The Guardian has posted an article on a new book called The Photographs Not Taken by Will Steacy. It's a collection of 62 stories from photographers about great images that they saw but, for one reason or another, didn't photograph. 

The reasons why the images were missed range from hesitation to ethical constraints to a supposed Jedi mind trick performed by a movie star on a would-be paparazzi. 

The Photographs Not Taken will be published later this month.
