Minimum shutter speed with a speedlite (alien.top)

Hi there,

I have a what I thought would be a simple question, but can find a simple answer on Google.

Some friends will have a party for Halloween, half indoor, half outdoor. Ans they asked me to take some pictures, since I’m the photographer. The thing is, it’s not really the kind of photos I make. And I have a little knowledge about using flash.

So here’s my gear :

Canon R6ii
35mm 1.8
24mm 1.8
Godox V860

I’m a little familiar with the concept of ambient light using a flash, but here’s my question : If I don’t want to crank up my Iso for ambient light, how slow I can go with my shutter speed ? People will probably dance and drink, so without flash, with good light conditions, I would probably go between 1/250 and 1/500. But with a flash, considering that it’s supposed to freeze the subject, how slow can I set the shutter speed ?

Thanks for your help

Correct, I will just add few words. High speed sync uses more battery and is usually not that powerful. Some use them in opposite way, instead of nd filters, so in very sunny day, trying to get portrait with f/1.8 with 1/4000s. For halloween party I would not go for this settings, I would probably want to have some ambient lights involved, but froze the action with non hss. What is freezing the action is not the shutter speed. That works for continuous, ambient light. What freezes action is duration of the flash beeing burned. And these times are usually much much shorter, than sync speed, also depends on power of the flash. Full power burns usually longer, than 1/4 power. It may be 1/1000s vs 1/8000s. So. Turn off the flash first, expose for ambient light first. Then turn flash on and play with flash power. Now shutter speed and aputure will affect ambient light, aputure will also affect flash, but shutter speed will NOT affect flash. Have fun :)
