How to choose the correct focus mode when shooting?

If high-quality images are based on accurate photometry, then choosing the correct focusing method can help us get clear images, which is exactly one of the key links to take good photos. So, here are the focusing modes of Canon and Nikon cameras and their specific applications.

Single autofocus should be used when shooting still objects.

Single autofocus, Canon camera is called ONE SHO), and T and T Nikon cameras are called ONE servo autofocus (AF-S). This autofocus mode is one of the most commonly used focusing modes in landscape photography, especially suitable for shooting still objects. All kinds of scenery, trees, mountains, seascape, sunset, falling, and so on. Of course, the single autofocus mode is not only suitable for landscape photography, but also suitable for shooting still portraits. For example, when looking for a model to shoot, you usually choose to pose, and posing means that the photographer instructs the model to do some actions or poses and then the photographer shoots, instead of the model moving all the time and then the photographer takes a snapshot. Of course, taking snapshots is also possible. When the photographer guides the model, he can capture the expression of the model at that time and shoot it in other focusing modes.

In autofocus mode, the camera stops autofocus after successfully pressing the shutter for half a time. At this time, the composition can be readjusted by keeping the shutter half pressed. The focus of the photos taken in this focusing mode is clear, and the composition is more flexible, so you don't have to stick to a single focus. About how to set the focus mode.

Here are the focus mode settings for Canon and Nikon cameras:

How to set the focus mode of Canon camera: Press the AF button and turn the main dial to select a focus mode.

How to set the focus mode for mid-to high-end Nikon cameras: When the focus mode selector selects the AF icon, hold down the AF button and turn the main dial at the same time to switch between the three focus modes.

The operation method of setting the focus mode of entry-level Nikon SLR camera: press the info key to open the information display on the display screen, press the I key to enter the information display setting state, press the up, down, left and right keys to select the icon of the focus mode, press the OK key to confirm, so as to display options such as AF-A AF-S AF-C, and then press the left and right keys to select one of them.

Select continuous autofocus AI servo (continuous servo autofocus mode AF-C) when shooting moving objects.

This focusing mode is most suitable for shooting moving objects. In this autofocus mode, when the photographer half presses the shutter to focus, the camera will automatically switch focus to keep the moving object in focus, and the camera will keep focus. If the position of the subject changes greatly during this process, as long as the mobile machine keeps any focus covering the subject, it can continue to focus.

When shooting a subject with uncertain motion, AI FOCUS (AF-A) should be selected.

When we aim the camera at children or animals, we don't know what these subjects will do next, or whether they will suddenly move next, so if we use single autofocus mode or continuous autofocus mode, the effect will sometimes be blurred. At this time, we can choose to use the artificial intelligence autofocus mode. Artificial intelligence autofocus mode is an artificial intelligence mode, which is mainly used in shooting situations where it is impossible to determine whether the object is still or moving. In this mode, the camera will automatically select single autofocus mode or continuous autofocus mode according to whether the subject is moving or not.

For example, when you shoot a still animal, you use a single autofocus mode, but when you press the shutter, the animal you shoot suddenly moves, so the next photo you take will be blurred. However, if you use smart autofocus, the effect will be different, because the smart autofocus mode will help you modify the focusing mode at the moment when the animal moves, so the photos taken will not be blurred, but will show the process of a small animal moving.
