Lab #3 - Photopigments
Our next task is to work out how you translate the image formed in the back of a pinhole camera into some kind of signal that your nervous system can work with. We'll start addressing this question by examining photopigments in Lab #3. To complete this lab, you'll need access to some sunprint paper, which is available from a variety of different sources. Here's where I bought mine: http://www.sunprints.org.

When you're done, move on to the Lab #4 post to make a few more observations that will give us a little more information about the retina. Afterwards, we'll try to put all of this together into a more comprehensive description of what's happening at the back of the eye.
