A place to politely discuss the tools, technique and culture of photography.

This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.

Why my pictures are half black when I use a fast shutter with a flash trigger? (alien.top)

I faced this problem where I used a new flash trigger and after a couple of good photos, photos started appearing like this https://imgur.com/a/iNw4rkr then the camera stopped working for a while and when it did there were two lines following the f stops. so I tried the old trigger and had the same problem, after a while I realized that the shutter was 1/ 400 and 1/250, and when I slowed it to 1/100, no problem anymore.

The flash can only operate if the entire shutter is open for a moment. At shutter speeds above about 1/250 second, the second shutter curtain drops before the first is all the way at the bottom.

Your camera will list a shutter synch speed. That's the fastest you can shoot and fire a flash.
