The way which you change the shutter speed is by turning the circular dial that has different symbols and letters on it so the arrow is pointing to the "S". This stands for shutter priority. The reasons you would want to use shutter priority is when taking a picture of something that is moving really fast so you speed up the shutter speed to capture that object mid-movement. Or if you would like to capture light trails in the dark, make the shutter speed longer to have a longer exposure of the moving object.

Daguerreotype: The daguerreotype was first thought of by Nicéphore Niépce and finished by Louis Daguerre in 1835. A photo is made using this process by shining a copper plate and reflecting the image onto the surface through the use of light. Then putting the plate into another camera tool and employing mercury vapor. Then another process is undergone to help prevent the picture from fading. The daguerreotype should avoid all light if possible or else it will fade. Cyanotype:
Created by Sir John herschel in 1842, cyanotypes have turned into what we know as blueprints today. In order to get these kinds of pictures. they have to go through a very tedious and chemical process. A paper is dressed in potassium ferricyanide and then items are placed onto the paper. Sunlight is then shone onto the paper and left to sit for a bit. Another chemical, ferric ammonium citrate, is added to the paper. After the photo is done being transferred to the paper, it is dunked into water. This turns the paper blue and VOILA! You have a cyanotype. It was Charmander’s first year in high school, and his older brother, Charmeleon, was nice enough to show him around the school. They were walking around school, casually eating their lunch and saying “Hello!” to friends. Charmander loved seeing the different kinds of people that went to the school. Whilst on the tour, they naturally made it to the football field where all the soccer players were practicing. The brother’s were looking around, minding their own business when, all of a sudden, the captain of the soccer team was slowly coming up behind them. His name was Xavier. He was known all around school as being a major bully and enjoyed putting others down for his amusement. Xavier was the best soccer player, which didn’t help with his already inflated ego. Xavier pushed the boys around, took their food, laughed, and called the boys weak. Other students just stood around and watched the beat down commence. The brothers were in such pain and couldn't get up. They moaned and groaned in agony. But, all of a sudden, a giant shadow fell over the three. There he was, Yorath, the captain of the football team. Everyone admired his strength and how nice he was to all people. Yorath was the person all guys dreamt of being. He stood before the three boys, looking deep into Xavier’s eyes. Immediately, Xavier shuttered with fear and tried to claim the brother’s started it. Before Xavier could say another word, Yorath threw his poke ball at Xavier and trapped him within the confined space. The brothers were surprised at the kind nature of such a strong person but they were very grateful he showed up when he did. Yorath made sure the brothers were okay and helped them to full recovery. Charmander and Charmeleon continued to thank Yorath for him helping them out. Yorath recognized that Charmander was just a freshman and Charmeleon was a sophomore and offered to help watch over them. With a sparkle in their eyes, the two brothers agreed to Yorath’s offer. From that day on, the three became very close friends and did almost everything together. Yorath did end up graduating before the two brothers but they were able to grow just as strong and pay forward what their friend had once done for them.
When taking these pictures, I noticed how the depth of field (DOF) had changed. Taking a picture with the f/1.8 aperture, the depth of field was extremely small. Only the first box on the right hand side was in focus while the other two were out of focus. The picture is also brighter since the lens was taking in more light. When using f/8 aperture, the middle box was mainly in focus while the other two still had a soft blur. This means the depth of field was larger than that of the f/1.8 aperture. Finally, the f/16 aperture made all three boxes come into focus and the borders and very far background of the picture were out of focus.
Aperture is the key to controlling the depth of field. When changing aperture, the smaller the f-stop, the more shallow the depth of field; but the larger the f-stop, the deeper the depth of field. On the camera when you use aperture priority, it allows you to change the aperture but automatically chooses a shutter speed.
HAVE CAMERA STRAP AROUND YOUR NECK AT ALL TIMES AND HOLD BY THE LENS AND HAND GRIP. In the beginning of photography, there was a thing called the "camera obscura". What this machine did was reflect an image upside down and print that image onto other materials in order to create an image. Many people thought it was heat that helped create the image, but it was actually light that had reflected the image onto various materials. This is what helped to create cameras and photography as a whole.
In order to make a camera obscura, there has to be a very dark room and it should be very sunny outside. Then a little hole with light is able to reflect the outdoors onto the room inside. I believe this led to the creation of photography because people were able to capture their favorite moments in life and reminisce on them later. Or even show their own perspective on nature and other everyday things people take for granted. |
