Shots from the new indoor rain machine

Rain machine, wow!

Love these! Any chance you can shoot 2nd curtain sync with your strobes to get the rain drops going down instead of up?

Actually, the effect looks like illumination decay of xenon flash. A full discharge can take many ms (milliseconds), starting with a short interval of highest lumen followed by a longer decay tail. Assuming a nominal discharge time of 1/1000s, the math says a falling object has speed of 6m/s after falling 2m, or 6mm/ms. At the scale of a water drop, 6mm of motion blur is easily discerned.

P.S. According to a Google search, the terminal velocity of large raindrops is 8mm/ms.

Then it seems like speedlites would be a better option to freeze the drops completely, since they don't have the tail burn that those strobes have

Mask the photo and flip the droplets over..

At full discharge, Speedlights have the same illumination decay as any xenon flash and the t0.1 rating is middling. At lower energy settings, the output curve is indeed chopped by IGBT but studio packs (whether IGBT or bank-switched) can deliver the same luminous energy at respectively lower energy settings where t0.1 can be 1/10,000s or shorter. A short t0.1 will freeze the raindrops entirely. For example, the Profoto Pro-10 in freeze mode at setting "5" will discharge 75J in 1/20,000s t0.5 IGBT. 75J is a full-energy discharge for a big Speedlight.

Of course, Bart may not want frozen raindrops.

That is an excellent explanation

All of these were shot with 2 - 12x60 gridded strip boxes...

Very nice work.

Test for a group shoot.

Leap of Fashion. Elinchrom strobes froze her at 1/4000 flash speed.

A little warm-up.
