Welcome to the fourth in a 12 part series about how to improve your nature photography.
Step #4 – Lens do more then get you closer.
From super wide angles to extreme telephotos, lens are a big part of photography. Every photographer experiences lens lust at some time; the idea that our photographs would be better if we only had a new lens. Yet many photographers fail to use their lenses effectively. Take your average photographic situation and think about which lens you would like to use. Your answer probably depends on how close you are and how big you want the subject to be. If you wish you were closer, you pull out the telephoto lens. If you want to keep the subject small, you reach for the wide angle.
It is true that lenses will help get you closer, or move you back, but your feet can do that for free. Understanding the impact different lenses have on the final image is an important step for the developing photographer. 50mm lenses are commonly referred to as “normal.” The question is what does normal mean? Photographically speaking, a normal lens is one that records the scene in a way that is similar to how the human eye sees it. A similarity in angle of view and perspective is shared. As we shift away from normal, our lenses began to deviate from reality in a number of ways.
Telephoto lenses start at around 100mm and extend all the way out to 800mm. Sure these lenses enlarge the subject, but they also manipulate the scene in two unique ways.
First, telephoto lenses have a drastically reduced angle of view. Where a 50mm lens records 39 degrees, a 500mm lens records a mere 4 degrees. The impact for photographers is twofold. As we well know, the reduced angle of view gives the appearance that the subject is closer. This limited angle of view has the added advantage of limiting how much of the background is included. This gives the photographer much greater control over what is included in the background because moving a few inches can totally change an image’s background.
Second, telephoto lenses compress distance. Subjects that are far away from each other appear closer together when viewed through a telephoto lens. For example, the image above gives the appearance that the rock hoodoos of Bryce Canyon are stacked very close together. This is an optical illusion as there is often between 30 – 50 feet separating the different hoodoos. This compression effect gives photographers the ability to show or imply relationships between subjects that might not otherwise be obvious.
Telephoto lenses, with their narrow angle of view, are outstanding tools for visually isolating subjects and removing distractions.
Where telephoto lenses compress, wide angle lenses expand. Starting at around 35mm, wide angle lenses are the go to tool for landscape photographers who wish to document the grand landscape. As the name implies, wide angle lenses encompass an expanded angle of view when compared to longer lenses. Angle of view can range from 54 degrees (35mm) to 108 degrees (13mm). Yet including more means additional care must be taken when composing the scene if distractions are to be prevented.
At the same time, wide angles distort distance. While telephoto lenses compress, wide angles exaggerate, giving the appearance of greater distances between subjects. Again lets look at an example from Bryce Canyon. The above image shows a trail wandering down into the hoodoos. Looking at the hoodoos, it is clear that there is a fair amount of space between they. Yet this is the same basic area that was photographed in the previous image. By using a wide angle lens, a radically different perspective about how the hoodoos are spaced was created.
Wide angle lenses do not isolate elements the way telephoto lenses do. Wide angles are more inclusive and should be used so as to take advantage of that inclusivity. By placing key elements extremely close to the lens (a few inches), size and distance can be manipulated so as to emphasize particular parts of the scene.
