim of a baseball cap. Sun flare can also be a problem, unless the photographer wishes to include it. In a forest scene, I generally block the sun by using an overhanging tree branch, which also helps to frame the scene.

At times, I purposely include my shadow. In one instance, I located it between two parallel tree shadows, leading the viewers’ eyes into the photo.

FISH-EYE LENSES

  • A fish-eye lens is basically an ultra-wide-angle lens that covers from 100 to 180 degrees and bends light rays to produce intense visual distortions.

     
  • Objects closer to the lens appear larger than life, while those near the edge or circumference, seem more distant and are curved.

     
  • The term "fish-eye," dating back to 1906 and attributed to American physicist and inventor Robert W. Wood, is based on the panorama that a fish supposedly views.

     
  • A common, non-photographic use for fish-eye lenses is found in doors of motel rooms and apartments, as it allows the viewer to see down the hallway as well as visitors who might be shorter.

     
  • The sale of fish-eye and other extreme wide-angle lenses has increased in recent years as the current generation of photographers looks for ways to extend the vision of digital cameras.
