For those who are doing HDR don't push the effect too far or else you get a sky that is dirty looking and has banding. Try this instead: after you do the effect bring into Photoshop the HDR image and the original photo and addthe original as the top layer, next place a layer mask on it. Paint out the of the mask the part of the image that you want to show from the HDR photo. Now that you can see the two layers together play with the original to make it a cohesive photo by using adjustment layers (this will not destroy your photo's). Good Luck!
