The history of Polaroid began in 1922 at the Mouven Summer Camp for Boys, which was located on a lake in Connecticut. Barney Griden worked as a mentor in the camp, he was passionate about physics and later patented eight inventions for scuba diving.
Barney demonstrated scientific experiments to teenagers, woke them in the middle of the night to show a thunderstorm and explain its nature. Seen experiments so influenced his students that in the future many of them took up science.
The most famous among those students was Edwin Land, he patented 535 inventions – only Thomas Edison received more patents. Land’s inventions include a polarizer, an X-ray film, 3D films, night vision devices for the army, and much more.

If you still have old films on which family events, important as memory, are recorded, it is quite simple to convert them to digital format: we will tell you how to digitize video tapes at home.
Why digitize a video?
The main reason for converting analog VHS video to digital formats may be the lack of a VCR to watch them periodically or problems connecting such a device to a modern TV. Interesting moments of life – birthdays, weddings, holidays, vacation trips – are still stored on film. And for viewing on a computer, media player or TV receiver with HDMI and USB connectors, the videos must be digital. Continue reading
