I'm going towards portraiture at the moment and currently deciding on a Flash to get.
I'm using Nikon D90 and stuck with 2 options; Yongnuo YN560 (Manual) and Nissin Di-622 Mark II (TTL). I need your opinion on which would be a better option as a first Flash unit. I am a beginner to Flash but not to photography in general.
I don't mind paying double the amount for the TTL function if it is useful, so need your input whether TTL function is useful for beginners in flash photography? Or is it better to start with Manual?
Your help is greatly appreciated!
