Hi,
This is my first attempt at a HDR shot. Using three handheld matched photos. I seem to have lost quite a lot of detail/texture in the lane tracks, and also in the hedge (bottom left), and also not got quite as dramatic a sky as i was hoping for. But I'm guessing this could be because of my range of exposures? I also wasnt thinking as I took the shots and used a range of f stops rather than shutter speeds...
Shot at ISO 100, 1/60sec, f 7.1,10,14. After merging the photos I saturated it, decreased the exposure of the sky and gamma correction of the whole picture, used unsharp masks to sharpen it and increase the contrast, and then finally used levels to increase the contrast again.
