LONG exposure was the challenge for our Guardian Camera Club members this week.

We decided to opt for a technical, rather than a themed, challenge and we love the submissions from our group of talented photographers.

Long exposure is technique where you keep the shutter open for a longer period of time than normal.

This means instead of taking your photograph in a split second, you trigger the shutter button and then wait – sometimes for minutes or maybe even hours – until the exposure is finished.

Take a look through the gallery above!
