Levitsky, which required the exposure of 15 seconds.

The basis of a digital camera was invented in 1973. It was a
charge-coupled device, with which it was possible to obtain an image size of
100×100 pixels. The first astronomical electronic photo was taken with the help of this device the following year.

The story of a digital photo begins with camera Mavica,produced by the company Sony in 1981. Mavica is almost a full SLR with interchangeable lenses and resolution of 570h490 pixels. But then it was considered a “static camera,” the result of which was not the videobut static images – shots.

Papilio machaon   the Old World swallowtail, is a butterfly of the family Papilionidae. The butterfly is also known as the common yellow swallowtail or simply the swallowtail (a common name applied to all members of the family, but this species was the first to be given the name). It is the type species of the genus Papilio.

               This butterfly is present throughout the entire Palearctic region, ranging from Russia to China and Japan, (including the Himalayas and Taiwan), and across into Alaska, Canada, and the United States, and thus, is not restricted to the Old World, despite the common name.

              In Asia, it is reported as far south as Saudi Arabia, Oman, the high mountains of Yemen, Lebanon, Iran and Israel. In southern Asia, it occurs in Pakistan and Kashmir, northern India (Sikkim, to Assam, and  Arunachal  Pradesh), Nepal, Bhutan, and northern Myanmar.The butterfly has a strong and fast flight, but frequently pauses to hover over flowering herbs and sip nectar. It frequents alpine meadows and hillsides, and males are fond of 'hilltopping', congregating near summits to compete for passing females. At lower elevations, it can be seen visiting gardens.
