I have a PC-to-hotshoe cord that allows me to use my Canon 580EX with my Hasselblad 500 C/M. I also have a Sekonic L-358 light meter.
The Canon flash for those unfamiliar is their top line flash unit, and it has a fully manual, non-TTL mode. I know its guide number at various focal lengths at full output, and the output can be decreased in 1/3 stops all the way to 1/128 of full power.
What I want to know is how I can take readings from the meter (presumably in Ev mode) and use them to determine flash output with the 580EX. I'm a bit lost with all this, and it shouldn't be that hard. I don't have the time to get a more typical Hassy flash unit right now before I'll be on vacation hoping to use this combination.
Thanks.
