As I begin my venture into off camera lighting, the commander mode on my D90 just isn't cutting it in bright light. I come the the question; Do I want to use radio syncs or do I want to use a sync cord. The worry I have with sync cords is the length and that I wouldn't be able to get the positioning that I want. The worry I have with radio syncs is not having the iTTL capability. What are your opinions?
