Four basic shooting skills in low light

Because there is enough light to shoot in broad daylight, you don't need to consider too many factors to maintain the quality of the photos, but it would be a pity to shoot only during the day! Many night scenes and dark places are very beautiful, and the camera can even capture light that is invisible to the naked eye. So how do you shoot in low light? Let's learn four basic low-light shooting skills!

(A) the use of high ISO

Many novices are afraid to improve ISO, because it will increase the appearance of noise, but in fact, DSLR has made great progress in noise control, and the gradual popularization of full-frame cameras can effectively reduce the noise level. Therefore, in the low light environment, we might as well make good use of the ISO of the camera to raise the ISO value to a suitable level, so that the photosensitive element can increase its sensitivity to light under the same aperture shutter, and your camera can also take clear images.

(2) Enlarge the aperture

Large aperture has two functions, one is to help shoot shallow depth of field, and the other is to absorb more light. So in low light environment, we can enlarge the aperture as much as possible to let more light in. But some students will ask, what about the depth of the scene? I don't always want to shoot shallow depth of field! Yes, shallow depth of field will be more obvious under large aperture, so we can "reduce" shallow depth of field in the following ways: use wide-angle lens, because there is no influence of long focal length, we can use large aperture to reduce the effect of shallow depth of field.

Pay attention to the distance between the subject (focus) and the background. The farther the background is from the subject, the shallower the depth of field is, and the more obvious it is. You can find an angle to narrow the distance of the background.

(3) Use a wide-angle lens

The slow shutter speed in low light is the main reason for the blur of the photo. Using a wide-angle lens can not only reduce the shallow depth of field, but also reduce the requirements for the safety shutter: the above formula Safety shutter = 1/ focal length shows that the shorter the focal length, the slower the required safety shutter speed. Therefore, when using a wide-angle lens such as 18mm, the theoretical safe shutter speed is 1/. Compared with the safety shutter of 1/200 seconds with 200mm telephoto lens, it is much slower, so using wide-angle lens can make the shutter open for a longer time and absorb more light.

Note: The slowest safety shutter for hand-held cameras is 1/50 seconds (regardless of your focal length).

(4) Keep the camera stable

Because the shutter will be slow in low light, as long as your camera is stable enough, you can take wonderful photos with long exposure. The ways to keep it stable are:

1. Use a tripod

2. Hold the camera steadily (for example, put your arm close to your body, hold your breath before pressing the shutter, etc.). )

3. Hold the camera temporarily with other objects, such as stones, sandbags, paper towels, etc.

Low-light photography is a basic photography skill that beginners must learn. As long as you master the tricks, you can shoot a wonderful and beautiful low-light world!
