Hi. I'm looking to buy a couple of Yongnuo flash guns . One with ttl to go on the camera (Canon 650d) and the other to sit elsewhere . Question is/are which models? And what do I need to fire the second unit? Will built in optical firing suffice or some radio remotes? It's been along time since I've messed with lighting, and ( pardon the pun) feel a little in the dark about it all..
Thanks in advance. This is by far the best forum for intelligent, and not so responses.
