Thanks Elliot:
And then from ACR, you use the Save image Button on the bottom left, and save to a new folder? That is new to me, I've always clicked Done on lower right, and just overwritten the jpegs, which is probably stupid. But if you are on anything other than jpegs, Tiffs, Raws, then Done is ok, correct?
Rodney, I just got on board CC, how does the filter work? It's quicker/ easier than Elliot's method?
