[MF3D.FORUM:1180] How much shift can be necessary to set the window?

["Michael K. Davis" <zilch0@xxxxxxxxxxxx>]

Hi!

For folks using 6x6 cameras to produce your chips for 50mm x 50mm RMM
mounts, for example, do you ever find yourself wishing you had more of a
margin horizontally, for setting the window?  I'm considering a larger
mount, using 6x7 chromes.  My camera produces a 55x68mm image.  Ignoring
any other "gotchas" for the moment, does anyone think a 50x63mm window is
too large, horizontally?  I know that only leaves 2 mm between images, if
centered at 65mm, but I'm more interested in getting feedback on whether
having only 2.5mm all the way around is enough for setting the window in
most circumstances.  If not, how much smaller than 63mm would you design it
to have enough to handle most situations and still meet the goal of
enjoying a larger format than 50x50?  6x6 users don't have much more than
2.5mm all the way around, right?

Thanks!
