Love the autochromes, been obsessed with them actually since I first learned of them in Popular Photography magazine WAAAAAY back in my college years. There aren't any images I can find easily with a "Creative Commons" license, but can share this link to the gallery of images at the American Photography Museum of Photography's show from a few years back. Maybe that will help inspire others to understand the passion I have for those old images.
In looking back at the collection in that gallery one thing that jumps out is the saturation level of colors varied quite dramatically. Some lost all blues, others had them very saturated. Gives me leeway in my exploration of the process in CS5.
As discussed the other day I've discovered that a sky without a lot of detail works better in creating the feel of the originals. I'm happier with this image than with some of the other landscapes.
