On the other hand, some post processing effects like lens flare and faked
focal blur need detailed information about the scene and could probably
best be done as part of the renderer.  Most modern renderers (like
Softimage, Maya, and 3DS) support a variety of post-processing effects.

But don't we all want that?  ;-)

Good suggestion!

Precisely Nathan, I can think of many creative uses for post-processing
'type' effects that rely on 'knowing' where an object is within a scene,
such as lens-flares that fade realistically as they becomes partially
obscured by another object, or how about having effects that vary in
intensity depending on their objects position ( so an object begins to glow
as it nears another ), or just having the option of applying an effect to a
single object within a scene which may itself be partially obscured,
something that would be awkward to achieve with an additional program on
just a still, never mind a whole animation. And I can't believe that it
would be difficult to implement such a set of options ( although I'm not a
programmer, so I could be quite wrong ).

Well, I'm not talking about 'hanging a bag on the side' of POV, I'm talking
about integrating post-processing 'type' effects ( possibly as additional
texture options ) in a way that would offer far more flexibility than
traditional post-processing would ( I speak as a hobbyist, not a
professional graphic artist ) - see Nathan's comments above.

I don't want to have to control every aspect of an image myself...I prefer
to be surprised by the outcome. I want to use just the one program, a
program that offers me an outstanding range of creative options. I want that
program to be POV.
