Panning reverb?

What did you hear about reverb panning? Are we talking about how reverb distributes reflections across the panorama, how reverb preserves or does not preserve pan position of stereo and/or mono inputs, whether or not a reverb sums left and right before generating reflections, or using panning as a special effect or widening technique?
 
In lieu of clarification, I'll take a blind shot at the question...assume that the output of a reverb plugin is probably stereophonic, in which case "panning" has no meaning. But depending on how you want to manipulate the stereo image, inserting Channel Tools after the reverb would be the usual starting point. That will allow you to either narrow the reverb tail's image, or use M/S mode to widen the reverb by boosting the sides.

another way I've done it is create two aux sends and insert two disparate reverb plugins.  On the track you want to effect- create two sends- one for each reverb.  Pan the output of each hard right and left.  It works best when the settings are 'similar' like a Breverb Hall and a Lexicon Hall. 

Thanks for the responses, guys.
 
In answer to bitflipper's question about what I heard.... I read here and there about it, without really knowing what it meant. I've since heard an effect on recordings which I assume the term refers to.  An example of the effect is one I heard recently, where a vocal was panned straight down the middle and it had reverb added, but the reverberations just went off to one side, rather than all around.
 
 

sharke you actually should read some previous posts.  I have covered that concept already. Then you can save yourself some time repeating what has already been said.

Another option  (and I sometimes do this)  is to let a reverb create a stereo output but use Channel Tools on the output of the reverb.  Narrow the stereo image right down and then place the reverb at say 2 O'Clock and the mono source signal at say 10 O Clock.  That can be very effective sometimes.  You don't always have to have the reverb outputs in full stereo right across the stereo pan field either.  ie actually position the reverb in the stereo field.  In a complex dense mix that will stand out more than the usual stereo return concept.

I don't even know where to start here, Jeff. What is Channel Tools?

The concept of panning, in the conventional sense, has no real meaning when it comes to reverb.
 
A reverb plugin emulates a natural acoustical phenomenon: audio bouncing off walls. In an acoustical setting, that means delayed versions of the sound arrive at your ear from many directions, including the opposite side from where the original sound emanated. To simulate this with artificial reverb, the processor applies random panning to each faked "reflection". You can usually control how much of this effect is applied, via the reverb's "width" setting.
 
Panning is therefore an intrinsic function of the reverb unit or plugin. You can mess with it after the fact, but you're really just defeating part of the overall effect. There are legitimate reasons for doing so, but not many.
 
For example, if your reverb plugin lacks a Width adjustment you might want to narrow or widen the reverb tail using M/S processing (that's where Channel Tools comes in). I sometimes use an autopanner or chorus on reverb as a special effect. I've also used a pair of mono reverbs, hard-panned, again for special effect.
 
But for the most part, reverb usually works best when you just let it do its own thing with the panorama.

Ooo the snark! To be fair though, you talked about narrowing a stereo reverb image, not making it mono.

Even if you're saying the same thing as another poster but in a different way, one might be easier for someone like me to understand while the other post might just confuse me more than I already am. There's room for everyone.
 

Your potentially interesting but more or less useless reverb factoid for today is that there are very few stereo reverbs. Most sum the inputs, then generate stereo reverb from that.
