Welcome to my DP
My first high school exhibition
My high school exhibition was alright it was really hot and boring and wasn't much to look and talk about.
What was required for this project was to make a pinhole and to take pictures. I also had to decorate it for exhibition. For my pinhole cameras to work i had to wrap it in tape so it would let sunlight inside and screw up the photo paper.
my pinhole - negative
my pinhole - negative

What You Didn’t Know About Light
Light is an electromagnetic wave, because it has accelerating, moving charges which create the electromagnetic field, causing it to be electromagnetic. These fields travel at the speed of light. Light, has a frequency and can interfere with itself. These are both characteristics of a wave. We can represent light with rays and ray diagrams because the rays represent the paths of light waves and how they change when going through something. This helps explain the path of light, why it takes that path, and the reflection and refraction. Specifically because, you can then show a line that is going straight and then suddenly switches angles, so by looking at the image, you can tell that it was altered in some way such as an aberration. It helps you to visualize everything that is being done to the wave. This ends up being a ray diagram. The light being portrayed in a ray diagram is moving at the speed of light, which is amazingly fast. The speed of light is 3x10 te 8th power meters per second. This is equal to 300,000,000 meters per second. OPTIMAL DISTANCE CALCULATIOIN All of these waves that are around us, are compared as the electromagnetic spectrum. It is from radio waves to gamma rays and everything in between. Radio waves have a low frequency, and a long wavelength. While gamma rays have high frequency and a short wavelength. Visible light is a very small part of this spectrum, and it is balanced right in the middle. Of all of the waves around us, we can only see a small percentage of them. We see these as colors, violet is on the higher frequency side, and red is on the longer wavelength side. The combination of frequency and wavelength decide what color you see.
The Physics of a Pinhole Camera Light rays come around all sides of the object in the photograph into the pinhole, and onto the photo paper. Because of this the photo paper gets exposed in the space around the image giving you a negative image of your picture. The image is condensed and smaller because it has to go through the tiny pinhole which cuts out the wide rays of light. The photo is upside down because the light rays go straight around the object with nothing to reflect or refract the light, so when they go through the pinhole at an angle they continue going at that angle thus flipping it. A smaller pinhole means sharper image because of less light so, it is not as fuzzy. Without a lot of extra unnecessary light, you only get the image that you want. The pinhole on a pinhole camera acts as a lens because it only allows certain light to get in and after going through such a small hole, the light is condensed and can’t spread out very much in the distance to the photo paper. This results in having a smaller, and very crisp image.
The Physics Behind a Camera
A digital camera can capture a photograph, because it has a sheet of semiconductor material, instead of photo paper. The light rays, hit this material, and the photons displace the electrons from it. There is an electrical charge at the site of where the light hit the material. This defines the image. On top of this sheet, there is a sheet that filters colors, for every group of two by two pixels, one pixel is blue,another is red, and two pixels that are diagonally opposite from each other are green.Two green pixels are placed there because the human eye has evolved to be much more sensitive to green, so more is needed. Depending on how the light goes through these sheets, the camera determines the approximate color, and overlays it on the image. This is an amazing part of the technology inside a camera. Many cameras use multiple lenses, they do this because having more than one lens can help prevent distortions called aberrations. An aberration happens when a single point of an image doesn’t translate back to a single point after going through the lens. When this occurs; your picture can be blurred, magnified in some areas, distorted, have uneven brightness, and other bad effects. Light can travel through the lens because glass is transparent to light rays, and so light doesn’t get affected when passing through. If nothing is stopping the light from going somewhere, the light will just go right in. The advantage of using a camera with a lens compared to a pinhole camera is that lenses can help stop aberrations, and especially if you have multiple lenses, which most cameras these days have. Also, a modern camera is much more efficient and easy to use because you don’t have to use photo paper and a lot of chemicals, you just use a microchip, and some color filter sheets. For the user of a camera, is is as easy as point and shoot, which is why they are much more accessible these days to the average person.
The Camera and The Human Eye
The camera is a man made version of the eye. The human eye has a pupil that controls how much light enters. On a camera there is a shutter to do the same thing. The eye’s lens accommodates for lack of focus amazingly quickly by changing the shape of the lens, it uses the ciliary muscle to do this. In contrast, a camera adjusts the distance between the lens and the film by moving the lens to control the focus. Both the camera and the eye sense an image. The eye uses the retina which displays the image upside down. The rods, cones, and the rest of the image reading system read the image sending it to the brain. A camera uses film or photo paper, which is light sensitive, to sense and form the image. For the eye, light is refracted first by the liquid, on top of your eyes lens, then by the lens, followed by the vitreous humor which is the jelly substance between the lens and the retina. A camera will simply use one o more lenses to create the same effect. Both a camera and human eye do almost the same things to capture images, but just slightly tweaked, and with different materials.
