Question

Why do you think photography was invented in 1839 when the necessary technology had been available long before that date? response should be between 200-300 words and include information from the textbook as well as your own ideas independent of the text. Please feel free to include photographs.

Answer 1

The history of photography began in remote relic with the disclosure of two basic principles: camera obscura image projection and the perception that a few substances are unmistakably modified by introduction to light. There are no ancient rarities or portrayals that show any endeavor to catch images with light delicate materials preceding the eighteenth century. Around 1717 Johann Heinrich Schulzecaptured cut-out letters on a container of a light-delicate slurry, yet he clearly never thought of making the outcomes sturdy. Around 1800 Thomas Wedgwood made the first dependably recorded, albeit ineffective endeavor at catching camera images in changeless structure. His examinations produced detailed photograms, however Wedgwood and his associate Humphry Davy found no real way to fix these images.
In the mid-1820s, Nicéphore Niépce first figured out how to fix an image that was caught with a camera, yet in any event eight hours or even a few days of introduction in the camera were required and the soonest results were extremely unrefined. Niépce's associate Louis Daguerrewent on to create the daguerreotypeprocess, the first openly reported and commercially practical photographic procedure. The daguerreotype required just minutes of presentation in the camera, and delivered clear, finely nitty gritty outcomes. The subtleties were acquainted as a blessing with the world in 1839, a date commonly acknowledged as the birth year of reasonable photography. The metal-based daguerreotype process before long had some challenge from the paper-based calotypenegative and salt print processes developed by William Henry Fox Talbot. Ensuing advancements made photography simpler and progressively flexible. New materials decreased the required camera presentation time from minutes to seconds, and in the end to a little part of a second; new photographic media were increasingly affordable, touchy or advantageous, including roll films for easygoing use by novices. In the mid-twentieth century, advancements made it workable for novices to take pictures in natural color as well as in black-and-white.
The commercial introduction of PC based electronic digital cameras during the 1990s before long reformed photography. During the main decade of the 21st century, conventional film-based photochemical techniques were progressively underestimated as the useful points of interest of the new innovation turned out to be generally valued and the image nature of respectably evaluated digital cameras was ceaselessly improved. Particularly since cameras turned into a standard component on cell phones, taking pictures (and right away distributing them on the web) has turned into a pervasive ordinary practice far and wide.
