I am trying to learn what can be done using HDR Toning in Photoshop CS5. At first I was impressed by its capabilities. I was working on a photograph of a train in a wooded valley in eary spring (before most leaves were out), with bright sunlight coming from almost straight overhead. So, the top of the train and the ballast in front of the train are very bright, the woods to the sides were shadowed, and the sides and nose of the train were in deep shadow. HDR Toning seemed to be giving me very nice control over adjusting the various tones. But when I closed the HDR Toning window, PhotoShop thought for a couple of seconds, and then changed my image, making it much darker than it was when the window was open!
What's going on here? Is this expected behavior? How can I get HDR Toning to keep my photograph from changing after I close the window?
Thank you very much.
