Some amazing "amateur" photography of the Anterior Median and Anterior Lateral Eyes of an adult female Phidippus putnami. I.e. a jumping spider. The photographer is Thomas Shahan who is interviewed here. His Flickrstream is here. Money quote:
After experimenting around with various ways of taking high magnification macros, I realized that nothing man-made is really all that exciting up close. I realized pretty quickly that bugs were one of the only things worth the effort. Nothing compares to the complexity, color, and intricate detail of arthropods up-close. Also, there is a seemingly infinite number of subjects when it comes to bugs.
