How does Canon 5d4 set the focus area?

1, the choice of focus position is not simply to find the best solution through calculation, it is related to our shooting intention and demand. Different focus positions can produce completely different picture effects:

2、? Basic principle: focus on the theme

If there are both clear and fuzzy parts in a photo, most people should pay more attention to the clear part.

In fact, clear-fuzzy contrast is a common means to distinguish primary and secondary pictures and express different themes:

The left picture highlights the sharp muzzle, and the right picture emphasizes "this is a foreigner"

3、? Landscape: the one-third rule

Landscape photography is not as simple as "small aperture+tripod+low ISO", and the choice of focus position also needs attention.

"One-third rule" is a well-tested and widely acclaimed focusing scheme in landscape photography: when there is no clear subject, focus on one-third of the depth of field.

In addition to the one-third rule, you can try another focusing scheme when shooting large landscapes: manual focusing is infinite.

4. Manual focusing is infinite.

Infinite focus, also known as pan-focus technology or hyperfocal distance focus, is also very common when shooting big scenes, which can make the whole picture in a clear range.

The specific operation is also simple. Switch to manual focus mode, then turn the focus ring to "infinity" and shoot with a small aperture.

Although infinity is the last gear, it is not to "screw the focus ring to the end". Infinite gears are generally located at the bottom of the focus ring, so please ensure alignment.

Step 5 focus on face and eyes

The eyes are the windows of the soul, the most expressive areas of characters' feelings and the most eye-catching parts in portraits. So, of course, pay attention to your eyes!

But don't be so rigid. If you are shooting a subject with a small face, such as the whole body and chest circumference, it is good to focus on the face. This focusing principle is also applicable when shooting other animals: small scale, focusing on the face; Large-scale, focus on the eyes.

6、? Long exposure: focusing on still life

The most common shooting themes of long exposure are running water and car streamer rails, which can shoot the motion trajectory of objects and make the picture dynamic.

In this kind of theme, in order to further highlight the sense of movement, it is often necessary to arrange a certain proportion of static objects in the picture to create a dynamic and static contrast.

Focusing on these static objects is naturally the best choice. After all, only static objects need to be clear.
