Mea Culpa! The inner quotation was me, and that should read correction
factor, not stops. Correction factors are used by multiplying shutter
speed with them. Translated into stops, it's about what Roger mentioned,
between 1-1/3 and 1-2/3 stops, with YMMV depending on who made it (some are
darker than others).
