Much more grain, higher contrast, less sharp (though it is the sharpest
of the 200-rated slide films), richer colors - a great film for aerial
work (especially if old, since it then has a bit of a "skylight filter"
tint...), murky-hazy days, evening foliage photos. It is decent for
other uses, though I would be inclined to choose any of the several
excellent Kodak/Fuji 100-speed slide films for most of those (but
definitely NOT the other Kodak/Fuji 200-speed slide films...).
Hope This Helps
