How big is the aperture for 20 people to take a group photo in creative formation?

You need to know the intensity of ambient light and the shooting distance to calculate. Generally, the aperture value should be controlled at around 5.6-8. If we only want the image of the "main character" to be clear, our thinking is just the opposite of one, two and three above. Because as long as "catching one person" is not as good as the rest, we can completely make the main character and other characters "unequal in distance", that is, deliberately open the distance; Use a larger aperture to appropriately blur non-main characters; By using point focus, the non-main characters and the main characters form a contrast between reality and reality, and the requirements of highlighting the main characters are realized.

The essence of multifocal is to "take care" of the elements entering the picture as comprehensively as possible to ensure that all the people taking pictures are clear.

Expanding information Many movie friends think that "we should be clear before and after, so we should use multifocal mode", which is a typical example. No matter how many focal points a camera has, there is only one focal point. If you want to make the figures in the front and back rows clear, it is related to the "depth of field" problem, and you can narrow the aperture to shoot. Please don't confuse the two.

Therefore, please adopt the "single focus mode", and then adjust the focus to the foreground 1/3, and use the basic principles of the foreground depth of field and the back depth of field to allocate the depth of field reasonably. For example, a photo of five rows of people should focus on the second row of people.
