How to cheaply shoot a solar eclipse

A very simple and cheap way to shoot a solar eclipse on a video and a photo camera.
The sun is very bright for shooting without special filters, but not all cameras, for example, smartphones can attach filters there are none or they are very expensive.
It's another matter of glasses for observing solar eclipses, they are cheap and they can be used with cameras and a smartphone to shoot solar eclipses, especially if they are partial and bright sun blinds the sensors.

This is the first time that I am photographing the Solar Partial Eclipse on August 11, 2018, which passes over the entire Arctic from northern Europe to eastern Russia.
