Is it harmful for the matrix of the camera (or the camera in the phone) to photograph the sun?

Question

Cameras

Online answers vary greatly.
And the second question. Camera cameras on phones are always open, or are they closed by some kind of curtain in standby mode?

Answer 1

Very bad. Have you ever burnt inscriptions with a magnifying glass on pieces of wood?
This is the same burning out, but on the matrix.

Answer 2

Learn to read instructions (manuals) for devices. And there will be no such questions.

Answer 3

There are two negative factors here: infrared radiation (that is, heat) and ultraviolet ...
CMOS technology (which makes the vast majority of matrices) can withstand significant heat. But everything has its limit. The optics of the camera focuses the image on the entire area of ​​​​the matrix. Thermal radiation is partly absorbed by the optics, and partly goes to the matrix. Accordingly, the smaller the matrix (and the cheaper the device), the easier it is to overheat / kill the matrix. Plus, the increased temperature of the matrix causes increased noise and the quality of the images is very much reduced ...
Ultraviolet causes degradation of the optics. For DSLRs, the issue is solved with a UV filter. Expensive soap dishes have an appropriate optics coating. Cheap soap dishes have no protection. Respectively…
One piece of advice - in the sun, always cover the lens with a shutter or a standard cover. Use lens hoods so that direct sunlight does not fall on the optics. And do not shoot in front of the sun. Almost always, the angle can be moved by 10-15 degrees.

Answer 4

You can shoot, but be careful. With prolonged exposure, the matrix may well overheat, especially with a telephoto lens. Also, when using a DSLR, it is strongly not recommended to look at the sun through the viewfinder. In general, if you don’t plan to shoot the sun every day at a long focus, then you don’t have to worry much.

Answer 5

I wrote a long comment about a short shutter speed when shooting the Sun, and then I noticed the key phrase “on phones”. On phones, as far as I know, as well as on webcams, there are no curtains, the matrix always looks outward. However, the size of the lens on phones is so small that I don't think it's worth worrying too much about it. But shooting the Sun for hours is also not worth it - there is a limit to everything, in the Sun even dye proteins in the hair burn out, to say nothing of high-tech matrices.

Answer 6

It is strange that no one mentioned solar filters, such as AstroSolar film, which copes well with both radiations.

Answer 7

The question may be off topic, but I have no idea where to ask. Can someone explain what happened to this photo and why it happened? as I understand it, the light was reflected from the reflective sticker and beat the photo. will there be any consequences for the matrix of the phone?
