Introduction: Oat Container Camera Obscura

Picture of Oat Container Camera Obscura

The camera obscura is one of the oldest an most important concepts of photography. The concept of the camera obscura is that the light will follow a straight line as depicted in the image, because it follows this line it will result in what you're looking at being upside down and backwards. A larger hole will result in a brighter and easier to see image while a small hole will result a dimmer image but it will be more defined. That is enough about how it works so lets get into building it.

Step 1: Materials & Supplies

This is a very simple project and requires few supplies and materials and they are as follows.

Materials: Large 42 oz. Quaker oats container and clear gallon sized Ziploc bag.

Supplies: Scissors, sewing needle, or for a bigger hole a knitting needle.

Step 2: The Hole

On the bottom of the container simply find about the center and push through the pin.

Step 3: Looking Drum

Prepping The Bag: Cut just underneath the words on the bag leaving a large open pouch. Next cut along the sides of the bag so that you can open it up all of the way.

Fixing the bag: Stretch the bag over the top of the container and the tape it down while making sure that the bag stays tense.

Step 4: Testing

With only the pin you must go to a dark room to see the image well. Hold a light in front of the pin hole and an image of it will be projected on the plastic bag.

Step 5: A Larger Hole

As to produce a brighter picture I used a knitting needle to make my preexisting hole larger. In doing this it created a noticeably easy er to see picture and it can be used in brighter rooms.
