Shelley, The dark areas are caused because that part of your paper lies outside the image cone as it projects through the pinhole into your camera. The diameter of the image circle expands outward from the pinhole at about 3.5" diameter per inch of focal length so if you can imagine the cone formed in your camera you will see why this effect occurs.

Subject: [pinhole-discussion] Image not filling out paper Okay... another newbie question. One of the cameras that I am using is an oversized oatmeal can. I'm using 8X10 paper, which fits perfectly when placed horizontally. The image isn't taking up the entire area, and I'm wondering what exactly causes this, and what I can do to get it closer to the edges. Here is an example of what I'm talking about: http://www.pbase.com/image/15725356 Shelley C. Rauch Acquisitions Dept.
