Define Camera Obscura. The natural optical phenomenon that occurs when an image of a scene at the other side of a screen (or for instance a wall) is projected through a small hole in that screen as a reversed and inverted image (left to right and upside down) on a surface opposite to the opening.
Explain the steps to create, expose and process a pinhole camera image: To create the pinhole camera we took Altoid containers, put in light sensitive paper, then using a needle we made a tiny hole in the front. To get the image we left the camera out for a week and the image was flipped upside down and horizontally. A small black piece of tape was used to cover the hole, allowing the paper to be exposed after making the camera sturdy.
How did you create a shutter and aperture on your pinhole camera body? The shutter and aperture were created by the size of the hole in the front and the distance we put the camera to the subject.
What was the focal length of the cameras? The focal length of the cameras were little holes made by a pin.
Where did you place your camera and what was your exposure time? My camera was placed on the fence diagonal from the tables outside and the exposure time was about a week.
What was the light source for the exposure? The light source for the exposure was the sun.
After taking down your camera and seeing the results, how did the image appear on the light sensitive paper? The image was very light on the paper with a dark line going across it.
Explain the steps you took to "process" your pinhole negative with the scanner and Photoshop. To scan my pinhole negative I typed in the correct settings and put the the negative in the upper left corner of the scanner. In Photoshop the image was flipped horizontally and vertically, inverted the colors, then put the image in black and white. Finally, what surprised you about your results? If you could re-do the process, what would you do differently to change your results? I was surprised by the random line going across the picture and if i had to redo the process i would put the pinhole camera closer what i wanted to take a picture of.

Where did you place the pinhole camera outside of school? I put the pinhole on a street cone in front of my house in my yard.
How many days did you leave the camera out? I left the camera out for a little over a week.
How did light, weather, location and time impact your results? The last day my pinhole was out there was a storm, causing many watermarks.
What changes (if any) did you make to modify your camera before taking the second image? I put the pinhole camera closer to the subject and made sure it wasn't going to fall.
Compare your out of school pinhole image to your first in school image: Both pinhole images have the sun in it, but in the out of school picture I have my house and trees.
What is similar and different about the images? Both images have weird marks (the line and the watermarks), but they both have the movement of the sun.
What is better or worse about the results of either image? The out of school pinhole image is worse because it has watermarks all over it.
