How to adjust the night scene mode of Canon g7x?

Night scene mode is an important mode for camera shooting.

Any camera should follow the same pattern when shooting night scenes.

Canon G7x is a non-replaceable lens camera.

Therefore, this camera should also follow the law of photography when shooting night scenes.

Specifically, shooting night scenes has the following points:

1, low-sensitivity shooting.

Night scene shooting, the light is very dark, you need to shoot slowly. If the iso is too high, it is prone to noise.

Therefore, you must use a low sense when shooting night scenes. The lower the sensitivity, the better. ...

2, small aperture shooting.

In fact, a large aperture can also shoot night scenes.

However, lighting is a very important light source in night scene shooting. In order to show the effect of outstanding star gathering, night scenes are usually shot by narrowing the aperture ... Generally, F 1 1-F 16 is used, and in extreme cases, F22 is also used ... But the imaging effect will be reduced because of aperture diffraction.

3, slow door shooting.

This is actually very easy to understand. If the sensitivity is low and the aperture is small, the amount of light entering and the sensitivity to light will be reduced ... If you don't shoot slowly, you will be underexposed ... Plus the ambient light is dark when shooting at night, you must shoot with a slow door.

In addition, one thing needs to be explained: night shooting has a special state ... that is: shooting in the starry sky.

Starry sky, darker light. So you can't shoot the starry sky with a small aperture, but with a large aperture ... you must also use a large aperture lens to shoot such a theme. Only in this way can we ensure enough light.

In addition, because the starry sky is too dark, it is not enough to simply slow the door with a large aperture. It is necessary to use high sensitivity blessing ... generally, it is necessary to shoot with iso3200 or higher sensitivity.
