For those that are interested in ON1 RAW Nicolesy (Nicole Sue Young) has release 5 lessons in an ON1 RAW free tutorial series. I find them concise and to the point. Go to her website https://store.nicolesy.com and sign up. View the lessons online or download and view on your machine. She has also started a by invitation only Facebook Group as a support resource. Some post are just gripes that what is essentially ON1 RAW version 1.0 has some bugs and a list of features still to be delivered. Others group members are asking and answering questions. The Group has promise as a good long term resource. As a non professional I can afford to wait and see if the potential I see in ON1 RAW is delivered.
Are you using the new Lightroom; the version that's the same (mostly) on desktop and mobile? Then you may have noticed that a few features are NOT actually on both platforms. The ones that get me the most are Copy Photos (ie duplicate photos) and Batch Paste. I've found a way around it… in a round about sort of way. Check it out!
