How do I set the focus mode when shooting dynamic portraits on the Canon 70D?

1. It doesn't matter what kind of SLR you use to take portraits, any SLR can take portraits, you don't need to point out that you are using Canon 7D. But since you've already said 7D, you might as well say a few more words, 7D is so old that I can't even remember what year it was the machine, maybe 10 years, 10 years ago I probably was still using the Kodak DX6490. Well,It's a bit far,7D is not only old,It's also a speed machine,It can be said that a lot of things have been sacrificed for speed,Such as picture quality,So in general home、Shooting people, etc.,7D speed and control you can't use,The picture quality is not as good as buying a 3-4K entry machine now。

Therefore, if you happen to have a 7D at hand, it is not bad to use it, so it should be practiced, otherwise it is recommended to buy a 3-4k entry opportunity.

2、Compared with the fuselage,What is more important for shooting people is the lens,The cheapest portrait head in the Canon system is none other than a small spittoon,1kLess**,It can give you acceptable image quality、Focal and bokeh ability,Further up,Canon85mmThere are several specifications,In short, the expensive one is better than the cheap; There is also a Canon 135mm shoot that is also very good; In terms of zoom, 24-70mm, 70-200mm lenses can shoot people.

3. Learn to use good lights, this is not clear in a few words, it is more difficult than choosing a lens, in short, the light of the model's face is better, if the background light is very bright, but the model is in the shadows, you must use the light, flashing, flashing, filling light, fill light or something, otherwise the model's face is black.

4. In a certain later stage, the skin tone of the Canon is already very good, but the defects, spots, and other spots on the face still need to be repaired.

Theoretically, if the subject's movement is regular, the AI Servo mode should be used to focus, or if not, the AI Focus mode should be used.

Summary. When you turn on the parameters in M mode, you can see the value of [F16], which is the aperture value. The aperture value can be used to adjust the depth of field and the amount of light entering the light, which in turn affects the amount of light.

f is the aperture of the aperture, just like the cat's eyes, the smaller the aperture value, the larger the cat's eyes, so the more light it receives, the brighter it is, and the distant background will be blurred. On the contrary, if the aperture value is small, the more you press **, the background will not be blurred.

How to adjust the parameters of Canon 70D video recording mode.

In order to easily view the parameters, we can set the shooting scene to [M manual transmission].

Then you can see the shutter, aperture, ISO and other values in the right shoulder screen, what about modifying it in**?

On the contrary, if the aperture value is small, the more you press **, the background will not be blurred.

If you are shooting portraits, it is recommended to use a wide aperture, so that the background blur is strong and the characters can be more prominent; If you are shooting landscapes, you can use a small aperture to shoot the best of the best.

The [1 125] on the left is the speed of the shutter, the faster the shutter speed, the darker the ** shot, and vice versa. For night scenes and water currents, the shutter speed is slower; When shooting high-speed objects such as sports, news, and events, the shutter speed should be fast. Half of the ordinary hand-held photo [1 125] can be satisfied.

Finally, let's talk about [ISO sensitivity], the minimum ISO value of a DSLR camera is 100, which is also the most commonly used value, if the ** of the next shot is darker, you can increase the ISO value, so that the shot will become brighter, if the value is too high, there may be noise, so try to reduce the value Oh, video.

3.It should be noted that the mode dial cannot be in M gear at this time. Pay attention to things:

You need to use a high-speed SD memory card, the faster the better, to ensure the security of the photographic data.

SLR parameter settings:

Shooting mode: Shoot portraits, you can use M file.

Metering mode: Spot metering and evaluative metering are available. When shooting portraits, use a single point to focus, and if you want to shoot people clearly, focus on the person's eyes.

Aperture (F), shutter (T) and sensitivity (ISO) can be adjusted according to the scene environment.

If you shoot handheld, the shutter denominator is recommended to be equal to 125, because if it is too small, it is easy to shake your hands, resulting in ** void. Also, if you want to shoot snowflakes falling instead of the snow line, you should also use the shutter speed (use the slow speed to shoot the snow line).

There are three ways to do this.

1. In AF (AF) mode, adjust the lens focus mode to MF (manual focus) mode after focusing, lock the focus point, and recompose the shot. The advantage is that it is easy to operate, and the disadvantage is that it is easy to defocus when shooting dynamic subjects.

2. Set the camera to live view mode, that is, LCD frame mode, and click directly on the touch screen to select the focus focus.

3. Single-point autofocus (manual selection) and area autofocus (manual selection) can freely select 19 AF points, and the specific method is:

1) Press the AF point selection button so that the entire AF area lights up in red and enters the ready state.

2) (When holding the machine horizontally) Use the main dial when moving the AF point left and right.

3) Use the quick-control dial to move the AF point up and down.
