Just started collecting my Studio Lignting for "Headshots" and portraits. As I'm in Pentax 67 system I can't see any other solution for the 1/30s flash synchro speed. So I decided to go with LED's. Found some cheep panes: Yongnuo YN-600 LED and Aputure AL-528 series. Need some info with to go with. I'm thinking to get 3 of them for headshot's and portrat's in studio and outdoor. Help needed what you think about this lamps. I have loto of flash power in studio but I don't know in with way to go with still light lamps.
