Current release of Photoshop has more than a dozen new features that significantly widen our choices in working with images. Sharpening tools, Camera Raw Tools, improved tools for working with vector objects, copying of CSS attributes, improved toolbar for working with 3D objects and texture painting, and much more are now available in Creative Cloud.
All-new Smart Sharpen
New Smart Sharpen filter (Filter > Sharpen > Smart Sharpen …) gives us an opportunity to improve image sharpness while minimizing noise and halo effects. In the filter’s dialog box, you can control the parameters Amount, Radius, Reduce Noise and choose what type of blur need to be eliminated.
In addition, you can control the amount of sharpening that occurs in shadows and highlights.
