How to render depth of field camera blur?
show user profile  Error1
I want to render camera focus / depth of field blur, but whenever i set it up it and it's displayed in the scene, it never appears in the actual render.

I have a target camera, and i've enabled Multi-Pass Effect on it, and selected Depth of Field from the drop down menu. If i click the Preview button it displays the blur in the work area, but when i hit Render it's not there anymore?
Theres also "Depth of Field (Mental Ray)" from the drop down menu, but that does not display it in the render either.

What am i meant to do? Thanks...

Do it in post. Use a zdepth pass, there is a tutorial somewhere on this site by MrGrotey.

Thanks for the replies.

I was just trying the zdepth / photoshop way. But the rendered zdepth image has no anti-aliasing ... i could blur it in PS but it dont do a good enough job. Is there any way to apply AA to the zdepth render or improve the edges in any way?

in the render elements window select the zdepth and tick the 'enable filtering' box at the bottom

Thanks mrgrotey that fixed it.

Last question... how can i stop lighting being rendered on an object? Because i have a photo on a box object, and just want the photo to look like it does originally, with no light or shadows or anything else being rendered on it. Not sure if this can be done?

turn the self illumination up to 100 on the material with the photo on it.
