I was shooting some images in Raw and I wanted to work with them in HDR. They look good on the computer from light and dark exposure. But when I work with them in CS5 or Lightroom 4 they do not have any different tones, like they are stuck in the middle. Thanks so much John S.
thank you all for your comments, figure out what was wrong. I load my images on an external hard drive, I decided to load them on the main hard drive, then import them to lightroom, and it work. Must had glitch in the external
