Around The Horn
2 September 2015
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 (with more than 140 characters). This time we look at artifacts in Sony's Raw compression, the iPhhone 6S, Henge docks and a Denali double exposure.
- RawDigger's Iliah Borg and Alex Tutabalin discuss posterization in Sony cRAW/ARW2 files, showing how to detect artifacts caused by Sony's lossy compression (which is not optional) before analyzing Sony's cRAW format. A comparison with DNG can be found in the comments.
- Austin Mann speculates on What to Expect in the iPhhone 6S Camera as he prepares to review it at "an entirely new location" from his previous reviews in Iceland and Patagonia. He's expecting big things but not optical zoom.
- In Problem Solved, Kevin Raber finds a Henge dock to mate his MacBook Pro Retina laptop to his office monitor and keyboard. "This is a very clever design" he writes, "that allows me to drop my laptop into a dock and have all the connections made."
- Harold Davis recalls his 1980s-era poster Denali, the Great One as the mountain reverts to its Alaska native name. It was a double exposure to reposition the moon. "The landscape of Denali was photographed with a 35mm lens," he confesses, "I moved the camera, and photographed the moon on the same piece of film using a 200mm lens." But it was the mosquitoes that got him.
