Hi there, I was wondering if anyone can help me with controlling the flash output with the YN 568 EX N . Basically, I have a YongnuoYN-622N-TX i-TTL Wireless Flash Controller on a nikon D750.....and two off camera flashes, one being the YN 568 EX N and the other being an SB700 (Both on a Yongnuo`s i-TTL YN622N Transceivers). I have set up both the channels as A & 1. They both work fine in manual, BUT, I was wondering if anyone knows if their is a possible way to control the output of the flash from the YongnuoYN-622N-TX i-TTL Wireless Flash Controller on camera, rather than having to set the YN 568 EX N`s flash output by hand? Any help would be greatly appreciated! Thank you!
