Fill your tray with water and add the background behind.
First of all, set up your backdrop and tray. The backdrop can be anything but colourful paper works perfectly. We've used gift wrap here.
Add your tray or dish and fill it to the rim with water.
Create your water dropper
Suspend a plastic cup over the tray you've just set up. We've used a tripod and a load of gaffers tape to hold the cup in place. Next, pierce a small hole in the bottom of the cup with a drawing pin.
Set the camera on the tripod
Place the camera securely on a tripod and compose your shot. Pointing down on the tray can give a better perspective and using a macro lens will help you get close to the action.
Set the camera
Set the camera to manual exposure and manual focus. Set the shutter speed to the camera's sync speed (usually around 1/125 or 1/250), set a moderate aperture (f/11 works well) and set the ISO to get a good exposure with your flash.
Set up the flash
If you’re using an external flash, set it to a low power and point it at your backdrop. If you’re using the cameras built in flash, pop it up now. We've used a flash with a built in radio receiver and it's transmitter to make adjusting the power extra easy.
Start the water drops and focus the camera
Start the drops by adding water to the cup. If the drops don’t start falling straight away, give the cup a tap by the hole to kick things off.
Once you have a steady stream of water drops, hold a pen or pencil at the point the drops are landing and manually focus on the tip. This is much easier to focus on than the drops in motion.
Connect your sensor
Connect your Triggertrap Mobile kit to your cameras cable release port. Plug the other end into the headphone jack on your iOS device. If you're not sure how to set Triggertrap Mobile up, check out our tutorial here.
Set up the Triggertrap Mobile app
Set up your iOS device so that the camera is pointing at the base of the drop cup. We used a Lolipod combined with the Triggertrap Phonetrap to hold the iPhone in the correct position.
Next set the sensitivity on the app so that the camera fires as the water drops fall from the cup.
Add a reset delay
To stop the camera firing too often, set a reset delay on the mobile app.
