I experimented with a couple of different approuches, but ultimately I hit upon taking the photos with my Sony Cybershot DSC-L1 digital camera on "auto" mode with multi-point focus enabled and the flash turned off. The baseline photos this created were not spectacular, but using Adobe Photoshop Element 3's "Auto Smart Fix" enhancement at 25-50% effectiveness I was able to improve the brightness and contrast of the photos without making them look bland and washed out. I'm pleased with the result -- the shots aren't spectacular, but they nicely illustrate the tree.
