I haven’t seen petrified forest before. Well, technically I have not seen it last time in Utah, either. Just this year, Southern Utah received well above average of snow, and I happened to be there middle March, a day or two after last snow storm. Escalante Petrified Forest State Park was basically closed, and all I could see was a representative display at the visitors parking. Not much, but gave me some ideas what petrified forest is about. And several nice photograhs, which I thought my need some Details Enhancement. And believe it or not, it was done without use of Photomatix. Just smart Lightroom Details Enhancer preset (sorry, I cannot find the source of the preset right now. If you are the creator, put the link in Comments, I will be happy to add it to the post).
