Ex­tract With chan­nels

3D World - - TUTORIALS -

I of­ten use chan­nels to ex­tract out sky and other el­e­ments, pre­fer­ring it to the Magic Wand Tool and the like. There is a lot more con­trol in paint­ing in the sec­tions needed by us­ing the Color Dodge and Burn tool af­ter copy­ing the chan­nel that has the most con­trast for the el­e­ment that needs to be ex­tracted. I also use tool pre­sets such as soft brushes set to Color Dodge or Burn if I need more harsh paint­ing. This is be­cause the Color Dodge/ Burn tools have their own au­to­matic ranges of High­lights, Mid­tones and Shad­ows that you must se­lect be­fore paint­ing, but I per­son­ally pre­fer be­ing able to paint with the Wa­com pres­sure sen­si­tiv­ity. Once I have a mask that I am sat­is­fied with, Ctrl-click­ing on the thumb­nail of the chan­nel loads up the se­lec­tion that can then be used to cre­ate an au­to­matic mask.
