The above picture was taken with a minimalist, shirt-pocket device that Radio Shack used to sell for $80. You can read more about the camera and the image on my album page. It is fixed-focus and has no manual adjustments. Nevertheless, with proper lighting and a serious editing program, the results are quite pleasing.
Can we make digital photography even more economical? Yes, with an Aiptek PenCam Trio. Two years ago, I paid $13, and the price has dropped further since then. The smaller image, above, is what 0.35 megapixels can do, and I gave the picture a green frame to make it look like legitimate art. If you roam around the Web, you will find a lot of interesting imagery done with these simple cameras that are almost toys. My examples will be found in my Sampler Album.
