We changed the camera to be in shutter priority by turning the knob at the top to S and then using the dial to change the shutter speed. Depending on whether you are using a larger or smaller shutter speed, your image will come out blurry and bright or focused. A smaller shutter speed means the camera will take longer to take the photo and a larger shutter speed does the opposite. You want to use shutter speed priority when taking photos of something in motion. Shutter priority will help capture a clear image of the subject in motion.
Notes from class: -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 -capturing blur or motion in your photograph can emphasize movement and add drama -fast shutter speed is utilized to freeze the movement of a subject -slow shutter speed used to show motion and visualize movement -shutter speeds are expressed as seconds or fractions of seconds -to prevent unintentional camera shake you should avoid handholding your digital cameras at a shutter speed slower than ½ x focal length -using a tripod can eliminate camera shake when using slower shutter speeds -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 speed can make normal subjects appears 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 camera is from the subject, 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 -a tripod combined with a long exposure can capture the fireworks’ trails. 2 seconds at f/6.3 is good for fireworks -water movement can be emphasized with long exposures

Louis-Jacques-Mande Daguerre invented the daguerreotype in 1839. A Daguerreotype is the first ever commercially successful photograph process; each image is produced on a silvered copper plate. You must use silver, iodine, light, and UV to produce the photograph. Some equipment needed to make a Daguerreotype are a box for treatment with mercury vapor, a tripod, boxes for fuming with iodine and bromine, a soft buckskin pad used for buffing the plates, and some silvered copper plates. John Herschal invented the Cyanotype in 1842. Cyanotypes are made with Potassium Ferricyanide and Ferric Ammonium Citrate. To create a cyanotype, you start by brushing a thin layer of emulation ONLY on the top of the paper and wait for it to dry, next you arrange your artwork onto the paper and take it outside to sit in the sun for 6-12 minutes, after that you fix/rinse your paper in water until you get all the yellow out, and lastly you fix it by rinsing it in water with hydrogen peroxide.
Adventure Awaits One day a dog and bird were playing in the park just as they did every Sunday. Their day consisted of running around, playing catch, and making memories they will never forget. During one of their games of catch, the bird threw the ball a little too far. They both went searching for the ball, but instead came across something that looked like a map. The Journey Begins They made the decision to follow the map into the forest to see if maybe it would lead them to treasure. The journey was long and it took them several hours, but they continued walking in search of their prize. X Marks the Spot After several hours they finally reached the treasure and x marked the spot. They were both extremely excited to see that their long journey into the forest actually did pay off. Their treasure consisted of many coins which they were already planning on spending as soon as they got back to the park. The Great Escape Just as they began to collect their prize, they started hearing noises behind the bushes. All of a sudden an angry monster appeared who wanted his treasure back, but the animals refused to give it to him. The monster was now furious and began chasing the animals through the forest. The dog and bird finally emerged into the park and escaped the monster keeping the treasure and making an extreme memory they will never forget.
Aperture f/1.8, Shutter Speed 1/2,500th of a second, ISO 200 Aperture f/8, Shutter Speed 1/100th of a second, ISO 200 Aperture f/16, Shutter Speed 1/25th of a second, ISO 200 We used our DSLR cameras to learn and practice how aperture works by lining up 3 boxes in a diagonal line and taking photos to see how aperture changes how the picture looks. With an aperture of f/1.8, the photo is only focused on one of the boxes and the rest of the photo is blurred out. An aperture of f/8 focuses on all the boxes but the background is somewhat blurred. The aperture f/16 puts the entire photo in focus including the background. The larger the aperture, the larger the set focus will be and the smaller the aperture, the less it will focus on.
A DSLR camera stands for: Digital Single Lens Reflex. This type of camera uses mirrors to direct light from the lens to the viewfinder. Every camera we know today is designed like the human eye. Exposure is the amount of light collected by the sensor in the camera a during the picture. Having the shot exposed too long will wash out the photo and underexposing the shot will make the photo too dark, but almost al camera today have light meters which measure the light in the given shot and set an ideal exposure. The 3 primary controls this camera uses for exposure are aperture, shutter speed, and ISO. Aperture is a hole within a lens through which light travels into the camera body. It is expressed in F-#, also known as F-Stops. F-Stops are a way of describing the size of the aperture, or how open or closed the aperture is. A smaller F-Stop means a larger aperture,while a larger F-Stop means a smaller aperture. Small apertures increase the depth of field by bringing both the main subjects and the background into focus, while large apertures soften background details. Depth of field(DOF) is the distance to which object behind and in front of the focal point appear to be in focus. Shutter speed(exposure time), stands for the length of time a camera shutter is open to expose light into the camera sensor. If the shutter speed is fast, it can help freeze action completely. If the shutter speed is slow, it can create an effect called "motion blur." Shutter speeds are typically measured in fractions of a second. The slowest shutter speed for hand held photography is 1/60, anything lower should be on a tripod. ISO is the level of sensitivity of your camera to available light. The lower the ISO, the less sensitive it is to the light, and a higher ISO increases the sensitivity of your camera. The component within your camera that can change sensitivity is called, "image sensor" or "sensor." While shooting photos when it's bright and sunny you use 100 ISO, while it's cloudy you use 250 ISO, when you're indoors you use 500 ISO, and at night without flash you use 1600 ISO. The settings M on your camera stands for manual control over aperture and shutter speed, A stands for aperture priority, S means shutter priority, and p stands for camera sets shutter speed and aperture.
Camera obscura is the process of viewing an image in a very dark room through a hole in the wall or in the window which projects an image from outside onto the wall. The image projected will appear upside down and backwards and will be in color. In class we used camera obscura to view the outside of our classroom. The room was completely dark and we used a cardboard box to view the image from outside. It was very interesting to see the outline of all the trees and the whole quad.
