Chemical photography
For centuries images have been projected onto surfaces. The camera obscura and the camera lucida were used by artists to trace scenes as early as the 16th century. These early cameras did not fix an image in time; they only projected what passed through an opening in the wall of a darkened room onto a surface. In effect, the entire room was turned into a large pinhole camera. Indeed, the phrase camera obscura literally means "darkened room," and it is after these darkened rooms that all modern cameras have been named.
The first photograph is considered to be an image produced in 1826 by the French inventor Nicéphore Niépce on a polished pewter plate covered with a petroleum derivative called bitumen of Judea. It was produced with a camera, and required an eight hour exposure in bright sunshine. However this process turned out to be a dead end and Niépce began experimenting with silver compounds based on a Johann Heinrich Schultz discovery in 1724 that a silver and chalk mixture darkens when exposed to light.
Niépce, in Chalon-sur-Saône, and the artist Louis Daguerre, in Paris, refined the existing silver process in a partnership. In 1833 Niépce died of a stroke, leaving his notes to Daguerre. While he had no scientific background, Daguerre made two pivotal contributions to the process. He discovered that by exposing the silver first to iodine vapour, before exposure to light, and then to mercury fumes after the photograph was taken, a latent image could be formed and made visible. By then bathing the plate in a salt bath the image could be fixed. In 1839 Daguerre announced that he had invented a process using silver on a copper plate called the Daguerreotype. A similar process is still used today for Polaroids. The French government bought the patent and immediately made it public domain.
Across the English Channel, William Fox Talbot had earlier discovered another means to fix a silver process image but had kept it secret. After reading about Daguerre's invention Talbot refined his process, so that it might be fast enough to take photographs of people as Daguerre had done and by 1840 he had invented the calotype process. He coated paper sheets with silver chloride to create an intermediate negative image. Unlike a daguerreotype a calotype negative could be used to reproduce positive prints, like most chemical films do today. Talbot patented this process which greatly limited its adoption. He spent the rest of his life in lawsuits defending the patent until he gave up on photography altogether. But later this process was refined by George Eastman and is today the basic technology used by chemical film cameras. Hippolyte Bayard also developed a method of photography but delayed announcing it, and so was not recognized as its inventor.

In 1851 Frederick Scott Archer invented the collodion process. It was the process used by Lewis Carroll.
Slovene Janez Puhar invented the technical procedure for making photographs on glass in 1841. The invention was recognized on July 17th 1852 in Paris by the Académie Nationale Agricole, Manufacturière et Commerciale.

I'm not a professional, but is there a local art school or college you can go to? High schools might offer it for free. Contact a HS or a college and speak with a teacher. They can give you some advice. You shouldn't have to pay that much if at all to learn about photography at your age. Do a google search in your area and see what comes up.

1839,- with the Daguerrotype; this was the first public notice of the invention, so that was the year.
However the calotype was known before that (1837) but was not published; when Fox Talbot new about it he took the necesary steps to make his invention known.
my comments are not copy and paste
