P3D too much depth

[CanterMike@xxxxxxx]

The concept of "too much depth" has arisen lately, to which Mike K comments:

<<  It's possible when one perceives that an image with enhanced depth
becomes surreal to the point of not liking it.  Purely judgemental
and personal.  >>


I must contradict the "judgemental & personal" part. 
I'm not sure I'll phrase this correctly, so if any of The Masters disagree, 
please correct me.
 
"Too much depth" occurs when the left and right images exhibit excessive 
deviation, to the point that you may feel strained in attempting to fuse the 
images.  In extreme examples you may not be able to fuse all of the image, 
but will get a pronounced double image of some portion.

I was recently had the honour of assisting at the Chesapeake International 
Stereo Card Exhibition.  After the judging was completed, I was able to take 
some few minutes to examine every entry.  Several cards demonstrated this 
effect (defect?) quite well.  In one example, I  was able to fuse the 
foreground portion of one, but was unable to twist my eyes enough to merge 
the background.  At least two other people commented on the effect.
