When shooting in broad daylight, because the light is enough, we don't need to consider too many factors to maintain the quality of the photos, but if you shoot only in the daytime, it's really a pity! __________ Many night scenes and dark places are very beautiful. Cameras can even shoot light that can not be seen by the naked eye. So how to shoot in low light environment? Let's learn the following four basic low-light shooting techniques!
(1) Use of high ISO() ISO
Many novices are also afraid of raising ISO because it will increase the appearance of noise. But DSLR has made great progress in noise control, and the gradually popularized full-frame camera can effectively reduce the noise level. Therefore, in low light environment, we might as well make good use of the ISO of the camera to raise the ISO value to the appropriate level. In this way, the photosensitive element can increase the sensitivity to light under the same aperture shutter, so that your camera can also take a clear image.
ISO 3200 can also take good pictures.
(2) Enlarging the aperture()
Large aperture has two functions, one is to help shoot shallow depth of field, the other is to inhale more light. So in a low light environment, we can enlarge the aperture as much as possible to allow more light to enter. But some students will ask, what about the shallow depth of field? Not always want to make shallow depth of field effect ah! Right, the shallow depth of field under the large aperture will be more obvious, so we can use the following methods to "reduce" the shallow depth of field:
Wide-angle lens is used, because without the influence of long focal length, we can use large aperture to reduce the shallow depth of field effect. The farther away the background is from the subject, the more obvious the shallow depth of field is, so we can find an angle to reduce the distance between the background and the subject.
F/4 | ISO3200 - Large aperture with high ISO allows you to take clear pictures in low light.
(3) Use of wide-angle lenses()
Slow shutter speed in low light is the main reason for blurring photographs. Wide-angle lens can not only reduce shallow depth of field, but also reduce the requirement of safe shutter.
Safety shutter = 1/focal length safety shutter = 1 /
As can be seen from the above formula, the shorter the focal length, the slower the safety shutter required. So when using a wide-angle lens such as 18mm, the theoretical safety shutter is 1/18s, which is much slower than the safety shutter with a 200mm long-focus lens, so using a wide-angle lens can make the shutter open longer and absorb more light. 。 Note: The slowest safe shutter for a handheld camera is 1/50 seconds (regardless of your focal length).
F/4 | ISO3200 | 1/50s - Even if it's hand-held, you can take a clear picture with a wide-angle lens as long as the camera is stable enough.
(4) Keep your camera stable()
Because the shutter will be slow in low light, as long as your camera is stable enough, you can use long exposure to take wonderful pictures. Among the ways to maintain stability are: 1. using tripod 2. holding the camera steadily (such as holding your arms close to your body, holding your breath before pressing the shutter, etc.) 3. temporarily stabilizing the camera with other objects, such as putting it on. Stones, sandbags, paper towels, etc.
Low-light photography is the basic photographic skills that novice must learn. If you master the tips in it, you can make a wonderful and beautiful low-light world! ____________
