The updated masking feature in Lightroom is one of the biggest and most impressive updates in a very long time. it has literally changed my workflow and cut down my time in Photoshop quite a bit.
In this video on the Wild Eye YouTube channel I walk you through the basics of all the different kind of masks and then, at the end, share s few tips and tricks you could use in your own processing.
Good luck with your processing and please let me know of I can ever assist with any of your photographic or post processing questions.
Happy editing, stay safe and don't forget to be awesome.
