How to shoot a fantastic scene with a camera

Shooting refers to recording the mirror image that our eyes can't observe at ordinary times through long-term exposure. Use long exposure to record a process, not an instant.

slow photography has a wide range of subjects. It can make waterfalls flowing down into soft silks and satins; It can make surging waves into illusory clouds; It can make the traffic flow from point to line into a colorful picture. It can not only pull the blinking star into a big arc to show the remoteness and depth of the universe; You can also shoot light-colored animals such as geese and sheep into white clouds. These are pictures that we ordinary photographers can easily capture.

First, the camera must be stable

When shooting, a relatively stable tripod is necessary, and it is best to have a hand-held cable release. These are all to make the camera not shake when exposed for a long time, and to keep the shot picture clear after a long exposure.

If shooting in strong wind, the tripod should be as low as possible, and stones or sandbags should be hung under the tripod. The strap of the camera should also be fixed to the fuselage with transparent tape.

this is very important, because the strong wind will make the camera shake imperceptibly, and only this little shake will affect the image quality in long-term exposure.

2. Shooting by remote control

Whether it's a B door or a wonderful shutter, pressing the shutter by hand will cause slight vibration to the camera. The best way to avoid this problem is to use the remote control or cable release. If some cameras don't have cable release boots, they can also use the self-timer function instead.

Third, turn on the instant view function

Due to poor light or the use of a reducing mirror, autofocus is often not very real. Many mid-to high-end cameras have instant view function, so it is recommended to turn on the instant view function and zoom in for manual precise focusing. You can also focus first, and then add and subtract light sheets.

fourth, using the reflector pre-lift function

many mid-to high-end cameras have reflector pre-lift function. This is an effective way to reduce the slight vibration of the camera, which must be done.

V. Grasping the aperture and shutter

When shooting with a slow door, the problem of overexposure sometimes occurs even with a very small aperture because of its slow speed. Therefore, generally choose rainy days, dusk, early morning and other dark days to shoot, so as to control the exposure.

you need to remember: the aperture value of the lens for shooting the slow door should not be less than 22. Otherwise, sufficient exposure time cannot be guaranteed.

Generally, a camera can't measure the accurate exposure parameters by its own metering system in the dark, so there is no fixed rate and rules when shooting with B-door. Generally, the photographer chooses the exposure time by observing the scene environment and the intention to be expressed through years of accumulated experience, so the key is to look at the theme to be expressed and the expected effect.

Compared with the traditional film machine, the current digital camera is much more convenient for photographers. Inexperienced beginners make use of the characteristics of digital cameras several times, and after accumulating certain practice and experience, they will naturally get satisfactory results.

When shooting a still scene at night, use the B-gate or the T-gate, which can keep the moving effect of starlight or moonlight and make the whole picture vivid.

VI. Low sensitivity

Low sensitivity is also called ISO, and the lowest sensitivity of different cameras is different. Take Nikon D7 camera as an example, its minimum sensitivity is 2 (which can be extended to 1). In order to ensure enough exposure time, the first choice is to increase the sensitivity to 2 and extend it to L-1..

VII. Make full use of the reducing mirror

The reducing mirror is also called density mirror and grey mirror. It is a classification among many members of the color filter family. There are square and round shapes. There are light density, medium density and high density according to the dimming effect. Generally, the number ND2 is used as a light-density reducing mirror; ND4 is a medium density reducing mirror; ND8 is a high-density reducing mirror. Denser with higher density is seldom used. Adding ND2 filter can reduce the exposure of one grade, adding ND4 can reduce the exposure of two grades, and adding ND8 can reduce the exposure of four grades. If further dimming is needed, two or three reducers can be used at the same time. The polarizer can also be used as a light reducing mirror, but its light reducing effect is not as good as the former.
