The document discusses the history of photography. It describes how the first permanent photograph was created by Joseph Nicéphore Niépce in 1826 using a pewter plate covered in bitumen. This was followed by the first photo of people in 1838 or 1839, which showed two people in the bottom left corner as they were the only ones still long enough to appear in the 10+ minute exposure. The document provides context and examples of some of the earliest photographs.

1. Hello class today I am going to talk to you about photography.
History
First of we have the history of photography, The first permanent photograph was an
image produced in 1826by the French inventor Joseph Nicéphore Niépce. His
photographs were produced on a polished pewter plate covered with a petroleum
derivative called bitumen of Judea, which he then dissolved in white petroleum
Bitumen hardens with exposure to light.
Here we have the first image.

Next we have the first image of people in late 1838 or early 1839,was the first-ever
photograph of people. It is an image of a busy street, but because exposure time
was over ten minutes, the city traffic was moving too much to appear. The
exceptions are the two people in the bottom left corner, one who stood still getting
his boots polished by the other long enough to show up in the picture.
