         I used the guage, and that is rarely the problem....  for some,
this would not be a problem but I notice sometimes I have to look at the
image for awhile to make it fuse, or sometimes I get part of the scene to
fuse then when I move my eyes around I need to focus to make that part
fuse....  I think the 50% correction factor used in Mike Davis's formula
will correct this, I was to bold in the begining!   I have viewed some of
Mikes shots, and he used even less correction and his fused very well... so
I am convinced this is the problem....

            YES!  Isn't that odd, I notice a lot of cardboard cut out
things, but I rarely ever see any miniturization.... I still do not have a
clear understanding of what causes this... do Spud and Rolleidoscope users
see this too?  I think it is related to stereo base also...???

        NO, I should have explained this one...it has been my experience
that the wider the base, the more potential for different effects in each
chrome.  For example,  the sun will be cracking through the leaves in the
left chip at a slightly different location than on the right chip...  each
camera is seeing things from a different vantage point...the wider the base,
the greater the differences...  same as if you must moved your eyes 20" over
to the right....  Wider bases = greater prone for these problems... but when
viewed, its still retinal rivalry.   Also the wider the base, the more risk
of getting something in one image but not in the other...for example, one
chip showed a telephone pole from the ground up, the other chip had a
building blocking the base and only showed it from the top of the building
up...more retinal rivalry...

        I will sort through some of mine in the next month and send you
some....
