Vision Alterations: digital pinhole camera = very very cool

I was scared to make my digital camera into a pinhole camera because a lot of students were getting dust on their sensors. Another student said there was a simple device one could use to get it off (very simple device). But I don't own that device, so I was still very very careful. I read online to poke a hole in tinfoil because then it would be a super tiny hole whereas a super tiny hole in cardboard would be more difficult to create. However, I taped my cardboard with a needles-width hole in it to my camera and took a picture. At first it came out completely black, so did the next couple. I'd spent a long time package-taping this board to my camera, so I was determined to have a blurry picture! I pointed it at the ceiling light and voila! And image! And it was relatively in focus too, so I decided to not even add tin foil yet.
After that my pictures became less and less pinhole-y-type pictures (except they were still a bit out of focus). I took several pictures of myself because that was more interesting that pictures of pumpkins and old artwork to me. I had to shine a light very close to my face for the shoot because the lens is so tiny, not a lot of light passed through. I was amazed at how clear my pictures were until I removed the pinhole lens and replaced with my normal lens and took a picture of my nose. I was so amazed at the detail!

I covered the lens with torn up tin foil just to see if the shiny material would affect the way light enters the pinhole. It didn't really affect it the way I thought it would, but it did cover up a lot of the frame in a very interesting way. I took several images and when the exposure was longer, you could see the texture of hte tin foil, but when the exposure was shorter, the tin foil was just a black area. Both ways were interesting to me.
