A new digital camera comes with a multitude of features, but one of the first things we consider is the ability and power of the lens. But how many of us for real understand what can be acheived by creative use of lenses?
[b]Lens[/b]The inequity in the middle of a wide angle lens and a telephoto lens is about more than just magnification. To get the most out of your lenses, you also need to understand how they influence depth of field and perspective.
You already know that the telephoto lens enlarges all things in the picture. But did you also know that when you zoom in, or attach your large telephoto lens, you also sacrifice the depth of field around the subject? This is a great formula for eliminating a distracting background from your photo. The supervene is twofold: the narrow field of view minimizes how much of the background we can see, and the small depth of field ensures it will be thoroughly out of focus.
So when photographing subjects like habitancy and animals, using your telephoto lens (or zooming in with your zoom lens) is often the best approach. The supervene will be a very three dimensional effect, with the field appearing to emerge sharp and clear from the blurry background.
On the other hand, your wide-angle lens does just the opposite. It for real does a lot more than just make all things appear smaller. The wide angle lens takes in (as the name suggests) a much wider angle of view, and it has a much stronger depth of field than a acceptable or telephoto lens. That means that not only will you see a lot more of the background in your photo, but it will also be much more focused.
Consequently the wide-angle lens is not so good for portrait style photos, because the background is too distracting. On the other hand, it is perfect for landscape pictures, especially when you have objects both in the foreground and background that you need to keep in focus.
The other aspect of your selection of lens is perspective, which is a lot harder to account for without pictures, but I will give it a go.
Have you ever watched a cricket match on television? (If you are from the United States substitute baseball here). When you see a close-up image of the batsman, you may consideration that the wicket keeper (shortstop) seems to be standing right behind him, and the crowd is only a short length additional back. When you see a side-on view, you may be surprised to see that the wicket-keeper is standing about ten meters behind the batsman, and of procedure we know that the grandstand is a good 60 meters or so additional back. So what's going on?
The acknowledge is simple. The very large telephoto lens used for the close-up shot tends to make objects at different distances seem much closer to each other than they for real are. In short, it compresses the natural perspective, development habitancy separated by some length appear to be quite close to each other.
This principle also applies to landscape photography. Dream a scene with a tree in the foreground and a mountain range in the distance. By standing a long way from the tree and shooting it with a telephoto lens, you will also improve the mountains in the background. As a result, they will appear much closer to the tree than they for real are.
Now Dream taking the same scene with a wide-angle lens. By standing a lot closer to the tree, you can photo it in such a way that it takes up the same amount of space in the composition. However, by reducing the scene to fit the tree in the frame, you also sacrifice the background...making it appear much additional away than it for real is.
In this way, the wide-angle lens does the opposite of the telephoto lens. It exaggerates the perspective, development objects at different distances appear much additional apart than they for real are.
Put simply, the end supervene of these two approaches is this; the telephoto lens adds prominence to the background, which will appear relatively large in your photos (albeit with depth of field issues in some cases). The wide-angle lens adds prominence to the foreground, development the background appear much smaller and more distant.
Thus by simply changing your selection of lenses, you can dramatically alter the impact of your photos. Dream the creative possibilities; you have the power to operate how the viewer sees not only your subject, but how it relates to the surroundings at the same time.
This is a tough field to account for without pictures, but hey - you have a digital camera. Why not step covering right now and try out a few of these ideas. Or if you are feeling lazy, sit down and watch some sport on telly. It may for real teach you something about photography.
