[MF3D.FORUM:779] Re: Deviation

["don lopp" <dlopp@xxxxxxxxxxxxxxx>]

s to focal lengths of lenses I am using. I am at a total loss also as to why
deviation should be determined by a mathematical formula I thought we had
eyes and a brain to figure out such things. According to THE formulu I have
shot a couple thousand  slides using the wrong deviation -three years later
the errors of my ways are pointed out to me by persons who may or may not be
speaking  with the advantage of any experience in the field. An example of
poor thinking is this idea that the interocular should be 65mm. I was using
twin Leicas in 1955 using 28mm Summarons spaced 6.5 inches apart and have
never heard any complaints. When I have complained about too much hyper I
complained usually about weeds in the foreground but I attribute most of the
blame to the poor view-finders put on most cameras SPUTNIKS, most 35mm
stereo cameras including RBT probably the worst was the Verascope F 40 .
Most have overcome these obstacles over the years and I am allways happy
when one of our slide shows is one by someone using an old  3.5 Realist with
out all the bells and whistles of an RBT or a modern S L R-. GOOD pictures
are usually good enough that most imperfections are ignored by most .  I
have seen the works of Greg,Sam,Tom D Paul and Dick T  but the rest are an
unknown qauntity to me and I wonder as to how many of the others have ever
seen quality M F slides { this is not easily done with a Sputnik }
