glow or diffuse

I need to know how to make an object glow or diffuse into the air around it, kinda like a haze or a lense blur. Is there anyway to do this?

You can use Radiosity:

or the Glow effect in the sequence editor:

Add >> Effect >> Glow.

using halo material is another option

thanks i’ll try radiosity

ok, ive made a test render for a scene im working on but it still lacks the quality i want. I need part of the scene to be out of focus, so is there anyway to create controlled depth of field in blender?

sure. there’s this depth of field method, or the zblur plugin.

The Depth of field tutorial wont work on an animation with camera moves will it?
