Can you create real HDR images on freehand? Yes of course. Especielly if you can set the camera at automatic bracketing. Then it will quickly take three images with different exposures, normally you will use +/- 2 f-stops.
The image from the restaurant, the best cha siu restaurant in Hongkong, is taken on freehand. I used only two exposures and merged them in Photomatix. (Don forget to set Show settings for de-ghosting when you merge them). I used the fixed settings för Creative.
I used a cheat för the traffic incident in Shenzhen. I shot in raw, decreased light in highlights and white and increased light in the shadows. I also increased brilliance, and contrast.
