What is a solar observation card? How to shoot a total solar eclipse with a camera?

Sun observation card is a kind of dark card, which is used to protect eyes when observing the sun, similar to sun observation glasses.

The Budd film mentioned upstairs is a professional filter for shooting the sun, but it is hard to buy in the market. When shooting the sun, you need to use a depth filter or a medium with low light transmittance as a protection for the camera. If you use a small digital camera, it is more difficult to shoot. If your camera has a manual function, first put the aforementioned filter media in front of the lens, and then use the following shooting settings:

Prominence, ISO- 100, F/8,11000-1/500 second shutter speed.

Corona, ISO-200, F/8,1100-1/32 seconds shutter speed.

External corona, ISO-400, f/8, 1/8- 1/4 seconds shutter speed.
