Welcome
After organizing galleries from my existing images, I need a blog to track my ongoing observations, work in progress, and references. Here have the freedom to use multiple images in an entry and link to related material anywhere.
Most blog images will link to full resolution, Creative Commons licensed, images for download, just as with the gallery images.
