Rather than white *spots* I'd call them flecks, characteristic of
cyanotype & VDB on Rives BFK. Can't say of course if that's what Lukas
had, but they caused me to advise against BFK for either medium. Some
folks use both these emulsions on BFK without a problem, which could be
due to their different method of application, different pH, different
climate, and/or X, Y, & Z.
