How to focus well in night shots SLR ?

Weighted metering (3D distance metering) is used for night scene metering, and spot metering is rarely used.

Of course, the mode is A-gear.,The aperture is small.,F8 on,Try to be in the distance.,The point can be the center of the picture.,It can also be the center of the picture.,It's also a partial center.,If it's not a visible building.,It's best not to pull over.。。。 Because the lens can generally be infinitely far away, the farther you match, with a small aperture, the clearer the overall picture will be.

To have high accuracy in manual focusing, you need to rely on your eyes to see the focus point displayed on the camera. If you change the split image focusing screen, you can also focus very accurately.

Metering is generally not required to shoot night scenes correctly, because most of them use M gear. Instead, first estimate the **combination**, then take a photo, view**, and then adjust the **parameters according to the picture situation.

After the brightness of the picture is adjusted appropriately, the next step is to focus the problem. Under normal circumstances, manual focus should be the distance between the subject you want to shoot and the camera first, then turn the focus ring on the lens, look at the distance scale on the lens, and turn it to the distance scale you need.

There's another method that I use more often. That is, first use the AF mode to focus on the subject (such as buildings, trees, etc. in the middle of the ground, not infinity), and after the camera is in focus, switch the focus mode to MF manual, and then do not turn the focus ring again, because it is in focus at this time. Finally, adjust the composition and ** combination, and press the shutter to shoot.

1: When shooting at night, use a tripod, and then, use the wide-angle end.

<>3: Use the portrait shooting mode in special scenes, and the specific setting method is similar to that of handheld night scenes.

When you are shooting night scenes, you may have failed to shoot when you press the shutter, and one of the reasons is that the camera failed to focus, so the shooting function was locked, so the camera could not shoot, so what is the solution to this situation? Let's take a look at how to focus on SLR night shots!

(1) Look for a light-emitting object to autofocus

As long as there is light, you can focus successfully, although sometimes the glowing object (such as a street lamp, moon, etc.) will not fall exactly on the focus point, then we can focus on the luminous object by moving the focus point of the camera, but we must pay attention to the luminous object needs to be the same distance as the original focus, for example, originally wanted to focus on the top of the mountain (infinity), but because it is too dark to focus, then you can focus on the sky with a moon (luminous object), the result is infinite, then you can successfully shoot!

(ii) Use of external light sources to assist in autofocus

Sometimes, if the object to focus on is in the foreground, such as a gazebo at night, but because there is not enough light on the scene, the autofocus fails, then we can first maintain the autofocus, then turn on the flashlight to illuminate the object, and then set the camera to manual focus after half pressing to focus successfully. Once you're done, you can skip the focus step and concentrate on composing the shot and setting the aperture shutter. However, when using this method, it is important to pay attention to the position of the camera after setting the manual focus, and avoid moving the focus ruler (if any) on the lens, otherwise you will have to start the focus again.

(3) Directly switch to manual focus

The easiest way (but the most difficult for beginners) is to use manual focus entirely, which is more convenient for cameras with electronic viewfinders (EVFs) or with live displays, and some can even zoom in to focus to increase the chances of success.

(iv) Use preset focus points

This method is especially useful for shooting "infinite" scenes, such as taking photos of the starry sky. The principle is to do the second step mentioned in advance, but it can be done when the light is sufficient, focus the lens at infinity, and then mark the "focus at infinity" position on the lens (you can use a sticker), and when you use it, you can directly adjust it to manual focus and adjust the focus ring to the marker, which is very convenient and fast!

1. Focus on the light source with bright spots.

In night conditions, the camera cannot focus on blacks, so focus on the first vertical area with high brightness.

2. Focus on edges with high contrast.

The faces of objects in the dark are mostly black, for example, some buildings are surrounded by light, and it is easy for the camera to focus on these edges.

3. Use artificial light to focus first, and fix the large focus point.

Use a flashlight or strong LED to illuminate the object, and then use the camera to focus, but because artificial light will affect the metering, the metering and focusing must be separated, it is best to shoot in manual mode (M gear), you can first lock with **lock**, and then assist with the flashlight, press the shutter halfway to focus, turn off the flashlight, and complete the shooting.

4. If the focus point is broken and the composition is broken, you can focus first and then compose the picture.

Finally, using manual focus, lock the focus first, and then complete the composition by panning the camera, which is not affected by the autofocus by pressing the shutter.

5. When taking night landscape photos, it is best to extend the focus to infinity.

This ensures that the ** has a certain level of clarity.

6. Live view mode, there is always a suitable one for taking a few more photos.

Although it is feasible to shoot through the viewfinder for night shooting, it is more tiring because it may not be convenient to focus through a small viewfinder in the quiet of the night, but with the live view, you can use the magnification function and the ruler to focus manually, and you can get accurate focusing results. In addition, you may wish to take a few more shots in the focus accessory, there is always a suitable one.
