Wide-angle lenses - characteristic and instruction

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:

1. When landscapes want to expand a large space, for example, taking pictures of the city.
2. When it is desirable for a photographer to remain unnoticed, taking pictures on the street.

Wide-angle Canon lenses have a diagonal field of view of 100 degrees, and width - 88 (the usual 35-millimeter frame).

How do wide-angle lenses work? Their features

- They have a lot of space. Therefore, the objects shown in the photo are reduced by half. In this, shooting differs from the usual standard lens. To put it more simply, a wide-angle lens should not be used to shoot mountain landscapes, because it crushes severely.

You can solve this problem. You should add to the frame some large objects that act in the foreground. It can be:

• Bushes;
• Puddles on the roads.

Thus, the effect of the active spot will be created, for which the viewer can catch the eye.

- When using wide-angle lenses, optical images may appear in pictures. These are barrel-shaped curvatures (distortions). They appear on the periphery of the frame. But do not argue that the quality of photos is deteriorating because of this effect. Sometimes it is the other way around. The composition in the picture looks more comfortable with the help of barrel distortions. If you do not want to distort the space, then take a closer look so that there are no trees or corners of the houses along the edges. They strongly bend. The camera needs to be kept precisely horizontally, because there will be blockages of verticals.

- Wide-angle lenses have an increased "glare". Therefore, you need to monitor the location of the sun when shooting on a sunny day. If possible, use the hood. If your outfit does not have it yet, then a little difficulty awaits you. Due to the large size of the wide-angle (77 mm or more), it is difficult to select the lens hood and filter. If you find them, then they will cost you a decent amount.

- Wide-angle lenses for Canon, combined with a short-focus lens, have the specific use of a polarizing filter. Since the sky has uneven polarization 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 choose a polarizing filter with a narrow bandage ring. They are made specifically for wide-angle lenses and do not allow blackouts to get into the corner of the frame.

- With such photographic lenses, the use of the built-in flash light simultaneously with the short-focus option is ineffective. A weak flash can not illuminate a huge spectrum of space and will be located close to a lens with a large diameter. Therefore, the images will have a dark spot in the form of a semicircle. It will result from the fact that the lens will cast a shadow from the flash. It falls into the frame from the bottom.

Of course, not only wide-angle lenses cast a shadow, but other types. However, because of the smaller angle of the field of view, it does not fall into the frame.

The way out of this problem is to increase the focal length or apply a remote flash.
