Radial Filter Before and After

Adobe PhotoShop Lightroom version 5 was released in June, and I’ve been digging into the new features. In this article I’ll share some tips for selective editing with the new Radial Filter tool.

The Radial Filter allows you to draw an ellipse around an area of an image, and apply edits to the area outside or inside the ellipse. This is a great technique for highlighting portions of an image.

Keyboard Shortcut: Shift M

If you read my article on improving your Lightroom workflow, you’ll remember that I’m nuts about keyboard shortcuts. The shortcut for accessing the Radial Filter tool is Shift M. Just remember that the shortcut for the Graduated Filter is M, so Shift M makes sense for the new Radial Filter. After all, if you took a Graduated Filter, and curled it into a circle, you’d have the new Radial Filter tool.

Using the Radial Filter Tool

In the above photo of my son enjoying a summer day at the pool, I used the Radial Filter to make the water a little darker, and a little more blue, without changing the exposure or white balance over the subject. This has the effect of emphasizing the subject by making him brighter and warmer than the rest of the image.

1. Select the Radial Filter tool and draw an ellipse around the subject. Start by clicking at the center of the subject, and dragging outwards.

2. If necessary, rotate the ellipse. Hover your mouse just outside the ellipse until the cursor changes to that rotation indicator thingy, then click and drag.

3. Apply the desired settings. In this example, I’m cooling the white balance, reducing exposure, and increasing contrast, highlights, and clarity. Increased clarity often make water look more interesting by bringing out the reflections.

4. Feather the adjustment. Feathering the adjustment is important to ensure your image looks natural, not “Photoshopped.” Feature is 50 by default, I’ve found that for more image, I like it around 85 or so. Note that after increasing the feather, you may need to back and increase the size of the filter.

Inverting the Mask

When the Invert Mask box is not checked, your edits apply to the area outside the ellipse. If you check the Invert Mask box, your edits apply to the area inside the ellipse.

Conclusion

By varying the exposure, contrast, and white balance of the subject, relative to the setting, you can direct the viewer’s gaze and increase the impact of your photo. I hope this simple example has given you some ideas of how to incorporate the new Radial Filter tool into your workflow.
