Thanks, I.D. for the heads up.
Adobe's adding a brand new selection tool to Photoshop CC (more to come on June 18th).
A cool tool indeed! Selects on the basis of which pixels are and aren't in focus, and can be adjusted with the "Refine Mask" option.
For a good idea of what theis new tool can do, watch this video...and stay tuned for Adobe's event on June 18th for more.
