    Hello all,

    I am using a D200 and recently purchased an R1 lighting system. I am wondering, is it possible to do flash ratios on the D200? I have noticed that you can only make an adjustment to EV.

    Can I simply manually change my EV for each group to produce my desired ratios? I assume yes, but I do not know if the relation ship between EV for each group is linear.

    For example, if group A is -1.7 and B is 0. What would the ratio be?
