This app does what the developers say it will do. The lens correction feature works well. The suggested changes it makes are immediately viewable by toggling the M key for comparison with the original. I experienced no issues using it with a batch of 50 raw files. I followed DXO’s suggestion to process the raw files in their app before doing additonal editing. As suggested by others, a batch processing option would be useful but that’s probably a Photos feature problem rather than a DXO issue. I’m an experienced Aperture user and have used many plug-ins and external editors over the years; this one is a keeper, especially for the price. It adds very useful editing tools to the otherwise limited Photos app which I anticipate will continue to improve as Apple refines it in subsequent system updates.
