Another shot from the Okavango Delta near Kwetsani camp, and another unscheduled blog entry to try and clear the backlog. In common with several shots I’ve presented over the last week or two, this shot was taken from a small boat and features the abundant lilypads.
Canon 5D with 24-105mm zoom lens at 24mm and F13, shutter speed 1/40 second at ISO 400.
Wide Angle Lenses.
When people think of wide angle lenses they often think of broad landscapes, the wide angle will allow me to “get the whole scene” in the frame. This is of course true, but the wide angle lens has another characteristic which makes it particularly useful and that’s its extended depth of field. In order to give the landscape a feeling of depth, it’s really worthwhile looking for interesting foreground material and getting close to it. The perspective effect of the wide lens, combined with a close foreground will add emphasis to that foreground material. In this instance I positioned the camera low to the edge of the boat to make the most of the lilypads, the closest of which was probably only a metre away. To further take advantage of the foreground, I chose a small aperture to ensure the greatest possible depth of field. Everything in the frame is sharp.
Also interesting here is the way the light plays on the water. Being sunset the tones in the sky and on the horizon are warm with red and yellow elements which are of course reflected in the distant water. The further towards the bottom of frame we get the colder the tones become. At this point we’re looking down at a steeper angle avoiding the sunset’s reflection. The broad perspective of the wide angle lens allows us to capture the contrasting tones which become a feature of the image.
The take home point out of all this? Look for and take advantage of good foreground material particularly when using wide angle lenses. To further illustrate the point, put your hand over the bottom half of the picture and visualize the remainder as a panoramic, not very interesting is it?
