Can someone please offer some help/advice. I have a Canon 60D that I use with an older light set up that I've had for probably 8 or more years (studio max III 320 by photogenic). Photography is just a hobby so most things are trial and error for me. I recently purchased a set of Yongnuo RF-603C II wireless flash triggers.. Hoping to get rid of the sync cord and hot shoe set up I've been using. Not sure what I'm doing wrong but I cannot get the triggers to work! Seems to work with the lights and will test fire but once I hook up to my camera... Nothing! Is there a setting I'm missing, a different cord I need or are they just not compatible? If anyone can help, I would be very grateful!
