If i put my camera in 'M' the flashes also go onto manual i think?

But if i am using a STE2 and have ratio selected (using more than one flash), will this alter flash power or do i have to manually set the power on the flash?

thanks in advance for any help,

Chris.

For the most consistant results put the camera and flashguns into Manual mode-however i have had good results using an ST-E2 with the flashguns in ETTL
