Freezing motion explained
When freezing motion always remember that it’s not the shutterspeed that freezes the model, but the flash duration. Just make sure there is no available light in the studio.
You can check this by shooting an image without the strobe. If it’s almost black you’re fine.
Do realize that the choice of strobes is vital.
You need the fastest flash duration at half to full power. Strobes with insane flash durations that are located in the lower power settings are less effective.
Aim for at least a t.05 value of 1/2500 and preferably 1/3500 and up.
Aim for f11 or f16 to make sure you have enough dof. And now just time it 😉 and coach the model
Would be nice to see your shots.
