I've been using LR 3 for a long time, and I love it. A couple of weeks ago I finally upgraded to LR 4. I do most of my images as HDRs, so I shoot multiple exposures for everything. My usual work flow is to import the images as DNG files, make the HDR, then import into LR 3 for the final processing. Since upgrading to LR 4, it been creating problems. If I import as ORF files, it works fine. When I import as DNGs, then make the HDR in Photomatix Pro, the following happens: [ame="http://s161.photobucket.com/user/guzziknight/media/Ridershill.jpg.html"]Ridershill.jpg Photo by guzziknight | Photobucket[/ame] I ran a test where I imported the same images using LR 3, and LR 4, both as DNG and ORF. No problems with LR 3, or when using the ORF from LR 4. But I had this issue with every image from LR 4 as DNGs. Has this happened to anyone else? Any ideas what's going on? Bad copy of LR 4?
