Remember the days of film photography, when you’d get your prints back from the lab and the last image (or sometimes the first) would be hopelessly out of focus? There might be some bit of recognizable imagery with a smear of sprocket holes or part of the film itself laying across it. They had a lovely atmospheric quality that seemed to transcend the other snapshots they book-ended. The modern day equivalent might be those accidental shots when the focus goes awry or the shutter lags to the point where nothing recognizable manages to hit the sensor. Most people probably delete them immediately but I process them with the rest and treasure them like I did in the film days.
