Dazzle camouflage

Dazzle camouflage

Interesting article over on TwistedSifter about the use of so-called “dazzle” or “razzle-dazzle” camouflage beginning during WWI. (The Wikipedia article is pretty good, too.) It’s a kind of practical op-art: The idea was not so much to make the ship invisible against the background, but to confuse enemy weapons operators as to its distance and heading. The Rhode Island School of Design has a wonderful online collection of various paper plans for dazzle camouflage schemes donated by Maurice L. Freedman, who was district camoufleur for the 4th district of the U.S. Shipping Board, Emergency Fleet Corporation, and would go on to invent the board game “Battleship.”

“Photo grandpa” builds mother of all homebrew laser triggers

“Photo grandpa” builds mother of all homebrew laser triggers

A reader who saw Marc’s recent post about an Arduino-controlled laser photo trigger wrote in to tell us about the amazing work of Belgian photographer fotoopa (which, we hear, as “foto opa,” means something like “photo grandad” in Dutch). That’s him in the picture above, and that’s his awesome homebrew laser-triggered camera set up that he uses to capture amazing pictures of insects in flight and splashing drops of colored water. I’m generally skeptical of film purists, but fotoopa makes the compelling point that no digital camera has the shutter speed necessary to do this kind of imagery. He claims the Compur #1 shutter used in his 2008 setup has a speed of less than 5 milliseconds. Technical details about his 2009 setup are available here. [Thanks, Wilco Schillemans!]
