Getting used to but quite reasonable, effective and logical workflow in Lightroom, the fundamentally different from all I know programs. Any changes to the photos are non-destructive and can be at any time zuurücknehmen. Only when a photo from Lightroom "exported" will be permanently on that amendment. But DBEI remains unchanged made the original in Lightroom. There are a zillion great features that you do not know of other programs. Who in (American) is a firm grasp English, I recommend the video tutorials on the Adobe website that are truly outstanding.
My conclusion: Despite the lush price for the rather meager upgrade I am very satisfied. Meanwhile there is an update to version 5.2 with several new features. Who wants to indulge sichs who should buy (but maybe wait until it is time to have favorable).
