I am a beginner to Lightroom and just installed it to learn. But it seems I am up to a bumpy start. I have taken some photos using my Canon 50D in both raw and jpg formats. When I decided to import some photos to develop, when I choose a photo and then click on develop, it first converts my raw file to dng format and then the result is what you can see in the attached picture. I looked in preferences but could not find an option that can fix this problem. Be grateful if somebody could tell me how can I fix this annoying problem.
