X-TTL A/B ratios and group sequence
I was waiting for an update of the documentation, but several months later there is no changes. Can you give some tips and guidelines about the new ratios funcionality?
I asume that the flashes on the A channel are measured diferently of the flashes on the B channel, and the system decided the amount of light needed based on the relation that que can specify on the Cactus V6II module (1:8 or 8:1 as example).
But I´m not sure about the limits, the meaning of the numbers( I assume that 8:1 is a relation of 3 stops to one), how that affect to the performance of the flashes, etc.
I detected some inconsistences using this new funcionality, but I think the problem was I was to close to the low limit of the flashes (RF60 and RF60x), so it was no possible to the system to use a lower intensity,and, of course, not able to balance both flashes as I specified. Knowing what is the expected behaviour can help us to use and debug the x-ttl ratio funcionallity.
