When good pictures turn bad

February 6, 2008 JimK Leave a Comment

There comes a time in when nearly every photographer decides some once-loved old work is crap. Edward Weston scraped the emulsion of some of his old glass negatives and turned them into window panes. He’d moved on, and considered the early work an embarrassment. I’m sure many pictorialists who saw the f/64 light felt the… [Read More]
