In this recurring column, we highlight a few items we've run across that don't merit a full story of their own but are interesting enough to bring to your attention. This time we look at cool Hungarians, Lukas Korschan, Andy Woo, Blanton Museum marbles, motion, tomorrow's Worldwide Photo Walk and the non-Riemannian nature of perceptual color space.

  • The Associated Press presents images of Hungarians Struggling to Stay Cool in Budapest Heat Wave where air conditioning is not always available. Inflatable simming pools, fans, balconies, garden hoses and spray bottles are among the options, recalling long-ago summer vacations.
  • Lukas Korschan provides A Glimpse Into Our Transient Society in his new book Nowhere Anywhere Everywhere. "Korschan's publication dissects the concept of 'nonplaces' -- a term most often associated with the work of French anthropologist Marc AugĂ©, which refers to modern spaces of passing, lacking meaning and history, in which visitors do not experientially relate to in an intimate sense," writes Devid Gualandris.
  • Andy Woo captured An Osprey Gently Gliding Along the Water's Surface and Grace Ebert has it.
  • Kirk Tuck visits the Blanton Museum with his Leica SL2 and TTartisan 50mm f1.2 for some luscious black-and-whites of marble statues.
  • Jason Little lists Four Fun Ways to Show Motion in Your Photos. "There are times when a shot that dynamically conveys motion is all you want and you can achieve that by not keeping your camera still," he writes.
  • If you're goig to tomorrow's Worldwide Photo Walk, Scott Kelby has some last-minute advice for you.
  • And if you'd rather dive into The Non-Riemannian Nature of Perceptual Color Space, that can be arranged to. Say the authors:

For over 100 years, the scientific community has adhered to a paradigm, introduced by Riemann and furthered by Helmholtz and Schrodinger, where perceptual color space is a three-dimensional Riemannian space. This implies that the distance between two colors is the length of the shortest path that connects them. We show that a Riemannian metric overestimates the perception of large color differences because large color differences are perceived as less than the sum of small differences. This effect, called diminishing returns, cannot exist in a Riemannian geometry. Consequently, we need to adapt how we model color differences, as the current standard, Delta E, recognized by the International Commission for Weights and Measures, does not account for diminishing returns in color difference perception.

More to come! Meanwhile, here's a look back. And please support our efforts...
