I have seen some nice pinhole photography. Mostly are black and white. The pinhole lens is actually not a lens but only a hole. There is no glass, no coating, no focusing ...

I have owned several EOS cameras. When they were gone, they left me the camera cap.

I used the camera cap to make a pin hole lens.

Step 1: Materials

1. A camera cap.
2. A tin foil - 1"x1" is enough
3. Some tape
<p>I make one years ago for a film SLR.</p><p>I used thin brass put in a hole with a needle, sand off the burrs with very fine sand paper, the paint back side with flat black. I could see a faint image through the view finder. I probably had a larger hole. You could experiment with different size holes. The disadvantage of the aluminum foil is you have burrs around the edges which degrade the image. </p><p>Here is a link to a pdf file to make a pinhole exposure calculator</p><p>http://www.ilfordphoto.com/Webfiles/2011106152612113.pdf</p>
