The 50.6 megapixels full frame sensor in the Canon 5DSR camera is of great help when comes the time for bird photography. It allows major cropping of an image without any loss in quality.
With a little patience, it was possible to take a picture of a hummingbird in a public park in Victoria, British Columbia after the bird finally rested on a branch for a few seconds. Without cropping and a powerful 500mm telephoto lens, it would have been difficult to produce a sufficiently large and clear image of a five centimeter bird.
I used a Canon 5DSR equipped with a Canon EF 70-200 f2.8L II USM telephoto lens. The camera was adjusted on APERTURE mode. The telephoto lens stabilizer was activated. The autofocus was set on the SERVO mode to insure the image sharpness in the event that the subject started to move.
But the hummingbird was so small that the autofocus constantly whizzed between the bird and the leaves. I had to switch to manual focus and use Liveview.
Once the picture was taken and cropping was done, few contrast and luminosity corrections were necessary in order to enhance the bird’s plumage which happened to be backlighted. RAW files facilitated the edition in Photoshop.
Likewise, the background intensity of the colours was corrected to avoid distracting from the principal subject. The initial picture, in landscape format, was later changed in the portrait format, which allowed the exclusion of several branches around the bird which were imposing and diverting attention.
Naturally, the chosen depth-of-field blurred the background, helping the hummingbird to stand-out.
