Fluid Photography: Foam, Ice, Air, Flood

  • From Russia with Foam: John Peterson passed along this gallery showing the hiterto unknown art of drawing on top of coffee. (I think Jerry Uelsmann might dig this one. ;-)) And later I found a video of the techniques in action.
  • Only slightly more permanent, the sparkling sculptures in the Harbin international ice and snow festival are built to chill. [Via] China Daily features photos from the opening ceremonies.
  • Elsewhere in cold China, check out this frozen waterfall. [Via]
  • The Musée d’Orsay features the work of Etienne-Jules Marey, who did pioneering work photographing air at the start of the 20th century, using imaging plus one of the first wind tunnels to reveal previously unseen details of air’s fluid dynamics. [Via]
  • Whereas those vintage photos are presented in frustatingly small form, the Paris School of Mines features large images of the city during the 1910 flood [Via]

3D printing becomes more ubiquitous

Wow: When an object shows up at Sears, you know it’s getting kind of mainstream–especially when it’s priced in the range of a decent laptop.  The company is now selling the CompuCarve Woodworking Machine, an $1800 device for "printing" 3D designs in wood. [Via]   Elsewhere, John Dowdell links to Bathsheba Grossman’s lovely metal sculptures, created using "a metallic deposition printer with laser binding before the final baking and a bath in molten bronze."  And AKI International offers laser-cut 3D mannequins and packaging. [For more on 3D input & scuplture, see previous entries.]

Decoding scrambled pixels

Removing data from a digital file is sometimes easier said than done. Redacting PDFs has sometimes proven tricky (something the Acrobat team has worked to address), and now a research report notes methods for unscrambling numbers or text that have been obscured via simple Photoshop tricks. [Via]

I asked a few Photoshop engieneers for comments & got some useful nuggets:

  • Gregg Wilensky says, "The ability to recover text that is blurred is limited by the amount of
    noise in the image (and knowledge of the blurring function). So, adding
    a bunch of noise to the image is better, but still not foolproof. I
    would suggest completely replacing the text with noise and blurring that
    (for aesthetics)."
  • Jerry Harris notes, "Having a known set of limited targets, OCR numbers in his example, makes the
    reconstruction task a bit more realistic in terms of useful results than
    most."
  • And Todor Georgiev writes, "Using a known set of blur kernels (those in Photoshop!),
    and a known set of targets, limits the set of possible outcomes
    and makes this technique work. But slightly change lighting
    and/or use custom blur filter, and your data is safe."

Come say hey at Macworld, Apple Store this week

If you’ll be in San Francisco this week, we’d love to see you at the Adobe booth at Macworld (starting tomorrow).  I’ll be booth-babing Thursday and Friday afternoons 1-4pm ("Does this tradeshow shirt make my app look big?"), and on Wednesday afternoon from 3-4pm I’ll be presenting the Photoshop CS3 beta at the Apple Store in SF.  I’ll be joined by InDesign PM Chad Siegel, who just may have some Intel-native page-layout kickassery to show.  (Okay, it’s more than "may.")  Hope to see you one place or the other.

[Update: Whether at home or in person, you can play the Macworld Drinking Game.]
