In the evening of the city, colorful lights and different kinds of billboards have always been the subject of night photography enthusiasts. However, for many beginners of photography, night scene is a very difficult subject to shoot, because exposure control is not an easy task, and there are many noteworthy techniques. Today, Xiaobian provides you with six points for attention that need to be done in night scene shooting and avoided in shooting. It teaches you how to shoot night scene quickly.
Six Major Events in Night Scene Photography
1. Turn on the long exposure function
In general, the exposure time of night scene is long, and the heat generated by CCD or CMOS will cause thermal noise when recording images. Now most DSLRs have the function of long exposure. When you take long exposure photos, the camera automatically takes a full-black image. The shooting time is the same as before, and then calculates the location of thermal noise points, so as to reduce the noise. The disadvantage of the long exposure function is that the waiting time may be very long. If you expose for 30 minutes, the noise reduction time will be another 30 minutes. It will take an hour to complete an exposure for 30 minutes. So pay attention to the camera power to decide whether to turn on this function.
Long exposure can reduce thermal noise.
2. Use the pre-elevation function of the reflector
The most important thing to shoot a night scene is to stabilize the camera so as to get a clear and sharp image. Therefore, the photographer should reduce the vibration of the camera in all possible ways. Some high-order SLRs have the function of reflecting mirror pre-lifting. Some cameras are called reflecting mirror lock. The principle is that the camera first lifts the reflecting mirror. When the shutter is pressed to shoot, the reflecting mirror does not need to be turned over to reduce the vibration when the reflecting mirror is turned over and make the picture clearer. In addition, the use of shutter line shooting can effectively reduce the vibration caused by the camera touching when the photographer presses the shutter. If there is no shutter line, you can also use the self-timer reciprocal function, after pressing the shutter, the reciprocal 2 to 10 seconds to shoot, will also have the effect of stabilizing the camera.
The pre-lift function of the reflector minimizes the vibration of the camera.
3. Use manual mode
Faced with the uneven lighting and strong contrast of the picture, the automatic photometry of the camera is easy to make mistakes. Although the photometry mode can be changed according to different circumstances, no one is smart, but the most convenient way is to use manual mode, depending on the environment, adjust the aperture and shutter automatically. For experienced photographers, they can also decide what aperture and shutter speed to shoot by themselves. Even beginners of photography, in today's digital photography age, they can see the effect of shooting in real time. If one photograph is not good, they can shoot the second one, until they are satisfied, and they can also practice exposure judgment and aperture for beginners. Why not use the shutter?
4. Pay attention to the picture level
When shooting night scenes, because of the use of tripods, the photographer's eyes do not need to look at the viewfinder for a long time, so many photographers only pay attention to the operation of the camera, but ignore whether the level is skewed. And part of the environment is very dark, it is very difficult to see clearly the picture of the viewfinder, which affects the accuracy of the composition. A photographer can take a picture first to see if the level of the current composition is skewed, and then correct it. If the final photograph is really skewed, some image processing software can be used to correct the level, but some edges will be cut off, so it is better to solve the problem first.
Even if you take a very good picture, if the level is skewed, it will completely destroy the beauty of the picture.
5. Shooting RAW format
When we shoot night scenes, the multicolored lights will make the light source very complex. The photographer may not be able to take the desired effect immediately. In many cases, it needs post-processing to get a better image. The JPEG format commonly used is compressed after the internal processing of the camera. Product, data deletion and loss, the quality of post-processing decline, so the best use of RAW format for night scenery shooting. RAW format has more processing space in later processing, such as the change of white balance, and can also reduce the loss of detail when changing brightness.
RAW format is convenient for post-processing pictures, if you can change the white balance arbitrarily.
6. Shooting with a small aperture
The tripod will certainly be used to shoot night scenes, so you can ignore the problem of too slow shutter, no matter how small the aperture is. Small aperture not only can fully play the quality of the lens and shoot sharp pictures, but also can make the depth of field larger. The whole picture is in the focus range, which is helpful for picture expression. If there are street lights or light bulbs in the picture, the small aperture can also make these lights produce starlight, making the picture more gorgeous.
Starlight is produced by light in a small aperture (F22).
Six Escapes of Night Scene Photography
1. Don't shoot with your hands.
Tripods must be used to shoot night scenes. Place the camera on a stable plane even without a tripod. No matter whether you have a pair of "plaster hands" or not, no one can hold a camera for a second or more without hand shocks at all. So if you want to shoot a night scene, you should buy a stable tripod.
2. Brightness optimization should not be turned on
This function has different names in different brands of cameras. This function can increase the brightness of the dark part and reduce the brightness of the highlight part. However, when shooting night scenes, many areas of the picture are black, the optimization function will reduce the contrast of the photos. Even if the photographer had planned to take low contrast style photos, post-processing of the effect is very simple and does not need to turn on the function before shooting.
3. Don't use autofocus
When shooting a night scene, it is often in a dark place. If auto-focus is used, the focus system will often have the situation of "pulling bellows". That is, the lens can not find the main body and rotate back and forth continuously without focusing. Even after focusing is determined, it may not focus accurately on the subject. So the photographer might as well use manual focusing to set the focus at infinite distance, as long as the depth of field is large enough, the whole picture can also be in a clear range.
Manual focusing is more reliable in the dark than automatic focusing.
4. Don't use flash
When you shoot at the seaside, you will always see many people shooting night scenes with digital cameras and flash lights. This is a mistake that people who don't understand photography easily make, because the flash of the camera can't illuminate the tall buildings in the distance at all. Even if you just want to illuminate the near scenery, the white light of the flash will be completely different from the surrounding light. It seems out of place. Unless you're shooting a night scene portrait, you'll use a flash to illuminate the subject, and it's skillful, so don't use a flash to illuminate the scene on the other side.
5. Don't use shockproof lens
Shock-proof lenses help with lower shutter speeds when handheld, but when shooting night scenes, they are usually not handheld, so this function is completely useless. Not only is it useless, it can even affect imaging. Because the principle of anti-seismic function is to detect the vibration of the camera, when the camera uses the scaffold, the anti-seismic system may make unnecessary compensation for the camera, but will reduce the imaging quality. Although some of the shockproof functions of the lens will have the scaffolding mode, automatically detect whether the shooter is using the scaffolding, but you will not know whether the lens successfully detects the scaffolding, so it is better to shut down the anti-seismic function itself, in fact, it is only a matter of hands.
Although the opening of the shockproof function on the scaffold may not have a practical impact on the quality of the picture, if the picture is blurred, it will be irreparable.
6. Don't shoot in total darkness
Usually night scenes are taken 10 - 30 minutes after sunset, during which time the sky will be very blue and it will be easier to take wonderful pictures. If the sky is too dark to shoot, the sky will be very deep, and the contrast caused by street lights and billboards in the city will increase, making it more difficult for the photographer to control exposure.
