There is a really good trick to using the inverse command effectively in Photoshop. In certain instances it’s easier to select the area that you don’t want affected and then select the inverse command. This is a good method to use when you’re working with more simplified backgrounds or bright blue skies. I’ll walk you through this method using Photoshop.
Refining a Selection: The Inverse Command
To learn more I've created an exciting course called Practical Photoshop Selections with Lynda.com
Take charge of Photoshop and make better, more targeted image adjustments with selections—including hard-to-select objects like hair, fuzzy edges, and color ranges. Rich Harrington reveals the importance of precise selections, whether you're masking, changing color and tone, or even storing transparency, and shows you how to make them with the tools in Adobe Photoshop CC. Dive into the Select menu commands and the Marquee, Lasso, and Magic Wand tools, and then learn how to refine your selections with Expand and Contract, Smooth and Feather, Quick Mask, and other controls. Photoshop power users will also enjoy advanced techniques involving the Color Range command and alpha channel selections.
Topics in this course include:
- What are selections?
- Creating masks from selections
- Moving a selection
- Selecting with the Quick Selection tool
