Why do all the photos of the sun taken by the camera have a black spot?

Remember never to bask in the sun with a digital camera again! After focusing, the lens will concentrate sunlight on ccd/CMOS, which will burn the ccd. If it is a DC\ or quasi-professional camera, it will affect the camera viewfinder even if you don't take pictures. If you shoot the sun by pressing the shutter, it will definitely affect ccd/cmos, unless you shoot light with low illumination and low color temperature, such as sunrise or sunset.

If you use a professional SLR camera, shooting the sun will burn the optic nerve, and shooting will also burn ccd/cmos.

Black spots appear in the sun photos taken by the camera because:

1. The camera automatically blocks the highlighted part after framing (the scene that the camera can't pick up mainly depends on the quality of ccd/cmos).

2.ccd/cmos's is not tolerant enough (that is, it can't perfectly show the transition from the brightest part to the darkest part of the picture), which is similar to the first one.

3. It can be ruled out that the ccd/cmos has been burnt out, because the burnt ccd/cmos will not display any images.

4. It can be ruled out that there are stained foreign bodies in the lens. The current lens manufacturing process is not as easy to dust as it was 20 years ago. When the lens is transferred from low temperature to high temperature, it is easy to generate water vapor in the lens group, so the general photographer will prepare a drying box.

5. It can be ruled out that the exposure is too strong, because when the exposure is strong, there will be no black spots on the screen, and usually the whole screen will turn white.
