The basics are very simple and well known for high-speed photos: a dark studio, camera shutter open and flashes with short flash duration to freeze the movement, triggered at an opportune moment. The colours come from colour filters in front of the flash lights. The 'wigs' are simply water-filled balloons either dropped on the models heads (sic!) or for the lengthy ones, oblong balloons that can be shaped and then are burst by an assistant with a needle.
Tim points out some important points to remember if you'd like to try this yourself:
- Make sure your equipment is splash-proof and have the model stand in some recipient for the water!
- Make your trials for the set-up with some non-living item, most models get impatient quite quickly with balloons being dropped on their head :-)
- Bald heads work best for this approach.
