It was a well-attended meeting for Antony this week.  He is a commercial and fine art photographer, tutor and speaker, specialising in architectural and urban images using long exposure techniques. He has won many awards and is particularly known for his vivid architectural images and his unique perspectives on cities ranging from New York to London. He explored in depth the situations which require long exposure - firstly when there is low light, and secondly for creative effect, as with the image above.  His mantra was 'carry a [lightweight] tripod at all times' and throughout the talk he generously gave excellent tips on handling the light and getting the right colour balance, in any given situation.  His work has been commissioned by Toyota US and Sky Atlantic, and published by the BBC, Guardian, Times, and Ecologist.  Please visit his website  Anthony Zacharias  and consider one of several books he currently has available.
