What should I do if I encounter lens distortion when shooting?

Friends who know a little about photography believe that we are all familiar with the situation of "lens distortion". That is, when we take pictures, the horizontal straight line that was originally in a horizontal state will appear radian or scattering because of the characteristics of the lens, which looks a bit distorted. This is what we call "lens distortion", which is more common in wide-angle lenses and telephoto lenses. In this case, the deformation we see is more obvious. So this kind of shooting defect is caused. What shall we do? Actually, there is no need to be too alarmed. Everything has two sides, and "lens distortion" is no exception. So how can we make use of its advantages or correct problems? Next, let's take a look.

How can we judge whether the lens in a photo is deformed or not? The easiest way is to shoot a wall or ground with a balanced texture, and observe whether the horizontal and straight lines in the photo are distorted, so as to judge whether the lens will be deformed. Generally speaking, if there is lens distortion, it will be as shown in the following figure.

Everyone knows that the wide-angle lens is one of the lenses prone to "lens distortion". In many cases, wide-angle lens distortion does not always destroy the beauty of photos. As long as it is used properly, you will find that this is also a good shooting technique. Next, let's take a look at five situations that make good use of wide-angle lens distortion!

First, wide-angle lens deformation can make the building look more magnificent.

We can put the building on the edge of the photo and deform it through a wide-angle lens to make it look more magnificent, which is also one of our common situations.

Second, wide-angle lens deformation will increase the tension of landscape photos.

Wide-angle lens deformation can not only give the landscape a sense of perspective, but also make us feel the sense of space of the landscape, make the photos look as if they are there, and feel the tension of the photos.

Third, with the help of lens deformation, people can look more slender.

When shooting portrait works, using wide-angle lens to deform can increase the height of our body to a certain extent, but it should be noted that the hand or foot of the character needs to be placed on the edge of the photo to have the deformation effect, but excessive deformation should be avoided, which will look strange.

Fourth, the wonderful use of fisheye lens.

The most exaggerated distortion effect is the fisheye lens. The viewing angle of the fisheye lens is close to 180 degrees, and the whole edge of the photo under the language lens will be distorted. This can do a lot of interesting effects. Of course, the fisheye lens can also be used to take wide-angle photos, as long as the composition is as horizontal as possible.

Fifth, you can also use a wide-angle or fisheye lens to shoot a big head effect.

Through the lens deformation effect of wide-angle glasses or fisheye lens, you can shoot as close to the subject as possible, and you can take pictures as interesting as a big-headed dog!

How to fix the lens distortion?

In order to repair the distortion of the lens, we turn on the built-in "automatic distortion control" function of the camera before shooting, and the camera will automatically correct the recruitment according to the situation of your lens and save the JPG document. If you want to deal with RAW documents, you can use Photoshop's Camera RAW plug-in or the raw format editor provided by the manufacturer to deal with deformation. If you want to modify a JPG document in Photoshop, you can open Filter >; Lens correction "function, and then adjust the relevant parameters.
