Starting waterdrop photography can be an addictive past time.
Patience, Persistance, and Perseverence is required!
Each drop is different, but the collisions that can occur are amazing.

I am by no means an expert-just want to show what can be created,some even inside a bubble...so cool!!!
I am new to this type of photography, and invested in The Pluto Trigger-a versatile ,high speed smart camera trigger controlled by IPHONE or Android app via Bluetooth.
It is possible to shoot everything from lightning strikes, to waterdrops, to star trails etc. at a very economical price point.
