What does 45-degree angle mean?

The so-called 45-degree angle refers to the 45-degree angle formed by the line of sight of the camera lens and the front of the object or person being photographed. Generally speaking, just don't shoot directly or completely sideways, the angle is in the middle.

For example, the camera in the red circle below has a shooting angle of about 45 degrees:

When shooting a scene at a 45-degree angle, it is more conducive to showing the three-dimensional sense and spatial sense of the scene, and at the same time, it can make the subject have obvious perspective changes.

"45-degree angle" is a trick to take a selfie.

A fleshy face is a taboo for selfies, and shooting at a 45-degree angle can solve this problem. The hand-held mobile phone has an elevation of 45 degrees, and it is shot up and down at 30 degrees. At the same time, pay attention to showing three-quarters of the face. Everyone should remember not to be too partial.

Experience: my nose collapsed. After taking a 45-degree photo, my short nose became much straighter. Bao's face disappeared and his chin became sharp, highlighting the outline of his face.

Tip: If you don't have a selfie mirror and a front lens, you can use a mirror to reflect and stick it on the back of your phone. When you use it as a selfie mirror, be sure to stick it closer to the camera.

Look at the lens in the mirror before shooting.

Looking down at the phone lens will lead to looking down. The correct shooting method is to "look at the lens in the mirror", and the line of sight of the characters in the photo is upward. After deciding on the composition, look at the lens in the mirror when you press the shutter.

Lesson: Avoid looking down, but look deep.

Normal shooting

"45 degree angle" shooting.

First of all, both cameras and video cameras need lenses to image, and the lens that can focus on imaging is a convex lens. Observing a phenomenon, whether it is a camera or a video camera, the size ratio of the near image to the far image is larger when the object is pulled in than when the phenomenon is seen through the eyes, so it can be concluded that the image imaged by the camera and the video camera in the middle is more prominent and larger than that imaged by the human eye.

In addition, human eye imaging is two eyes, and there is a sight distance between them, so a stereoscopic image is generated, while cameras and camcorders are single-hole imaging, so they are flat and have no stereoscopic effect.

For the above two reasons, people usually take eyebrows, nose and mouth as the center line when taking photos or shooting, so the area near these three parts will be slightly enlarged when taking photos or shooting, but if the areas of these three parts are prominent, the amplification effect will be more obvious and there is no stereoscopic effect, so the human eye will not correct this enlarged part when watching photos and movies, and will think that this is a real image.

Therefore, it is concluded that a face with a small nose and sunken mouth and eyebrows will be more photogenic, while a face with a big nose and protruding eyebrows and mouth will be photogenic. It's like drawing on a balloon. Draw a face on a flat balloon. If this is a real face, then the image after the balloon is blown up is the face imaged in a camera or camcorder.

In addition, it is also based on this principle why it is better to take pictures from 45 degrees above or obliquely above. Because the shooting angle comes from above, the protruding part of the face relative to the lens is the eyes, and the nose and mouth will be pulled to a far position to reduce the magnifying effect caused by the protruding nose and mouth, and the chin will be reduced. Girls will look big, small and beautiful when they take pictures like this, but don't go too far. I've seen pictures with only the top of my head and eyes.
