[MF3D.FORUM:1141] Re: Deviation and Viewers

["David Lee" <koganlee@xxxxxxxxxxxxx>]

Mike,

Since you referred to me several times I will put in my 2 cents. I strongly
suggest that you make some shots with varying separations (noting the near
and far distances for reference) before you get too carried away with the
math. It's good to have a theoretical basis for what you're doing, but if
you get too involved in it before you actually shoot then you are wasting
your time. If I were shooting with just one camera I probably wouldn't
bother with calculations at all and would simply shoot 3 or 4 exposures for
each image, varying the positions so that there would be 3 to 6 different
separations to choose from. When you figure out the deviation you tend to
like, then you can work on making the formula fit with your perceptions, or
forget about it entirely. The variation of the formula that I talked about
at my workshop at the convention was based on simplifying the math so that
one could easily get results that were within an acceptable range. Steve
Berezin will have my handout on his website (it may already be there, but I
don't think it is).
