This article will discuss how to properly use wide-angle lenses. Some features of their work are also considered. Very often, wide-angle lenses are used for the following purposes:
- When you want to expand landscapes with a large space, for example, shooting a city view.
- When it is desirable for a photographer to remain unnoticed when shooting on the street.
Canon's wide-angle lenses have a diagonal field of view of 100 degrees and a width of 88 (of a typical 35mm frame).
How do wide angle lenses work? Their Features
- They have a large space capacity. Therefore, the objects depicted in the photograph are reduced by half. This is the difference between shooting from a regular standard lens. To put it simply, wide angle should not be used for shooting mountain landscapes, because it is very small.
You can solve this problem. You should add some large objects to the frame that protrude in the foreground. These could be:
- puddles on the roads.
Sothe effect of an active spot will be created, for which the viewer can catch the eye.
- When using wide-angle lenses, optical distortion may appear in pictures. These are barrel-shaped curvatures (distortions). They appear on the periphery of the frame. But you should not argue that the quality of the photo is degraded due to this effect. Sometimes the opposite happens. The composition in the picture looks more comfortable with the help of barrel-shaped distortions. If you don't want to warp the space, then take a closer look so that there are no trees or house corners on the edges. They are strongly bent. The camera must be held exactly horizontally, because there will be blockages of verticals.
- Wide-angle lenses have increased "glare". Therefore, you need to monitor the location of the sun when shooting on a sunny day. Use a hood if possible. If your equipment does not yet have it, then a small difficulty awaits you. Due to the large size of wide-angle lenses (77 mm or more), it is difficult to match the lens hood and filter. If you find them, they will cost you a decent amount.
- Wide-angle lenses for Canon, combined with a short throw lens, have the specifics of using a polarizing filter. Since the sky is non-uniformly polarized at a wide angle, a dark blue spot will appear on it. If you want to shoot a horizontal landscape with the sky, then the wide angle is not recommended for use with a polarizer. If you still want to try, then you should opt forpolarizing filters with a narrow bandage ring. They are made specifically for wide-angle lenses and do not allow blackout to enter the corner of the frame.
- With such photo lenses, using the built-in flash at the same time as the short throw option is ineffective. A weak flash will not be able to illuminate a huge spectrum of space and will be located close to a lens with a large diameter. Therefore, there will be a dark spot in the shape of a semicircle in the pictures. It will turn out due to the fact that the lens will cast a shadow from the flash. She enters the frame from below.
Of course, not only wide-angle lenses cast shadows, but other types as well. True, due to the smaller angle of view, it does not fall into the frame.
The way out of this problem is to increase the focal length or use an off-camera flash.
