I have used the new feature of HDR on a number of images. To my joy I've realised that Lightroom CC can work on a number of different image and files in the background together making them in HDR files, much more better and realistic than Photoshop's HDR feature. When ready Lightroom places these HDR files directly in the catalogue and saves them with the original bracketed photos. Very very convenient! Yet I'm discovering that when later on I go to open these HDR files from Lightroom CC, the program crashes. Not all the time yet very frequent. Any ideas?
