A Delicate Waterdrop Umbrella

This is our entry in Lens-Artists Weekly Photo Challenge #46 – Delicate.

Colliding waterdrops create a delicate umbrella — here for a brief instant, then gone forever.   The photo below was created using our tripod-mounted Canon 50D and an ancient 100 mm macro lens in front of a paper background. The shutter was opened for two seconds while two drops of water were released into a martini glass filled with water. A flash, perpendicular to the camera, was triggered when the waterdrops collided. It illuminated the scene for 1/8000 of a second.  In the “umbrella” shape seen in the photo, the “shaft” is created as the first drop plunges into the water in the glass and then rebounds into the air. The “canopy” is created when the second drop collides with the rebounding first drop. (Technical note: It doesn’t really matter how long the shutter remains open as long as an image taken without the flash is black).

Canon 50D, ISO 100, f/22, 2.0 sec, 100 mm.

 

Dwon or Up — Cee’s Which Way Photo Challenge — February 16, 2018

This is our entry in Cee’s Which Way Photo Challenge — February 16, 2018.

When we first saw this umbrella stand, which supports a square umbrella at least 20 feet across, we wondered how the umbrella was lowered for bad weather. This morning we discovered the opening for the crank mechanism.  Turn clockwise for dwon, counterclockwise for up.
