Minimum W/s Studio light to freeze movement

[danielyamseng]

What's the mimimum studio light power to freeze the movement of a typical fashion shoots? I.e to freeze a moving subject who keep changing pose in a split second.

Power has nothing to do with it. Studio strobes freeze motion because of their short flash durations. Whatever the power, just shoot at max x-sync to minimize ambient light, and you should freeze them pretty well.

johnboy00, then is it a small power light has a lower max sync or the max sync is depend on the camera and not the light?

[alwaysonephotography]

max sync is determined by the camera.

Higher power settings on flash units tends to normally result in LONGER duration flashes...the flash output is increased like running a hose to fill a bucket, bigger bucket you run the hose longer! (There are a few flashes that do not operate in this manner, but typical ones do.)
