A couple of years ago I came across Camiel Schoonen’s very well-done set of antique presets for Lightroom/Lightroom 2 (link to flickr discussion page for the presets). They achieve some nice effects, as in my example below from a ride on the Grand Canyon Railway. The modified photo is on top, original beneath:

After a laptop transition gone awry, Camiel lost his copies of the presets, but I still have a copy. I’ve forwarded these back to Camiel so he can resume their distribution over at his own site.
Thanks for the great work, Camiel!
