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 unusual pictures, autoimmune encephalitis, sharpness vs. aliasing, digicams and an anniversary.
- Reuters showcases nine images in The Week in Unusual Pictures.
- David Goldman illustrstes Christy Morrill's Year of Unraveling from autoimmune encephalitis using a variety of creative camera techniques.
- Jim Kasson discusses Sharpness and Aliasing, One More Time. "Sharpness is measured as contrast transfer at a particular frequency. Aliasing is what happens when the system tries to reconstruct frequencies it cannot sample," he writes.
- In Digicams: The Cameras of the Modern Digital Rebellion, Alberto Lima asks "several digicam enthusiasts, spanning the spectrum from influencers and community managers to hobbyists and asked them why they had opted for the lo-fi digital camera option."
- In Black Friday and TOP Is 20!, Mike Johnston celebrates the site's two decades with a plea to buy yourself a present (through his links, of course). We extend our outright standing applause to his past efforts and best wishes for continuing ones.
More to come! Meanwhile, please support our efforts...
