DOF image

[Tommy L]

Dont use DOF too much, bit concerned about the graininess. Is AA or DOF sampling to blame?

Thanks,

Tom.

The DOF sampling controls this, but to be honest I wouldn't get too hung up on it. If you look at any real-life image with a shallow depth of field the grain is much more evident in the out of focus areas.

And, if you are really concerned about the grain, the cleanest way is to create a depth map and use it with the Lens Blur in PS.

2nd that! Lens blur is such a cool feature in CS3, been playing with it loads recently. Just paste your z-depth image in as a channel.

If youre doing it in post a lot, i'd try to spring for rosenmanns DOF pro - it does a very good job of it.
