Components of a Drip Photography System


There's room for much creativity and ingenuity in setting up a system for drip photography. However, there are certain components to include. We've divided them into two lists with notes on each. provides the components on the left with the exception of wireless components. The photographer/experimenter provides the components on the right.


We provide Electrical & Electronic Components You provide Physical & Photographic Components
Component Description Component Description

AstroSplash Drop Controller

with 12VDC power supply

The drop controller actuates one or more solenoid valves in a timed sequence in order to release a train of 1 to 3 drops. The drop controller may also be used to open the camera shutter.

Water reservoirs

A reservoir, typically a Mariotte bottle, is used as the fluid supply, and a bowl or tray is needed for the target reservoir.
Solenoid valve with cable and pipe fittings 1 to 3 valves may be controlled simultaneously with the AstroSplash. Adapters are used to connect the valve to the fluid supply. The fluid drip is released from a nozzle.


A minimum of one flash unit is required, but at least two would be used for creative lighting effects. Backlighting is typically used with the light being diffused by a frosted plastic sheet. Colored filters provide creative lighting.

Photogate and delay timer

Any of the Multi-Trigger 3+ (MT3+), Multi-Trigger 3 (MT3i), Multi-Trigger 2 (MT2), or Delay Timer 2 (DU2) can serve as delay timer. (If you use the Delay Timer 2, you'll also need the Photo Gate 2i (PG2i). The interrupter-style photogate sensor is used to detect the passage of a drop, and the delay circuit generates the time interval before the flash is discharged.

Camera and lens

A digital SLR is recommended both for precise framing of the subject and immediate image review. A lens of at least 100mm focal length will allow the camera to be placed a good working distance from the splash site.
Cables for flash and camera

The flash units may be connected to the MT2/3/3+ or DU2 with cables. For 2 flash units, a cable splitter may be used. Alternatively, the MT2/3/3+ or DU2 can trigger a wireless controller for the flash units. ( doesn't provide wireless controllers.)

If the camera is to be triggered automatically, then a remote shutter cable is required.

Scaffolding A framework is required for all the components. Supports are needed for flash, camera, and lighting accessories.
