Yes indeed practice is needed. It was only one speedlight. Any input on how and where to place it to avoid hotspots and such? Its really hard to do with the being a dark shade. I do use a CPL but then again, in the dark its difficult to see how much reflection was killed or if i need to rotate it in order to get rid of most of the reflections
The effect looks cool, but since I don't really know what strobing is, I can't say how well it was achieved. How does this technique work what is the goal?
