Blow Out and Panning

For the blow out photo, I had an f stop of F8.0, and a shutter speed of 1/2, and an ISO of 50. Instead of having a low ISO, I think making the ISO a larger number would have done the same thing. Although bumping up the ISO and lowering the shutter speed would have created similar effects, it still came out the way it was supposed to.
When a photographer is trying to take a picture of a moving subject that he or she does not have control over, the photographer may use a technique called panning. Panning is where as the subject moves, the photographer moves the camera so that it continues to focus on the subject. A panning photo should look like the subject is clear, but the background is blurry. I think I did an OK job, but the legs on my partner start to get blurry. To take this photo, I had the aperture at F 8.0, shutter speed at 1/15 and ISO 50. I could have done a better job by probably picking a different location to take the photo, because it was difficult to get the lighting right in the quad area.

Shutter Speed



Shutter speed is how long the hole in the lens stays open for. This is measured in fractions. For example, if the shutter speed is at 1/100, it is going to take a picture at 1/100th of a second. The cameras that we used have a shutter speed that stays open for 15 seconds, which is how we got the pictures above. All the shutter speed does is let the light in in the amount of time that is set in the settings.
In the pictures above, the room was pitch black, save a little light coming in from windows and the light that the other groups were using. In order to get the pictures to turn out the way they did, we needed to change the ISO to a lower number, change the aperture so that we were all in focus, and set the shutter speed anywhere between 7 and 15 seconds.
I would change the settings between ISO, Aperture and Shutter Speed depending on the situation. If I wanted to zoom in on something to show depth of field, I would have to change the Aperture setting. If I wanted to catch a lot of light, but in a short amount of time because I don't have control of the subject, then I would increase the ISO and leave everything else the same. If I wanted to capture movement, or just experiment with light, then I would leave the shutter speed on for a longer amount of time.
My favorite picture is the one where we have our heads in two different positions. Even though it wasn't any one of our ideas, it was still a really cool idea, which made the experience a lot more enjoyable.

Aperture


The aperture is how big the diameter of the hole in the lens is, which allows for the depth of field to change. For example, in the first picture, there is no depth of field, which means that the lens is long, and the background is blurry. In order to attain such photo, the f-stop (how aperture is measured) has to be a relatively small number, so that the hole opens up bigger so that it'll allow more light in to focus on the main subject. In the second picture, the photographer used a larger f-stop, which makes the hole in the camera smaller.

ISO

ISO Flash

ISO 50
ISO 400
ISO 5000
ISO refers to the film speed of the camera, which is how sensitive the film or pixels are to the light that enters the camera, or how fast the light comes in. Imagine a ray of light, like a conveyor belt, that enters through the lens of the camera. . Different speeds of the conveyor belt, or light, have different results. Thus, if the light of the conveyor belt runs really slow, as in ISO 50, then there is going to be less light that enters the camera. If the light on the conveyor belt runs really fast, as in ISO 5000, then there will be a plethora of light entering the camera.
When I used flash in my photos, I realized that even though it added light into the picture, it also took away the natural light of the Christmas lights in the background. That is why as the photos progress from dark to low, the intensity of the Christmas lights increases. However, at high ISO speeds, it is important to make sure that the camera does not move and that the subject does not move because there is a chance that the picture will turn out blurry.

Flash

In this photo, the lack of flash helps the brilliant colors appear and seem more intense when compared to the darkness surrounding it. Although using flash freezes time and eliminates blur, while also getting rid of shadows and adding lighting to situations, it can also create unfavorable lighting situations and could also disturb the subject of the picture. If one is out in the sun, but the shadows of the sun creates shadows on the person who is getting their picture taken, then fill in flash would be a good idea to use because the flash will add in the light that is taken up by the shadow. Flash would not be a good idea when one is going to take a picture where they want to capture the colors because when one uses flash, it has a way of taking away the original color from the picture.

Metering

The light meter measures the amount of light that enters the camera. Light meters also try to measure for the middle gray. In the first picture, there is not much light. That is because I focused in on the monitor, which made the light show everything else that was nearly as intense or bright as the computer screen. In the second picture, I metered in on Jess's face. This allowed for a wider spectrum of light to enter the camera because It is trying to show the light that matches close to Jess's skin. Spot metering can help me in the future by helping me get the lighting right in a picture that may have been too dark otherwise.

Surrealism: In the Land of Butterflies

In this dream, there are many things that are taking place in far as the symbolism behind the components of the piece. First is the butterfly. The butterfly could be one of many things ranging from someone who can't settle down, to one who feels like they can soar through the sky. This dream is a combination of both. This person feels like they can do anything they want, but does not know exactly what to do. That could also be why the background of the room is space. The blooming butterfly flowers could be interpreted as growing or beauty. Or because the flowers are made out of butterflies, in contrast to the previous statement about the butterfly, the stems could represent the path, and the different flower could represent the different outcome. However, the freedom represented by the butterflies is contrasted with the box effect that is created. This could mean that the person feels like they are trapped or are being boxed in by someone or something. The eyes in the back wall give the effect that there is someone watching her, and that the decisions she makes will not only be known by her, but others will know too. There is also a miniature version of the person on top of the flower step, which could be representative of how we are really small compared to the rest of the world.
