Oloneo is one of the newer pieces of software for creating "HDR" images which it does quite nicely I must admit.
What I was curious about was taking a single RAW image and getting the most "Dynamic Range" out of it with just one photograph. Oloneo does this quite nicely as you can see in the above two pictures. I set the camera to take one RAW picture and one Large/Fine JPEG image all in one shot. The top picture is the JPEG as shot and the bottom picture is the RAW picture processed with the Oloneo software. Can't see that much difference until you view the pictures larger.
The program is free to try for 30 days which I am doing now... 28 days left to go.
