How to adjust the exposure of Apple photography

1. First find the camera APP on your mobile phone, and then open it to enter the camera.

Then, there is a lightning icon in the upper left corner. Just select the lightning icon in the upper left corner.

3. Click the lightning icon directly, and the exposure function of the camera will be turned on.

Extended data:

Exposure is a combination of aperture, shutter and sensitivity ISO:

Among them, aperture and speed jointly determine the amount of light entering, and ISO determines the photosensitive speed of ISOCCD/CMOS. If the light input is not enough, we can open the aperture or slow down the shutter speed, and if not, we can increase the sensitivity (ISO). The disadvantage of large aperture is that the resolution is not as good as that of middle aperture. If the shutter speed is reduced, the picture may be pasted, and the quality of the picture will also decrease after the ISO is improved. Without a perfect plan, how to choose should be flexible.

The aperture (numerical value) is actually how big the small round window is, and the shutter (speed) is how long the window has been open. Assuming that the window is only open for 1/4 4 seconds, it is obvious that if the window is half open for 2 seconds, the film can be exposed correctly, because1/4 * 4 =1/2 * 2 =1,and the light input is the same.

Similarly, if the window is fully open, the exposure time only needs 1 second. If the aperture of a lens is F4, and in photographic terms, the shutter speed of F4 is 1 sec, which is the correct exposure value, then F5.6 and 2 seconds, F8 and 4 seconds can also get accurate exposure pictures.
