I know I’ve made images of this barn before; as I passed it today I figured I’d get a fresh one and try that Orton thing that Geren mentioned. The instructions he points to really lightened up the image, so I backed it off a little and had to play with the transparency to get it somewhat reasonable looking, and here for your evaluation (clicking on either should take you to a larger version, hosted by flickr) are the original and the “Orton” version:
It’s an interesting effect, I’m not sure how much I’d use it but something to keep in the bag of tools.
