This is related to photography because people use silver salts in camera films. However, Schulze didn't realize that he could've used the silver salts to make pictures.]]> 2022-12-10 02:21:26 UTC https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416164135 bui_kat000 https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416166419 Thomas Wedgewood created sun pictures. He did this by treating leather with silver salts and placing leaves on the leather. However, he couldn't figure out how to keep his "picture" from darkening and his leaf "pictures" turned black. For photography, they had to find a way to keep a permanent image, and combine light-sensitive material with the camera obscura.]]> 2022-12-10 02:28:48 UTC https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416166419 bui_kat000 https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416167814 Joseph Nicephore Niepce is responsible for the birth of photography. He coated a plate with an asphalt, bitumen, and placed it in a camera obscura. He left it there for 8 hours, which created the first photo. ]]> 2022-12-10 02:33:02 UTC https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416167814 bui_kat000 https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416169779 This is the first ever camera film, which was discovered by Niepce. Niepce told Louis Jacques Daguerre about his findings, and then Daguerre invented the Daguerrotype. This invention allows clear images to form. It puts a copper plate coated in silver Iodide behind the camera's projection, which is light sensitive.]]> 2022-12-10 02:38:35 UTC https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416169779 bui_kat000 https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416171186 The Daguerrotype was the first ever method of photography. In 1839 they created the first commercially made daguerrotype, and it was designed by Mr. Daguerro. It is a large invention, and it changed how the world took pictures!]]> 2022-12-10 02:43:40 UTC https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416171186 bui_kat000 https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416182671 The camera obscura was the first ever photo-capture device, and it was written about by the Chinese, but first explained by Aristotle. It helped artists with their drawings, and even made some of them look "Camera-like". There is a pinhole, and that pinhole is the only light source. The light is refracted off of the pinhole to create an upside down projection. This projection is then traced by the artist. This made it easier to make pictures, instead of having to do the portrait freehand.]]> 2022-12-10 03:22:42 UTC https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416182671 bui_kat000 https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416184062 The camera obscura was made portable. They did this by putting it in a box with the pinhole on one side and the other side, glass. This allowed artists to more easily trace their image by hand.]]> 2022-12-10 03:27:34 UTC https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416184062 bui_kat000 https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416194703 The word photography was used for the first time when the photographic process was made public. This invention was made by Sir John Herschel. Photographic process is how photographic film and paper are treated after photographic exposure. This is too produce an image, both positively and or negatively]]> 2022-12-10 04:04:43 UTC https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416194703 bui_kat000 https://padlet.com/bui_kat000/y0ly2s0cxcpf7d6s/wish/2416196384 Panchromatic Films are colored photographs. Everyone had tried to make colored photographs since the 1860s, but they weren't successful until 1906 when a film sensitive to colors was created.
