Group photo, activity photo, how to focus?

For a big group photo, it is recommended to choose the shooting distance according to the number of people. Of course, it is inconvenient to be too far away, but it can't be too close.

Whether each face is clear or not can be controlled by focusing. Of course, we still look at it according to the situation:

Simply put, if only a row of people use it to shoot vertically (that is, the most common group photo), then just put everyone in the picture according to the equipment at hand, and the proportion of people near is larger, and the scenery far away is farther. Focus only on the upper body of the middleman.

However, if there are many rows of people, or if everyone is not on the same plane but separated from the front and back, if the shooting distance is not well matched with the aperture and lens focal length, some people will be "blurred". The following points should be understood:

Wide-angle lenses have greater depth of field. After the aperture is reduced, the depth of field is larger. Being farther away from the subject can increase the depth of field behind the subject.

People have the most problems of separation before and after. At this time, it is best not to be too close to people, use a small aperture or a wide angle, and be careful not to deform when using a wide angle.

If there are several rows of people, there are usually many people in each row. At this time, I believe you have retreated far enough. Turn down the aperture, use f8 outdoors, and ensure about 5.6 indoors.

When taking pictures, leave the focus to the camera's focusing system, or set it as the center fixed-point focus, and take the one with the most appropriate expression as the focusing center.
