Just so there is no confusion, as I stated in my initial thread I'm not wanting to use ETTL. I am wanting to use these just like studio strobes for location shoots. I don't have a problem metering the flash units as long as I can figure out how to adjust each one to the desired output.
There are two ways you can set the EX flashes to manual mode in a wireless remote configuration. In both cases the master is set to Manual mode. The difference is how the slave is set.
With the first method, the slave is set to ETTL mode and its output is controlled via the master. On the master, turn ratio on (either A:B or A:B:C depending on how many groups you want to use) and then set the master and slave power outputs on master.
With the 2nd method, the slave is set to Manual mode. Since the flash will not immediately switch to manual mode when it is in slave mode you will need to hold down the Mode button until the letter "M" flashes on the LCD display (the M will continue to flash in this mode). Once it's in manual mode you can set the flash power output on the slave flash itself.
Since you said you'll be bouncing the flash off an umbrella, you'll need to rely on a flash meter to get the correct output for the ratio you want.
