Focusing skills of portrait photography

Photography skills ":portrait photography focusing skills sharing;"

Shooting portraits in any posture and at any angle is basically aimed at focusing the eyes.

It is very important to focus your eyes accurately when shooting portraits. If the eyes are out of focus, the whole photo will be soft and lose focus. No matter what pose the photographer poses, no matter what angle he shoots from, he should focus his eyes accurately. Especially when shooting with a large aperture, the depth of field becomes smaller, and a slight shift in the focus position will cause the eyes to defocus, so photographers should pay attention. When shooting with a small digital camera, as long as you can focus on a certain position of the face, you don't have to pay too much attention to the focus position. However, when using a high-pixel digital SLR camera, the out-of-focus phenomenon will be particularly obvious when zooming in because of the high resolution of the picture. In addition, because the image sensor of digital SLR camera is very large, it is easy to blur. When shooting with a 35mm full-frame camera, the blur is greater, so the requirements for focusing are stricter, and even attention should be paid to which part of the eye should be focused.

Preventing jitter is a taboo in portrait photography.

Many photos that are considered out of focus are actually faults caused by jitter.

If you carefully observe those photos that are considered out of focus, you will find that many of them are not sharp enough because of jitter. Out-of-focus and jitter are basically irrelevant, but both of them will affect the clarity of photos. Pay attention to portrait photography in particular. In addition, we should also pay attention to the subject jitter that may occur at the same time as hand jitter. As a shutter speed reference without hand jitter, it is generally considered as 1/ focal length = safe shutter speed, but this statement does not take into account the influence of subject jitter. In portrait photography, it is necessary to consider that the subject is also moving, and then determine the appropriate shutter speed.

How to set the camera to get the ideal focal length?

Camera settings for ideal focusing effect:

1. Set the camera to aperture priority automatic exposure mode. It is very important to control the focal length (depth of field) in portrait photography. So choose Av (Aperture Priority Automatic Exposure Mode) from the shooting mode dial, and let the photographer control the depth of field according to his own intention. It is easier to control the focus range by using Av mode with the aperture value determined first.

2. freely determine the ISO sensitivity. ISO sensitivity should be freely selected according to the shooting situation. Setting it to automatic is basically no problem, but in order to better understand the relationship between shutter speed and aperture, it is best to choose a certain sensitivity to get used to shooting.
