Custom framing to fit the subject Using an 80–200 mm lens I was able to pick up the great blue heron in my viewfinder as he approached my boat, fine tune the framing and fire off three or four shots as he flew by. The lens really allowed me to instantaneously crop the shot allowing space in front of the bird for him to fly into while avoiding cropping off the long legs trailing behind.


Making small things look big


Wide angle zooms (18–28 mm) tend to exaggerate the size of near objects and push distant objects further away. Here, a 20 mm zoom emphasizes the amount of water in the nearby over- flow and makes this Rideau Canal lock appear much higher by pushing the kayaks further away.


Making big things look small Longer telephotos, in the 200–300 mm range, have an apparent compression effect on objects in the scene. The use of a 300 mm zoom lens appears to compress all the locks, making them look 50 feet long instead of their actu- al 100 feet. This allowed me to fit five locks into the scene and accentuate their staircase effect.
