Hi, I've scarily just forked out on the Yongnuo YN568 ex flash for my Nikon D3300. I'm wanting to use the flash off camera so know I need a triggering device. I'm just a bit confused by which one to get. If I get any Yongnuo trigger will it be compatible with the YN568 flash? I've seen recommendations for the Yongnuo YN-560 trigger as you can control the brightness of the flash when it isn't connected to the camera. But will that one be compatible with the YN 568 flash? Is there anything else I will need then. The Yonguo YN 568 seems to have a build in receiver I think. Any advice would be amazing, I know I've been on here asking for a lot of help recently!
