World on a String
Stunning images of world map photographed through water droplet have been causing a lot of buzz lately (for example, Gizmodo, Mail Online, and Reddit). The images were taken by Markus Reugels, who is fascinated by the shapes simple wafer drops can form but too fast for human eyes to see.

You can click on the image below to see more stunning water droplet images taken by Markus. Alternatively you can also visit his gallery at 500px.

The following is an image of his setup. More setup images can be found in his Flickr set. The details on how he took the photo can be found at his website.

Refraction - Setup

In order to capture the amazing forms of water, very short burst of flash is needed. If you are interested you may want to read our posts: High Speed Photography at Very Slow Shutter Speed, and Flash Duration. Markus uses a Vivitar 285 and 1/16 power is the upper limit to capture sharp images without motion blur. 1/32 or 1/64 power will do better. Markus shots at f/16 to get the dpeth of field required. The shutter speed of the camera is not very important because the motion is frozen by the short flash duration not shutter speed.

To trigger the flash, a circuit with photoelectric sensor that can detect the water droplet and introduces a delay before firing the flash is used. There are multiple possibilities (English translation) listed on his website but it seems that he is using a custom-made device called Glimpsecatcher.
