Matt - I am metering through the filter (Leica MP).

Macy:
Now I understand why you had so much grain.
When you meter through the filter, your meter takes into account the neutral density of the filter (about 4 stops). If you also adjust the ISO of the meter to 12, you are again adjusting (by about 4 stops) to take into account that neutral density. Together, the adjustments total to about 8 stops - you ended up overerexposing your film by about 4 stops.
In short, if you are going to meter through the filter, it is appropriate to use an ISO at or close to the "box" speed of 200.
I use the word "about" through these observations, because of the issues of spectral sensitivity - your eyes see the spectrum of light one way, the meter sees the spectrum of light another way, and the film sees the spectrum of light a third way.
Hope this helps.

PC, I like to use SFX in the summer when the leaves are out. Depending on the species of vegeatation, leaves turn a bright white with SFX, and IR filter and bright sunshine. Some of the shots posted are good examples.
Never shot SFX in the winter. Hmmm, could be fun!
Dear all,
When SFX 200 was withdrawn during the administration of the former company in August 2004 we got loads of calls from architectural photographers who used this film to photograph buildings...obviously the extended red
gives the image a unique look juxtaposing the sky and buildings, so if you are giving it a try don't just do the usual sky and scenery try a bit of architectural .
