Recently i did a studio photoshoot with my friends. Everything is fine except when i change to a certain shutter speed, it gives me a thick black strip across the photo. Why is it so?
1/250, f8, flash: Rear wb: Auto
For some reason, upon setting the shutter speed at 1/200 and below it works fine. What are the cause of it?
Using 2 Elinchrom BX500RI both left and right of his face and another BX500ri with snoot for background gradient.
