What does it mean to take pictures with a large aperture?

It was shot with a large aperture lens.

In this way, the camera photosensitive device can get more light, so as to take brighter and clearer photos. Large aperture photography technology is very common in photography and is widely used in portrait, landscape and night scene photography. In photography, the aperture is an important parameter of the camera, and it is a component used to adjust the amount of light entering the camera lens.

A lens with a large aperture allows the camera's photosensitive device to get more light, thus making the photos taken brighter and clearer. When shooting portraits, a large aperture can blur the background, highlight the characters and make them stand out.

When shooting a night scene, a large aperture can increase the amount of light and make the photo brighter. When shooting scenery, a large aperture can make the whole picture clearer and more detailed.

Features of large aperture photography:

1, reduce lighting requirements

This advantage is self-evident. If the aperture is large, it means that the inlet aperture of the faucet is large and the inlet area will be enlarged. For example, if the aperture is expanded from F5.6 to F4, the water intake area will be doubled; The aperture will be expanded from F4 to F2.8, and the water intake area will be doubled. And so on.

2, improve the exposure speed

Aperture, speed and sensitivity are mutually restricted and interrelated, which embodies the mutual assistance and complementary relationship of "changing one for another". If the aperture is increased under the same conditions, the exposure time can be reduced, that is to say, the shooting can be completed at a faster speed, and the picture can be prevented from being burned because of the slow speed.

3. Improve the image quality

Similar to the "second" analysis above, because the aperture increases and the amount of light enters increases, it is not necessary to blindly complete shooting by improving the sensitivity, so relatively good image quality can be obtained.
