Camera Obscura
Our assignment was to build a camera obscura. I used a Pringles can, grocery bag, tap, and tinfoil to make my camera. The first step was to cut the Pringles can 2 inches from the bottom. Next, I taped the grocery bag to the longer half of the can. I then taped tinfoil around the tap that conjoined the two parts back together. The foil was used to keep the light out of the tube. Lastly I pocked a hole on the bottom of the tube (metal side) with a thumbtack. The hole will allow light to enter the tub creating on image on the grocery bag.
Camera Obscura Tutorial
The group camera obscura, the camera we build was designed to be able to focus on certain objects. In order to achieve this, we first made the pinhole bigger to allow more light to enter and then we added a lens to the hole. The lens allowed the image to appear more focused. The screen inside the camera can me moved forward or backwards depending on the distance between you and the object you are viewing to make the image focus better.
