A few years ago I had written about Guillermo Luijk’s technique to remove completely noise from digital photos. We know that this is a difficult task, but his solution is relatively simple: Shot the scene in a correct exposure according to our usual workflow; Repeat the shot now reducing shutter speed by 4 f-stops that…
A few versions of this text editor (sometimes) loved by many software programmers / Archive of old Emacs versions.
