P3D Re: OVERLAPPING IMAGES OLD AND NEW

["Dr. George A. Themelis" <DrT-3d@xxxxxxxxxxxxxxxxxxxxxxxxxxx>]

Thank you Alan for the very interesting analysis of the
overapping frames in both old and new equipment!

A few months ago Mark Dottle and myself posted our impressions
and reviews of the RBT X4 cameras that we got.  We noted this
advance sequence "feature":

>I get spaces between images of 2, 0, 2, 4mm repeating.  

I was not aware of this problem:

Because I do my own mounting.  Others have not reported problems with
commercial slide mounting or printing of RBT films.  Why so?

Any other X4 tips to share?
