How to use the shutter of digital camera

The shutter of a digital camera has two gears.

Half-press is to operate the camera to start autofocus and photometry, so as to make automatic preparation for taking clear photos. It's the red light you said (in fact, it's automatic metering, and in fact, the lens has begun to focus automatically ...)

At this point, the camera did not start the actual shooting action, but made all necessary preparations for the final shooting.

Press all, press half, and wait a moment. When the camera is ready, a green box will appear on the LCD screen, indicating that the camera is ready to take pictures. Then at this time, if you keep pressing the shutter, you will take pictures and take pictures at the semi-timely setting.

Tip:

If you press the shutter directly, the camera will not be able to complete autofocus metering in time, and the captured image will not be able to get a clear photo.

If the half-press focus metering is not completed or not fully pressed after the end, release it directly, and the camera will automatically release the previous preparation state to prepare for the next photo. The next photo still needs to be prepared by semi-pressing autofocus metering.

The correct method: first aim at the scene to keep the camera still, and then hold it for a long time to make the camera ready for focusing and metering. The red prompt box on the screen turns into a green box, indicating that the preparation work is completed, and then you can continue to press the shutter to the bottom instantly to take pictures. In this way, you can get clear and satisfactory photos.
