How to choose SLR focusing mode

Question 1: SLR focus mode and focus mode move AF freely, that is, choose focus organically (sometimes not what you want); Real-time focusing means that the machine is still in focus when the shutter is half pressed, which is suitable for shooting moving objects; There should be these modes in viewfinder mode, and real-time viewing is not necessary.

Evaluate, emphasize, etc. It should be a metering mode. Evaluation is to calculate the exposure according to the average working degree of the whole picture; For a single point, the exposure is calculated only based on the center point; The key points are similar to local points, and the exposure is calculated with reference to the whole map based on the central point or local point.

Multiple exposures refer to multiple exposures of the same picture, so the pictures exposed for multiple times will overlap.

Question 2: How to choose the focusing mode and exposure mode for SLR photography? Senior cinematographers generally choose fixed focus (center point) focusing and aperture priority automatic exposure mode (which can control the depth of field).

Question 3: How to adjust the autofocus area selection mode of Canon SLR camera? The default is multifocal, and no adjustment is needed. If you want to select the focus manually, you must set the focus mode to single focus.

Question 4: How to choose the best focusing method Usually, when shooting with a digital SLR camera, multi-point focusing is the most commonly used. According to the different camera grades, it is available from 3 o'clock, 5 o'clock, 7 o'clock, 9 o'clock to 45 o'clock. Why is the focus singular? Because in the whole picture area, the left and right focus points are symmetrical, and those with * * * are always singular. Multi-focus can generally cover most areas in the picture. When shooting, the camera will automatically select the focus it thinks. Sometimes, this choice is right, and sometimes, it is not necessarily the focus that the photographer wants. For example, when shooting a portrait, the camera may focus on the object behind it, resulting in a clear background and a virtual face. So can you choose one of the focuses manually? Of course, all digital SLR cameras have this function. By manually selecting the focus, the composition can be accurately controlled, and even if the subject is not in the center of the picture, the picture with clear focus can be obtained. Although it is convenient to choose the focus point, the focusing ability is not exactly the same in all these focus points. Generally speaking, the farther away from the center of the picture, the weaker the focusing ability. Therefore, it can be concluded that the center point must have the strongest focusing ability. Especially when the light is weak or the background is not contrasted, the central focus can often lock the focus, while other focuses can only be "bellows". Therefore, there is another focusing method for digital SLR: center point focusing. That is, the focus is fixed at the center point. If it is set to focus on the center point, does it mean that the subject must be placed in the center of the picture? Isn't that the same ingredient? This kind of worry is justified, but some advanced skills can be used to make up for this defect. Here are two methods for reference. First, put the subject in the center of the picture, and then press the shutter half way, at which time the camera will lock the focus. Then, half press the shutter (this step is the key), then move the camera and change the composition again, so that the focus of the picture is still on the object just now. At this time, press the shutter again, and you can get an image with accurate focus but different composition. Second, use the autofocus lock button. There is a button in the digital SLR called AF-L, which is autofocus lock. Similarly, the camera can also lock the focus by first placing the subject in the center of the picture, then half pressing the shutter, and then pressing the AF-L key after focusing. At this time, you can easily change the composition, and then press the shutter to complete the shooting. Pay attention to these two methods. First, we should keep the focal plane stable, that is to say, when changing the composition, we can usually only move the camera left and right, not back and forth. The reason is simple: moving the camera back and forth is equivalent to changing the distance between the camera and the subject, and the focus is definitely not accurate. Secondly, generally speaking, if you lock the focus by half pressing the shutter, you must pay attention to it. In this case, the exposure data will usually be locked. In other words, press the shutter after changing the composition, and the camera will not re-measure the light.

Question 5: Canon SLR, how to focus, focusing mode Canon digital SLR camera has four focusing modes.

They are a lens.

Artificial intelligence focusing

Artificial intelligence servo focusing

Manual focusing (MF)

These four types are used for focusing in different scenes. Let's take a look at their functions:

Single autofocus

In this focusing mode, as long as the shutter is pressed half a time, the red dot in the camera viewfinder will light up, indicating that the focus is completed.

If you want to adjust the focal length, you can dial the dial next to the shutter, select the focal length, and then press the shutter half-way. When focusing, press the shutter completely to get a clearly focused photo.

This focusing mode is mainly used to shoot static objects, portraits, landscapes and so on. , not suitable for shooting moving objects.

Artificial intelligence focusing and artificial intelligence servo focusing.

These two focusing modes are mainly used to shoot moving objects, such as games and animals.

When the camera is set with artificial intelligence focusing or artificial intelligence servo focusing, the camera will intelligently identify moving objects and make corresponding adjustments.

In the artificial intelligence focusing mode, the focusing operation is the same as single autofocus. However, if your subject starts to move, the camera will immediately find it and automatically switch to artificial intelligence servo focusing. Switching between these two modes is very fast, which ensures that you can get a clearly focused photo.

In the artificial intelligence servo focusing mode, the camera continuously focuses on moving objects to ensure the accuracy of focusing.

Especially suitable for shooting sports games that are difficult to keep accurate focus.

Manual focus

Most SLR lenses have switch keys for manual focusing and autofocus, and the words AF and MF on the lens are the switch keys for manual focusing.

In manual focus mode, you can select the focus by rotating the focus ring on the lens.

This mode is mainly used in low-light and low-contrast environments or scenes with complex graphics, because in these cases, the camera's autofocus system will fail and it is impossible to find the prepared focus.

In these cases, the best way is to focus manually, observe the scene to be shot from the viewfinder, rotate the focus ring on the lens and select the prepared focus.

Question 6: How to choose the display point in Canon SLR focusing mode can be adjusted at will. You can press the focus selection key in the upper right corner of the back of the machine, and then dial the front wheel or the rear wheel to adjust.

Question 8: How to choose the focus mode when shooting with a digital SLR camera? Can you take a perfect photo with accurate exposure? If you think so, you obviously underestimate the science of photography. The exposure is impeccable, but if there is no accurate focus, the photos taken are always blurred, which is obviously not acceptable. Therefore, a powerful autofocus system is designed in digital SLR. For digital SLR, focusing mode is not as complicated as metering mode. After reading the following text, you will naturally understand. Usually the most commonly used digital SLR is multifocal. According to the different camera grades, it is available from 3 o'clock, 5 o'clock, 7 o'clock, 9 o'clock to 45 o'clock. Why is it always singular? In fact, in the whole picture area, the left and right focus points are symmetrical, and those with * * * are always singular. Multi-focus can generally cover most areas in the picture. When shooting, the camera will automatically select the focus "what it thinks". Sometimes, this choice is right, and sometimes, it is not necessarily the right focus you want. For example, when shooting a portrait, the camera may focus on the object behind it, resulting in a clear background and a virtual face ... Of course, with the development of technology, the accuracy of digital SLR multi-point focusing is getting higher and higher. So can you choose one of the focuses manually? Sure! All digital slrs have this function. This focus mode can accurately control the composition, and even if the object you are shooting is not in the center of the picture, you can get a picture with clear focus. However, in some emergency situations, the speed of focus selection becomes a problem. It may be that the desired focus has not been selected yet, and the picture is fleeting. It seems that this focusing mode is more suitable for slow work and fine work. Although it is convenient to choose the focus point, the focusing ability is not exactly the same in all these focus points. Generally speaking, the farther away from the center of the picture, the weaker the focusing ability. So you can come to the conclusion that the center point must have the strongest focusing ability. What's the good of this? In the case of sufficient light, there may be little difference, but in the case of weak light or no contrast in the background, the central focus can often lock the focus, while other focuses can only be "bellows". Therefore, digital SLR has the most basic third focusing method: center point focusing. That is, the focus is fixed at the center point.

Question 9: How does the SLR switch to AF-C focusing mode? There is an AF MF lever in the lower left corner of the lens mount. That's also a button. Press and turn the thumbwheel, with the thumbwheel at the back.

Question 10: How to choose the focusing mode, namely af area mode, and choose the default area focusing when setting autofocus for SLR cameras? It is more accurate to use single-point focusing to compose a composition after proficiency.
