What should I pay attention to when taking pictures at night?

The general night scene, the background is usually very dark. Friends who know the principle of camera exposure know that dark background means that it takes a long time to fully expose the background and reveal the light and color of the background. This time may be110 second or longer. For the foreground model, because we use a flash, it actually takes only1100 seconds to complete the exposure. So if we shoot according to the flash synchronization method, we will see that the people in the foreground are fully exposed and clear, but the background is dark. Such characters appear abrupt and unnatural in the background.

No flash

To have a lens with a large enough aperture, generally speaking, at least f 1.8 is required to ensure a safe shutter and improve ISO 400-800. The brightness of ambient light should not be too low. Make full use of the large aperture and the light of street lamps to ensure people's exposure. And choose the background with light, and form a beautiful spot through the blur of large aperture. Such as street lamps, car lamps, large spotlights for buildings, etc. , is the best choice for natural environment light. When shooting with a large aperture, the surrounding light may be shaped like a balloon. If you shoot with a small aperture, the shape of light may shine like a star. At this time, you can choose the size of the aperture according to the shooting intention.

Increase ISO

When you meet the opportunity of street shooting at night, the camera settings are generally to turn up the aperture, absorb the light as much as possible, and turn the ISO to the highest. When it comes to setting the ISO value too high, photographers usually worry about "too much noise". Indeed, the improvement of ISO can improve the sensitivity, but it is replaced by the decrease of color contrast and inevitable noise.

Use a fixed-focus wide-angle lens

If you are serious about focusing on street shooting at night, I suggest you use a fixed-focus wide-angle lens. Usually, the fixed-focus lens provides a fairly large aperture, which can attract more light sources at night, such as from the largest 1.4, 1.8 to 2.8.
