So given that one would use an "opaque" filter over the flash, what
method of exposure control is used for this? On an EOS 1n, (which I've
never used with flash- but we've all got to start somewhere) what is the
setup? Is this TTL flash metering or something else? 
W-J, you must have an answer for this one...
