My Nikon 5100 started saying IMAGE TOO DARK and TAKING BLACK PHOTOS. I tried several time to fix the camera: changing lenses, memory cards, battery removal, resetting holding down menu button etc. However, i call Nikon customer service and they FIXED my camera! Super easy..... Just press menu. RESET SHOOTING MENU select OK and presto like new again. Hope this works as well for you as it did for me. THANKS NIKON jr
