I haven't heard of this one either, but the answer is very very simple. Try it and see. If you don't like the effect, just undo.
Thanks for the response..
I'm thinking that it may be something that LR does on the fly.I was going to do as you suggested, but when I went back to dig into it the preset was no longer there
Was it a develop preset or a metadata preset? Those are the two types of preset you can apply when you import. There is no such preset in my LR 5.6.
It showed up as a develop preset when I was going bback over some older images. When I went back later it was gone. Unless it shows up again I'll treat it as a LR internal temp process that I happened to catch during my messing around.
It was just odd seeing it
