You're not boring me. At least your mail didn't contain the word "ebay" :-)
Both TTL/OTF and Normal Auto Mode (computer flash) are based on surfaces
with average reflections (18 0rey) and rooms with average reflections. In
any other circumstance you must compensate. You compensate TTL/OTF flash
with the normal compensation dial; about 1 to 1.5 stop minus correction for
large dark places or backgrounds should do. You compensate Normal Auto by
selecting a different F-stop on the lens than the flash indicates (smaller
aperture for negative correction).
The GN of 20 may not seem much but indoors, used w/o a diffuser, directly
shot, it is a lot. At short distances (< 3 m.) an aperture of 8 is
recommended for films in the 100-400 ASA range.
Good luck with your wedding shots. If you're also shooting pics at daytime,
try some available light pics with fast film and lens.
