Hey Chucker, Doing post in Photoshop is a good way to handle still images as Nomuse notes. However, one of the tricks I pull out of the bag is to use Carrara's Light Sphere. Aura is problematic for one main reason - it's a post render effect in Carrara and that means that it doesn't show up through transparency or in reflections and also ends up with weird jaggies sometimes. In the sample above I've embedded two bulb lights in the fixture with the Light Sphere effect enabled. This way, the lights remain hidden and don't show up as those annoying spots on reflective surfaces. Additionallly, the Light Spheres render around the modeled light and show up in the reflections on the walls and floor since it's an actual render-time effect. For simple glows, post render in Photoshop or PSP is faster because you don't have to tweak the Carrara scene. But for more complex requirements or animations, the Light Sphere is a nice alternative.
