This shutter speed exercise took place outside of our classroom. We were told to take photos using Shutter priority. We changed apertures (1/3, 1/30, 1/60th, 1/250 and 1/1000) and took photos of our partners jumping, while focusing on one person who wasn't jumping. As for the changes in photos, there were many. It is to be noticed that at 1/30th of a second, movement is still being expressed in the photos; however, at 1/1000th of a second, everything is almost completely still. With a fast shutter speed, it would be possible to photograph action, such as sports or cars, nature, such as birds or fast animals, and much more.

DaguerreotypeThe Daguerreotype was the invention of Louis Daguerre and Nicephore Niepce. It was announced in 1839 after years of experimentation by the two men. Mercury, iodine, and silver are used. These photos could allow someone to know what their grandparents looked like, even if they hadn't met them. A Daguerreotype was a positive and negative image at the same time using camera obscura. They are permanently processed on silver-coated copper plates, usually protected by a layer of glass. These photographs are surprisingly very detailed, despite their old nature. CyanotypeScientist and astronomer Sir John Herschel was the inventor of the Cyanotype. It was invented in 1842, following the invention of the Daguerreotype. The chemicals used in a cyanotype were potassium ferrocyanide and ferric ammonium citrate. It was based from salts that presented a blue and white photograph. Sometimes, it can be referred to as a blueprint.
To create a cyanotype, we followed multiple steps provided by our teacher. Firstly, we were handed paper with emulsion painted thinly onto one side. Then, the drying process took place, which consisted of multiple hairdryers and air drying the emulsion. We then chose what we wanted, and arranged our artwork. The above photos were my choices. We laid the transparent photo on top; some people chose flowers, stencils, and other available materials to layer in order to create their cyanotype. Then, we laid our ensembles onto a board where we placed a piece of plastic on top of them. We were then instructed to leave the boards out for 6 to 12 minutes. After our time, we brought them inside and rinsed them in water until the paper was no longer yellow, and it was a vibrant blue color. Following that step, we then moved to the last station, and rinsed our cyanotypes with hydrogen peroxide. Finally, we were able to dry our pieces; my finished products are the above photos. Donnie the Dumb Dinosaur was enjoying his day off, relaxing with his friends, when he sees his arch nemesis, Leonardo the Lion and his friends approaching his side of town. The rivalry between the dinosaurs and the safari animals has been ongoing for years. It dates back to their ancestors. Filled with anger and rage, Donnie turns to his friends. Barney and Jonathan are his fellow, smaller friends. He tells them, "We need to build a wall in order to keep them out of our side of town." Then, all three dinos exclaim in unison, "Yeah!" Donnie, Barney, and Jonathan get to work on their wall. They decide to build starting at the root of the town center, Peace tree, which is ironic. They begin collecting materials eventually getting a decent amount of material to begin a sufficient wall to keep their enemies out. After about 5 long minutes, they get this far. Leonardo the Lion, Zeke the Zebra, Chilly the Cheetah, Gerald the Giraffe, and Ricky the Rhino laugh in unison. They sit back and have a snack, enjoying each others' company. They admire the dumb dinosaurs' attempt to keep them out. They continue cracking heaps of jokes about how dumb the dinosaurs are. The safari animals keep laughing at the dumb dinosaurs. They are laughing because the dumb dinosaurs, in their attempt to keep trespassers out, are keeping themselves locked in. Now, all they have is their small space at the root of Peace Tree, with little food and little water.
In this photo, I noticed that the focus was solely on the first box. Everything else was blurred and out of focus, bringing the viewers main attention to the first box. The smaller the number, the more focused on one subject the photo will be. In this photo, I noticed that the focus is softened, releasing the frontal focus on the first box; however, the main subject is still the box in the front. In this photo, there is no specific focus, whereas in the other photos, there is a specific focus. I noticed that the smaller the aperture is, the more emphasized a certain subject will be. The bigger the aperture number is, the bigger the depth of field is; one would be able to focus on and capture more.
Aperture Notes To guide a viewers eye, one would use the depth of field. So, if the wide aperture is focused on an object, such as the box, the viewer will pay most attention to that subject. What does DSLR stand for?

Camera obscura in Latin translates to "dark room." It is an optical phenomenon that occurs in a completely dark room with a small source of light to project an outside image. The image is inverted backwards and upside down, creating a complex illusion. Camera obscura was one of the first forms of photography, and it was extremely important in the development and advancement of photography.
