Skills sharing of portrait lens 50mm fixed focus lens

When it comes to taking portraits, I believe many photographers will say 50 fixed focus first. So why do some people like 50 fixed-focus lenses? What is the best way to shoot people with this lens? What should I pay special attention to when using a 50 fixed-focus lens? At the photography knowledge sharing salon held by Chengdu Photography Club on August 20th, Mr. Wang Kai shared it in detail. We also sort it out and share it with more film friends.

To understand the use of portrait lens, we must first know the four effects of lens focal length on the picture.

1. focal length affects viewing angle.

2. The focal length affects the perspective relationship.

3. The focal length affects the depth of field

4. The focal length will affect the telepresence.

The first three are easy to understand. The shorter the focal length, the wider the viewing angle. Wide-angle lenses are more likely to highlight the three-dimensional sense of space, and telephoto lenses are more likely to show a sense of space compression. The longer the focal length, the easier it is to have a shallow depth of field.

So what is telepresence? This is abstract, but it is not difficult to understand. For example, at the same activity of Chengdu Photography Club, everyone photographed the same model. The teacher instructed everyone that this action can shoot the upper body of the character and show the mood of the character. Then everyone took a bust with different focal lengths. Although these are all half-length photos, the viewer's feelings are different.

Some photos just have a sense of bringing in, which allows you to walk into the environment or emotions of the characters. There are also some photos, which feel that they only record the environment. This is telepresence. The telepresence needs the photographer's constant practice and shooting summary. This is why the master photographer is the decisive point of the master.

Back to the 50-focus lens, this is the visual perspective feeling closest to the monocular perspective feeling of the human eye. So the best telepresence of 50 fixed focus is to shoot a bust or a bust? Or close-up?

Let's think about it. What is the best communication distance between us face to face? This distance is about 1.5 meters. And the dialogue distance of 1.5 meters, most of our attention is on the upper body of the character. That is, above the waist This is the best lens that can be displayed by telepresence with 50 fixed-focus lenses.

Then tell me. Can I only take a half-length photo with a 50-focus lens? This is not absolute. If you want to retreat a little, about 2 meters will show the environment. Or go deeper and take some close-ups. It is also possible. The key lies in the choice, and the change of the relationship between the emotions and the environment of the characters you want to express.

Understanding and skillfully using the focusing lens requires constant practice. The practice of Chengdu Photography Club on focal length is constantly updated.
