Yes, I use it all the time, for small details. But the problems I've been having lately are when I've used terrains to create mist, I find that the edges of the terrains show odd downward streaks, so I'm quite glad to think (hopefully not mistakenly) that the PhotoShop DOF technique will give me the right focus on my main object without trying for days to make good mists - only to end up with funny streaks when I though I'd finally cracked it! (sigh)
