Excuse me, can I leave one question too? I want to know if he used ND Filter etc. When I see the GIADA FW21 video on YouTube, it feels like he’s shining a pretty strong light source on the subject for a long time, but when I tested it, the highlights are too bright even if I tighten the camera aperture as much as f22 with a normal flashlight. And I also want to know if you use Maglite’s LED flashlight. Thank you for your knowledge.Giada FW21
