I changed the camera to be shutter speed priority in order to capture my classmates jumping in different ways. The images change with different shutter speeds because a different amount of light is let in and the motion of the object you are trying to capture changes. You can create motion blur by having a low shutter speed and a moving objection front of a blank wall or non moving wall. A fast shutter speed allows you to make moving objects seem to be frozen in time. Shutter speed is best used when trying to capture a moving object in good focus or to create a motion blur to make an interesting image. An example of this would be, if your trying to capture a fast moving cyclist without capturing the background. Another example would be if your trying to capture a river flowing but make it look like its still.
SHUTTER SPEED NOTES: -Shutter Speed: Are both technical and aesthetic choice a photographer needs to make before releasing the shutter. -The Shutter inside your camera controls the duration of time the sensor is exposed to light. -Capturing blur or motion in your photograph can be emphasize movement and add drama. -A fast shutter speed is often utilized to freeze the movement of a subject. -A slower shutter speed can be used to show motion and visualize movement. -Shutter Speeds are expressed as seconds or fractions of seconds. -As a general rule to prevent unintentional camera shake you should avoid holding your digital cameras at shutter speeds slower than 1/ 2x focal lenght EX: when using a 200mm lens avoid using a shutter speed slower than 1/400 -Using a tripod can help eliminate camera shake when using slower shutter speeds. -The visual blur and suggestion of movement occurs because the subject is moving against a static background. -Layering motion of different subjects moving different directions at different speeds can set up interesting dynamics within a photograph. -Fast shutter speeds can make normal subjects appear to freeze in the air. -When photographing people running relatively close to the camera a shutter speed of 1/1000 second or faster should freeze most motion. -The distance the subject is from the camera, the speed of the subject, and the focal length of the lens will affect whether the subject is sharp or blurred. -Slower shutter speeds can help convey the idea of motion and movement. -Slow shutter speeds combined with panning can help isolate the subject from a busy and distracting background. (following the subject with the camera) -A tripod combined with a long exposure can capture the fireworks’ trails. (2 seconds @ f/6.3) -Water movement can be emphasized with long exposures.

For the cyanotype we started by creating a negative image on the computer using Photoshop CC. We then printed the images out. The painted over a thick paper with two different kinds of salt> Afterwards we placed our negative over the painted paper and placed it on a small box with a glass cover and took it out into the sun for 5 minutes. Finally we then dipped the paper in clean water until it was soaked. Afterwards we dipped the paper in water mixed with hydrogen pore oxide to get the dark blue color to the images. Finally let them air dry.
Minnie is driving down a lonely road. Enjoying the calm & beautiful scenery. Nothing different, just a relaxing drive to clear her mind. Minnie decides to stop at an open lot to go to the store real quick. Minnie comes to a stop when she spots Doc looking at her for too long when she's passing by looking for a parking spot. Minnie decides to park next to Doc. They both get out of their cars and start to walk towards each other. They begin talking about the cars and their preferences. They also start bragging about each others cars and the mods and dyno times they have put up. They don't quite like each other because of their car preference, "Muscle Car & Import Car". They decide to run their cars, they make plans to meet up along a long road that is often used for street racing. The conversation comes to an end abruptly. Each one gets into their car and they both leave the parking lot in different ways. Tires screeching and burning rubber smell all around, they both make an interesting exit. Doc brought a friend along to the race. His name is Juan, he's Doc's master mechanic. They lined up at the starting line. Engines revving, clutch held down tight, gears about to kick in, Juan waves his hands signaling to go! They're in the home stretch ! One looser and one winner! Out of the bloom a wild pony trots into the street. Getting in the way of both racers, they Slam on the breaks, yank the steering wheels...! Minnie lost control of her vehicle! She rolled her car and for her bad luck flew out of the car! She didn't have her seat straps on. Doc is paralyzed with fright, the pony crossed the street without even noticing! What happened next is all a blur for everyone...
Each different setting of aperture captured different depths of field. The f/1.8 captures a low depth of field which only focuses on the front box and everything else behind it is blurred out of the picture. The f/8 has a higher depth of field and in this image the focus point is bigger, so now the two front boxes are more in focus leaving the last box with a slight blur. Finally the f/16 has a very high depth of field and captures all three boxes in focus including the full background in focus.
NOTES: Shutter speed & aperture control the amount of light in a picture. Shutter speed controls moving objects. Aperture controls the amount of the image that is in focus. You have to manually control your camera using aperture. Use a tripod when using aperture. Shutter speed is much easier because we are used to using fractions. Aperture controls depth of field..

The concept of the camera obscura goes back to 1000 AD with Roger Bacon who first attempted this, as he called it pinhole camera. The concept of the camera obscure is simple. One must be in a completely dark room with the object trying to be captured right in front on the outside of the room and one small hole in the wall for the light to come in through. This allows for the person in the room to capture that image. The image will be upside down and in color if it is real bright outside. Different techniques were used afterwards such as adding a lens to get a sharper image, also a mirror to flip the image right side up. This is how the camera began to be, with the simple thought of capturing an image inside of a dark box.
