Guys
Like many of us I've been using LR for many years and, to my mind, it just gets better and better.
I was impressed with the relatively new Mask editing facility but I did find the Select Subject option slightly hit and miss for u/w use.
I don't know if it was due to the latest update (a few days ago) or AI doing its thing, but editing in the last 24 hours using the Select Subject option has blown me away. See the attached shot of a Spotted Cleaner Shrimp. I clicked on Select Subject and the blue highlighting shows just how good this option has become. It's got the whole critter, feelers, antenna et al.
I thought I'd pass this on.....
