How to shoot the night scene with a camera At present, many high-end digital cameras provide shooting modes of P (automatic), A (aperture priority), S (shutter priority) and M (manual). In addition, most digital cameras provide scene shooting modes, the most common modes are night scene mode and macro mode, and some digital cameras provide more detailed and rich scene modes, and even can obtain functions such as night and late-night shooting modes. Generally speaking, satisfactory results can be obtained through this night scene mode. For most novice digital cameras, shooting night scenes is the simplest, feasible and guaranteed method. However, it should be noted that some digital cameras cannot flash synchronously in night view mode.
Computer-synthesized secondary exposure
When shooting at night, the ambient light is weak and the contrast is large, so digital cameras use electronic photosensitive elements. Due to technical limitations, the information obtained is easily affected by noise, and the details in the dark part are weak. Usually, digital cameras can't do the second exposure operation like traditional cameras, which is a common skill of traditional cameras when shooting at night, but this problem can be solved by computers:
Firstly, determine the file size and format of the shot image and the settings on the camera, and make clear the composition, and then take photos before night when the light is still good; Keep the original focal length unchanged. When the light is on, set the exposure value of the digital camera. Please make sure not to change the focal length of the lens or change the file size format of the image, and then shoot to get another photo. Input two photos into a computer and use image processing software (such as photoshop or photoimpact) for post-synthesis processing. In this way, high-quality night images can be obtained simply and conveniently. This method can also be used to make beautiful night photos of people.
Focusing problem of night scene shooting
At present, there are few digital cameras with fixed focus mode, which are basically products below 2 million. Many other digital cameras adopt the focusing mode of combining auto-focusing with manual focusing. Each focusing method has its own characteristics and applicable objects, such as numerical adjustment manual focusing and focus ring manual focusing. Numerical adjustment Manual focusing can achieve accurate focusing by adjusting the "distance" value in the LCD screen. This focusing method is troublesome to operate and requires high judgment of distance, but it may be effective for shooting night scenes.
Generally speaking, non-SLR or quasi-SLR digital cameras still need to improve the accuracy and speed of autofocus. Because it is difficult for ordinary digital camera focusing sensor to accurately focus on scenes with low contrast and low brightness, when focusing on night scenes, please try to focus on bright scenes, and then lock the focal length for composition.
Unexpected white balance
Different from traditional camera shooting, digital cameras do not achieve white balance by adding color filters, but only adjust the color of the whole image through built-in programs. General digital cameras have several white balance modes to choose from, some digital cameras also provide white balance numerical adjustment (color temperature adjustment), and some higher-end digital cameras even have custom white balance function, which provides photographers with a broader creative space.
When taking photos at night, if the white balance adjustment is not adopted, the light waves generated by floodlights decorating buildings and landscapes will display more beautiful colors on the photosensitive elements (because the human eye can automatically correct the color balance), while the night sky will display more amazing and bright colors on the photosensitive elements. If the automatic white balance adjustment is adopted, the gorgeous colors of the scenery will be lost, and the photo level will appear monotonous and tasteless. Readers who pursue special effects can try different white balance shooting effects and have unexpected gains.
Mastering the night shooting skills of digital cameras requires a lot of practice. Readers can explore many interesting places in shooting practice according to the functions and characteristics of their cameras, and give full play to their creative inspiration to show the beauty of the night.
Precautions:
Generally speaking, digital cameras are not equipped with a lens hood, so be careful when taking pictures near the light source. You can use simple objects for occlusion.
When shooting, you should choose lcd (liquid crystal display) for framing. Considering the problem of power consumption, the compromise method is to use optical viewfinder to view the scene and use lcd to confirm the composition. When shooting in a dark environment, the display screen can't work well, so we should choose an optical viewfinder to view the scene.
When shooting outdoors, you should bring enough batteries and mobile storage. Use Lcd screen when not shooting.
Be sure to bring a tripod. Hand-held shooting will greatly affect the quality of the final image. Use the self-timer function or remote control shooting to reduce the influence of jitter.
The effect of lcd screen display is not the final photo effect, but it is generally much brighter than the actual photo, so it needs to be observed and judged accurately on the computer.
