OK, I'll admit I found this tip while web surfing, so it isn't directly from my mouth... lol! :) But here it is:

It came from a HOW Magazine's weekly e-mail that I saw posted on another forum.

ADOBE TIP OF THE MONTH: Making a Photo ‘Pop’

Make the subject of an Adobe Stock Photo “pop” by altering depth of field. Photoshop’s Lens Blur filter creates this effect. Use a simple selection to determine which areas are blurred, or provide a separate alpha channel depth map to describe exactly how the blur is added. Choose File > Browse to begin an Adobe Stock Photo search from within Photoshop.

Using the Lens Blur filter:

1. Choose Filter > Blur > Lens Blur.
2. For Preview, choose either Faster (generate quicker previews) or More Accurate (view final version of image).
3. For Depth Map, choose a source from the Source pop-up menu. The Depth Map creates a natural effect by gradually changing the depth of field appearance.
4. In the preview image, click on the photo’s main subject to bring the depth of the clicked location into focus. The Blur Focal Distance slider changes to reflect the clicked location.
5. Choose an iris from the Shape pop-up menu. The way the blur appears depends on the iris shape you choose. Drag the Blade Curvature slider to smooth the edges of the iris, or drag the Rotation slider to rotate it. To add more blur, drag the Radius slider.
6. For Specular Highlight, drag the Threshold slider to select a brightness cutoff; all pixels brighter than the cutoff value are treated as specular highlights. To increase the brightness of the highlights, drag the Brightness slider.
7. Clicking OK applies the changes to your image.



** OK, off to try a lens blur. I'll admit that I've used motion blur, gausian blur, but never lens blur... lol! :)

I look forward to your tips every week, so glad you take the time to share with us! There is a great video tutorial on that very thing this week on Photoshop TV at http://www.photoshoptv.com/ starting about 2 minutes into the show. Scott shows how he uses channels, the gradient tool & the lens blur filter to give a nice gradual effect.

Thanks Ange! :D
