My 5x7 will go from 4" to 12" If the exposures are viable, I'd like to do
portraits, so I was thinking in the 10" range, but I see these charts that
show 'zones 1-11' define zones as 'color' but nothing useful.
what are the general exposures for a zone plate? given a specific focal length
are there different plates for different colors?
