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 the Louvre Abu Dhabi, Best Individual Focus MTF curves, a timelapse with a broken lens, Bokehmarket, the Camera app's new floor crosshair feature and QR codes.

  • In The Opening of the Louvre Abu Dhabi, Alan Taylor presents 24 photos of the new museum, which sports a 7,500-ton lattice dome that looks good from any angle.
  • Roger Cicala provides today's lens lesson in Testing Lenses: Best Individual Focus MTF Curves. Best Individual Focus? That's "how far from the center can you focus and get near-center sharpness at that point." No one's ever measured it before.
  • In How Long Must Eye Wait?, Harold Davis takes a timelapse at night with his Nikkor 16mm f2.8. So what? Well, it was blown over a few days earlier, cracking the front element and jamming focus at infinity. There were more problems but he managed to get 141 exposures he stacked in Photoshop. Ah, now you're interested.
  • Bokehmarket, in beta now, hopes to provide "nearly exhaustive snapshot of the current used and new market." You'll be able to set alerts for products you're shopping for, too.
  • You can thank Caroline Hermas for the floor crosshair feature in the iOS 11 Camera app. Point your camera to the flooor and crosshairs will appear if you have Grid enabled in the Camera app settings.
  • And, as Glenn Fleishman points out in Practical Ways to Use QR Codes, the iOS 11 Camera app also recognizes QR codes. Fleishman suggest a number of interesting applications for the familiar 2D technology.
