Toronto. Well over a half century ago a young Latvian designed the amazing Minox spy camera. For a time, some models used a novel idea to add to the lens correction – the film plane was slightly curved along its longer side. A similar approach was taken with the Minox enlarger. Camera and enlarger were both used wide open (no aperture). I had the enlarger and two versions of the tiny camera with the curved film plane – the Model IIIs and the Model B.
Recently, Russ Forfar dropped me a note say that Science Daily in its Science News section on May 30th described how scientists had created a curved digital sensor. The curve allows a sharper lens when used wide open giving better resolution under low light situations. Shades of that old Minox spy camera! (Minox is still around today.)
