I can't afford to be in on the purchase, but I wanted to tell you that your videos are awesome! Besides the footage, great job editing, too.

In Topic: YS-D1 Cutoff Issue

Thank you for the advice and I will test using 1/180 and see if I can prevent this in the future. Looking at the results, it makes a lot of sense to me. You can visualize where the curtain was closing when the strobe fired. Analyzing the situation, it does not make sense - why would it happen only 20% of the time with same shutter speed, and why would it never happen with the older strobe (ys-110a) on the same exact camera, lens, port, fiber cable, and camera settings? But the whole reason I ask the experts is that my analysis has failed me, so I'm glad to have a path to a solution!

Thanks for your response. This did occur to me, but I guess I assumed that if the shutter speed were to blame, it would manifest on all shots. The problem only showed up on about 20% of the shots using the macro setup described. It didn't manifest at all with my wide shots and 2 strobes (the same ys-d1 + my older ys-110a).


All the shots on which the problem occurred were using these settings:


M (manual exposure)

1/200 shutter

ISO 100

f8-f16 variable aperture


I did not alter the default flash settings in terms of 1st or 2nd curtain firing. The other 80% of the shots where this problem did not occur also used 1/200 shutter speed.
