What are the differences between the three focusing modes of Canon camera?

Our current digital SLR cameras are equipped with advanced autofocus systems, but it is often difficult for novices to understand. Whether you are an entry-level or a professional camera photographer, you know that how to use the autofocus system effectively is the essence of getting clear images. A very blurred image will ruin a photo, and you can't even fix it later. Some awesome experts often end up converting images into black and white to hide their focusing problems. If you learn to focus correctly, accurate focusing can get clearer images, which every photographer should learn. I know that some photographers will argue with me, and sometimes blurred images will produce a "creative" appearance, which is a fallacy. Because I am a Nikon user, I will pay more attention to Nikon's digital SLR camera.

1) Scene # 1- Shooting outdoor sports

You are shooting outdoor sports in autofocus mode and autofocus area mode. Do you like football? Let's start by choosing the appropriate autofocus mode. Obviously, it is impossible to use a separate area /AF-S mode, because you need to constantly adjust the focal length of the camera and press the camera shutter /AF button. So be sure to use AF-C or AF-A mode. I won't let the camera decide how to focus, so switch to AF-C mode in this case. What about AF-area mode? Should we use single-point autofocus area mode, dynamic autofocus area mode, group area autofocus mode or 3 d tracking mode? Personally, I will choose 3 d tracking mode, so that my camera can process the tracking research object while composing the lens. If you find that 3 d tracking is not a good exercise, you can't track your object correctly, and then switch to the focus with a relatively high number of dynamic AF area modes, especially if you are close to the action. If you only want to track the object closest to the camera, atrial fibrillation in the group area works well. This is the profile setting I will use:

Auto focus mode AF: c focus area mode: 3 d tracking, dynamic auto focus area custom setting-> Dynamic autofocus area: 2 1 or 5 1 user-defined settings->; AF-C priority selection: release priority

2) Scene # 2- Taking a portrait outdoors

You can use any autofocus mode when shooting outdoor portraits during the day.

Auto focus mode: S-C or af focus area mode Single point af area: custom setting-> AF-S gives priority to user-defined settings-> AF-C priority selection

3) Scene # 3- The photographer is indoors

Shooting indoors is also challenging, especially when the light is dark. If the indoor light is not good, I will use AF-S mode to ensure that my AF-Assist helps me when necessary. You can't use AF-C mode. AF-A mode should also be suitable for these situations, but I still choose AF-S mode. As far as AF-Area mode is concerned, I will choose single-point AF-Area mode and center-point autofocus.

Auto focus mode: af-S focus area mode single-point af area customization setting->; AF-S priority selection

4) Scene # 4- Taking pictures of birds flying

It is very difficult to photograph birds, because it is difficult to predict their behavior, and their speed is often very fast. As I have pointed out above, the focal points of continuous shooting /AF-C mode and selected group AF mode or dynamic AF- area mode are 9 and 2 1 respectively. I tried using 5 1 focusing and 3 d tracking mode, but found those focusing slow and unreliable. In fact, the central focus usually gives you the best effect. If you are a bird and it is difficult to get it through the initial focus, try group area autofocus (if available).

Auto focus mode af: c focus area mode: dynamic focus area customization->; Dynamic autofocus area: 9 o'clock and 2 1 point custom settings-> AF-C priority: release shutter

5) Scene # 5- Shooting Landscape and Architecture

Landscape and architecture, all focus modes are good, but I prefer to turn to AF-S mode because there is no tracking.

Auto focus mode: af-S focus area mode single-point af area customization setting->; AF-S priority selection

6) Scene # 6- Shooting Large Animals/Wild Animals

When shooting large animals, I will be in continuous shooting /AF-C mode and use dynamic AF-Area or 3 d-tracking mode. Animals are usually not as fast as birds (although sometimes they can be faster), so unless you are shooting fast movements, I will only choose the focus with the highest number of dynamic AF-Area or use 3 d-tracking.

Auto focus mode af: c focus area mode: dynamic auto focus area d tracking /3 custom settings-> Dynamic autofocus area: maximum autofocus points or 3 d custom settings->; AF-C priority: release focus

7) Scene # 7- Photography Crowd

I am often asked how to focus on shooting a small group of people. Before I talk about focus mode, let me point out some important things. If you use a standard or telephoto lens, be sure to be careful about the distance when shooting with a large aperture. If you are too close to the group and shoot with a large aperture f/1.4- f /2.8, there may be only one or two people paying attention to others, unless everyone is on the same plane. The solution is to either change your smaller aperture f /5.6 or f /8 or retreat/stay to increase your depth of field, or both are parallel. If you want to blur the background and aperture, your only choice is to put everyone on the same plane, parallel to your camera. Auto focus mode, if you are shooting in broad daylight and any atrial fibrillation mode works well, I will choose single focus AF-Area mode.

Auto focus mode: S-C or af focus area mode Single point af area: custom setting-> AF-S priority: pay attention to custom settings-> AF-C priority: release focus
