Good morning all, I hope someone can help me. I shoot with a Canon 5Diii and use Quadra Rangers as well as RX600s. As well as the Elinchrom triggers I have Pocket Wizard Mini Flex triggers. Ok, so the problem I have is that I need my flashes to trigger on second curtain sync after a long exposure. The camera says NO but I am sure that there is a way to achieve. Any help will be greatly appreciate! Thank you
