f2.8 gives a very shallow DOF. I considered the candle holder as being closest to the camera lens and should be in perfect focus. I started by creating an alpha channel with gradient fore- to background. I then applied lens blur to the image via PS CS. Finally to make sure the furtherest part of the background was even more out of focus I duped the layer, applied 5 pix of guasian blur and then with a layer mask painted the statue with the candle back into sharper focus.

Ronicox, I cannot see the larger image. Does the Lens blur filter really apply realistic blur? In that case, Adobe has solved the problem. See if you can recreate the original I have posted.

I don't know what you mean about seeing the larger image. Lens blur is but a tool that you have to learn how to apply. It gives you more options but my personal application comes from taking pix with a 60mm micro @ f2.8. Adobe hasn't solved any problems only given us the opportunity with more flexibility to solve our own. As to what you have posted, what is it you want me to recreate? I'm afraid I don't understand what it is exactly that you are looking for.

Hi ronicox,

When I "Click on image to view larger image" I get a big white space, no image.

My original challenge submission consisted of THREE photos, the f=22 that you have seen, the f=2.8 and the one that I have posted here afterwards with two versions of the plant. My intended challenge was, is it possible to create a Blur effect that looks like it was caused by a lens? Gaussian Blur looks like ... Gaussian Blur, as you can see from my comparison crop.

Looks nearly the real thing to me!
Mind you, I don't know what this image would really look like when taken with a camera.
