And traditional reverse picture digital camera as photographic exposure tolerance symbol is very small, even with the 1/3EV differences, the imagery is also a significant difference.
Therefore, accurate to the scene of exposure control is digital camera at night photography.Now, many high-end digital cameras not only provides P, A, S, M exposure modes, also provider bracketing mode (such as close-mode, night mode, etc.).
This type of program bracketing mode according to the type of the photographs, make the appropriate exposure setting, generally are able to obtain satisfactory results. Note that part of the digital camera at night exposure mode cannot synchronize with flash photography.If using P, A, S, M exposure modes for night photography, then it is better to use a telephoto lens on the main light in the scene or medium density shade for spot metering, and then to return to the composition status reset exposure and exposure compensation.
For night filming, low illuminance environment, contrast, digital camera PC components (i.e. photoelectric sensor) of the resulting information is vulnerable to the effects of noise, dark detail is relatively weak. Therefore, a computer friends the best reference multiple exposure night photography: first determine the photographic image file size and format and the camera's settings, and then clear the composition, and then compare the light values soft bright right time, taking one sheet; keep the camera focal length does not change the composition, lanterns, use another camera metering, and then set the exposure value on your digital camera (minimize camera operation, do not change the lens focal length and change the image file size format), shooting; late into the computer, using image processing software will handle the two image synthesis. Visualization of late, you can simple and convenient access to high-quality stock images.Due to the smaller digital camera lens, the smaller the aperture (f value larger), the scenario of dot laser module is in the photo as in the beautiful stellate light, pursue special friend may wish to try.
Of course, since digital cameras have a shoot that show features; therefore, you can take different exposure value comparison for shooting, find the best exposure value.How to conduct accurate af
Except for a small proportion of low end digital camera with fixed focus mode, available in many digital cameras have been used the auto focus and manual focus with AF mode.
Each focus mode have corresponding characteristics and the application object, such as a spin-manual focus and manual focus ring. Spin-manual focus through the LCD display of distance spin to achieve accurate AF, AF mode operation in trouble, on distance judgment requires higher, but for shooting night such subjects, but efficient; whereas the focus ring manual focusing adhering to the traditional manual focus mode, meet the habit of using manual focus, but users must be made through the LCD display to confirm that, not suitable for large scenes shot, especially at night.Digital camera auto focus control system compared to traditional camera auto focus control system, there are many worthwhile improvements.
Since the AF sensor for low contrast and low brightness of the scene to accurate autofocus, autofocus for night shooting, try to focus on the bright scenes, alignment char before locking the focus framing. It is important to note that the lens changes affect the AF and AF switch to MF shall not affect the current focus.How to choose and use white balance mode
White balance, simply put, is the image color temperature adjustment, for accurate color reproduction.
Unlike traditional photography, digital camera not through additional filter to achieve the white balance effect, it is only through the built-in program on the entire image color adjustment. General digital camera has several white balance modes to choose from, some digital cameras now have white balance value adjustment for photographers to provide more accurate white balance adjustment and a more spacious room for creativity.For night photography, if you do not use white balance adjustment, decorative buildings and scenery floodlights produce optical waveguides, rendered on the photosensitive element than the naked eye can see even more gorgeous shade (because the human eye can automatically correct color balance), and in the evening sky color temperature is shown on the sensitive components even more amazed at the beautiful colors.
If the automatic white balance adjustment, but lost the scenery beautiful colors, the image is black and white. Of course, the pursuit of the special effects of friends you can try a different white balance mode or numerical adjust white balance, colour control, the image will make you have unexpected results.How to select the image file size and format
