: plane { z, 50000

  Of course your camera is inside the plane.
  The normal of the plane points in the z-direction, ie. away from the camera.
The normal points outside the plane. This means that your camera is inside
the plane.
  Flip the plane:

plane { -z, -50000

  Now the normal points at the camera, ie. the camera is outside the plane.

There is, and a relatively simple one; add one word to the last plane.

Or to accomplish the same thing with an extra word:

plane { z, 50000 inverse

: hollow

  No, no, no! Don't teach people to bad habits.
  It's a good thing to understand the difference between inside and outside
and what's the inside and outside of a plane.
  IMHO the 'hollow' keyword should NOT be used to this kind of things.

difference {
  inside
  outside
}
error: No matching }in difference, undeclared identifier 'inside' found
instead.

  You have to understand what inside and outside are before you can make
their difference:

#declare inside = plane { y,0 }
#declare outside = plane { y,0 inverse }

Yes, I know.  T'was meant to be a joke; a literal interpretation of your
sentence.
Slightly more on topic, why does POV consider a light_source to be a 'patch
object' in the following code, when it complains about 'cannot invert a patch
object'?  Because it just happens to be lumped with the list of things that
don't have inverses, which happen to mostly be patches?
// POV warns about 'cannot invert a patch object' on the second line.
#declare ls = light_source {<2,3,4>,rgb 1}
object {ls inverse}

thanks for all the replies i tried it but why don't you just program pov so
planes are 0 units thick....

 There are very valid reasons for treating plane as they do most of which
have to do with the way they may be used in CSG operations to create solid
objects from. If you need a very large plane object you can instead use
a 2D box using the following syntax:

//This would be for plane {y, 0 }

box { <-1,0,-1>,<1,0,1> scale < 50000, 1, 50000> }

  For all intensive purposes the above will replace a plane object and you
will not have to worry about inside vs. outside.
