I use RAW Power and like it. It is inexpensive, and it uses the Apple raw engine as Aperture did - so if you like the Aperture RAW conversion and editing controls, you will like RAW Power. Version 3 of RAW Power is due out later this year - new features are being added all the time. Nik Bhatt (the developer - and former Aperture Manager at Apple) is very responsive and listens to users. Highly recommended,Has anyone tried RAW Power from Gentleman Coders? It's a plug in for Photos that provides editing tools for RAW images and generally gets good reviews. I shoot a little RAW, and I've had concerns about using Photo as the DAM tool instead of Aperture, particularly with large RAW image files.
