P3D Stereo Rules

[Bob_Maxey@xxxxxxxxxxxx]

Perhaps the word "Rule" could be changed. A rule is just that, a rule. When
a rule is challenged because of so many exceptions, then it becomes less
like a rule and more like a guideline. Fact is, you can't tell what rules
or separation guidelines were followed from looking at many images. If I
separate say 3 inches rather than 2-1/2, and my mounting is changed, the
viewer is left with good looking images in stereo with no perceptible
changes in some of the factors everyone is discussing. I have read on a web
site that there is such a thing as "Too Much Stereo Depth". How is this
possible?

Do any of the rules proposed in this discussion serve to help eliminate
that pesky problem that has plagued scores and legions of Stereo
Photographers for eons? I had someone ask me about this term and how it
applies to the rules, and I just do not know.

My point is that if I am taking pictures of small objects - 2 to 3 inches
or so, I can vary my separation to either side of the ideal separation
described in all the math, and the stereo is still good, the images look
nice, and since I have not followed any specific rule, what difference is
there? If I shoot stereo images or large objects, same outcome. If I take a
general stereo scene of flowers, statues, whatever, I could make my
separation a bit wider or narrower, and you can't tell any difference.

Finally, if any of you want to use charts and rules and formulas, fine. If
it has an effect on the results you are getting, great. I would think that
if there is a basic rule that helps, rather than arguing, post some valid
information based on tests you have made. Perhaps then the argument and
discussion can turn a bit more friendly.
