341 - QWERTY

From 365 Project
The QWERTY is the standard layout for English keyboards. The layout comes from the 1870's and was devised using a study of letter-pair frequency to position the letters to avoid type bar jams that plagued early typewriters. Originally the letter "R" and the period "." were reversed on the keyboard. They were switched into the current positions so a typewriter salesman could impress customers by quickly typing out "TYPEWRITER" using only the top row of letters. The photo is my Logitech illuminated keyboard, a fine device for working late at night. Canon Rebel XTi, 1/20s @ f/3.2, ISO 800, 50mm macro.

Thanks for the comments. They are much appreciated. Some days doing the write up is harder than taking the picture. But I'm a big fan of trivia and minutia and love sharing.
