Explore the exciting new tools in the free beta of Adobe's Photoshop Lightroom 5
Another new tool among the selective adjustments is the Radial Filter, which allows you to select and apply adjustments to a circlular or oval-shaped area. It’s a great way to draw attention to a given region of your image. To bring out the flower, use the Radial tool to select it. Check the Invert Mask box to work on the thing you circled, rather than the area outside. Up the Shadows and Clarity to make the rose pop.
Radial Filter Tricks
This filter can be useful for quickly selecting a region when you need to fix the white balance in mixed-lighting scenes. Use it with Sharpness to add blur to everything outside your selection. Add multiple circles to duplicate an effect in more than one area. And, yes, you can desaturate the whole image surrounding what is circled—but we hope you will do so sparingly.
