Hi Paul, I could be wrong ( I'm not very good with photoshop) however I don't think you would get a true HDR image by merging 3 images in elements. I believe that there are plug-ins for Adobe that enable HDR (but don't know if you can use them for Elements). You can download either Photomatrix or Dynamic photo HDR. Both can be used as stand alone programes and are free to try but leave a watermark or you are unable to save as HDR, I've played with both of these programes good fun!
