Sorry about not finding the Challenge are until after two weeks!

My real intention with thsi challenge was to find a DOF effect that looked more real then Gaussian Blur. I had therefore prepared a photo with a comparison, but it wasn't in the challenge.

But hey, does PS CS have a filter for this?

And fr those of you who assumed the candle bearer was in focus, that is correct.

Argh! I cannot edit the post Sorry for the typos then.

The left plant is the optical OOF, the right plant is the Gaussian OOF. Note that the real one has some circular artifacts and that the outline of the plant is "sharp" somehow. The same goes for the little cute angel.

So the real challenge was not to divide the image into three or four layers with different blur (which I assumed was a familiar technique), but to create a blur that looks like it was caused by an optical lens. Can it be done?

How? Tell me! The problem was I submitted three photos, but it seems the Challenge format can only support one photo, and then things started getting complicated...

However, I discovered TODAY that both Smart Blur and Dust & Scratches to some extent produce a blur more similar to "optical" blur than Gaussian does, so that might be an angle to try out.

yeap, cs has a lens blur filter, sorta like the filter combination engine in CS, define areas that are near, midrange, far etc.

oh yeah. being nearsighted really helps to understand realistic blur effects, the application you gave the pot was totally believable as far as visual acuity goes.
