London-based Reuters photographer Luke MacGregor shot the picture above by using a slow shutter speed, around 1/50th of a second, and continually shooting frames with no flash in the hope that he would catch the moment a flash from another photographer illuminated Jessica Biel posing on the red carpet.

This reminded me of an earlier red-carpet picture of Jessica Biel where Luke had used the same “catch flash” technique. The picture of her arrival at the BAFTAs, below, caused a mini stir of discontent amongst the desk editors in Singapore. Some editors championed the picture, others wanted to reject it, or ‘spike’ it in journalistic terminology. One editor even said the technique was like “shooting by accident”.

Luke himself says “I guess it is a little like shooting by accident – except that I have planned to shoot by accident and have thought through the situation to try and get what I want using some form of judgement”.
