How to take wonderful photos in low light?
First, the type of weak light.
eyeable
These are the dark areas you will find during the day. Compared with the area with sufficient light, the shadow produced by large buildings or trees can be reduced to -2 light.
Low light level
After sunset, the area may still be visible, but it is too dark to capture.
dark
This is when only the brightest objects are visible at night.
Second, use a slow shutter for low-light photos.
So how do you shoot in low light? It all starts with the shutter speed, which helps to determine when light can enter the camera. The lower the setting, the more light will enter the sensor. But a slow shutter can also cause motion blur, especially without a tripod. So how do you take clear photos in low light?
According to experience, when ordinary people shoot by hand, they can shoot clear and unambiguous images as long as the speed is set to a small part of the focal length. It is worth noting that this rule only applies to full-frame cameras. If the same method is used on the sensor
For a 30mm lens,1/45s will be needed instead of1/30s due to the cropping factor of the sensor.
Third, the anti-shake function allows you to slow down the shutter speed.
When it is dark 1/30 or 1/40.
Seconds is not enough to take photos with correct exposure. But at the same time, no matter how slow the speed is, it will also lead to motion blur. So how to solve this problem with a camera? The answer is "anti-shake".
Nikon, Canon and even third-party manufacturers produce lenses that can reduce camera shake. Not all lenses have this function, but most kit lenses have this function. Anti-shake is very effective, up to 4.5.
Gear compensation allows you to shoot at115 seconds or less without motion blur.
Fourth, find a way to stabilize the camera without a tripod.
If you shoot a scene in poor light and don't have a tripod, some methods can help you keep the image exposed well and clearly. One is to tie the camera around the neck to keep it stable. Teaching can help you minimize camera shake.
In order to increase stability, you can also put your back against the wall, which can even eliminate the slightest movement when you shoot. But the best solution is to put your camera on the table or on the wall shelf to make sure it doesn't move when you take pictures.
Fifth, use a fast lens in the case of insufficient light.
When it comes to the maximum aperture that can be achieved, the choice of lens is very important. Choose the aperture as wide as possible, and shoot images in the dark. The value of f/ 1.4 will provide you with four times the light of f/2.8.
The maximum aperture of most packaged zoom lenses is between f/3.5-f/5.6. At the same time, the maximum aperture of professional zoom lens is usually f/2.8.
Or bigger. High-end fixed-focus lenses can be expensive. However, if you still start photography, you can also buy cheap lenses, such as Canon EF 50 mm f/1.8II. Many fixed-focus lenses can be realized.
F/ 1.4, even some of the most professional lenses can be reduced to f/0.95. The larger the aperture (the lower the f value), the faster the lens is considered.
Adjust ISO to get the correct exposure.
If you can't get the correct exposure just by changing the shutter speed and aperture, the best way is to improve ISO. ISO changes the sensitivity of camera sensors. The higher the value, the better the photos your camera takes in dim light.
But ISO is also difficult to control, because the higher the ISO, the more digital noise there is in the photo.
Seven, autofocus assist will help you use autofocus in the case of insufficient light.
Shooting in dark conditions may mean that it is difficult for your camera to focus automatically. Sometimes, the camera is too dark to determine the distance of the subject. Fortunately, any modern digital camera has the function of "autofocus assistant". very
The auxiliary light is usually located in front of the camera. If it is too dark, it will be turned on to illuminate the scene. You can activate this function in the camera menu. When you press the shutter halfway in the dark, it will open automatically.
8. Zoom in on the live view to focus in the dark.
In some cases, your autofocus assistant may not work, especially when your object is too far away. In this case, the flashlight may help to illuminate the scene to get the focus lock. It will also be helpful if you turn on live view and digitally enlarge the subject, so that you can see the details better.
