Free-viewing

[P3D Gabriel Jacob <jacob@xxxxxxxxxxxxxx>]

There has been some discussion recently about free-viewing and the effects
of cross vs wide eyed and the different ways to achieve it. Now again I
don't know if this has been covered in the good old days but haven't
seen it covered recently. So here goes.

In the above question that was posed, if the 50mm lens was taken at
the same time and beside the 80mm lens,and then the 50mm image cropped to
the same size relative to the 80mm, they would be in 3d. What I would
like to add to this is that you don't have to crop any picture if 
you can free-view. Just hold the 80mm image (if it is a print) farther
away till it is the same size as the 50mm image and you can fuse the 
2 images together. 

Here are two new questions (I hope)

1. Has anybody tried freeviewing the stereocards in the Imax movie
   Across the Sea of Time?
2. When we sleep can we see our dreams in 3d?

Gabriel, going to sleep to try an experiment in 3d.zzzzzzzzzzzzzzzzzzz
