>> Mudlarkers come into the Thames when the tide is low and scour the banks for historical treasure. I'm Neil Hall, and I take pictures for the UK desk of Reuters. Many of the mudlarkers are licensed by the Port of London Authority. And it means they can use metal detectors and dig holes in the ground, take the objects away.
I enjoy covering news features in London because London is one of the greatest cities in the world, and it is really nice to put together a feature that reflected 2000 years of history that is in the city. Many of the mudlarkers choose to work at night because this is when the tide is at its lowest.
It's also very quiet. For me, this meant it was a bit of a technical challenge. I shot a little bit at twilight the best that I could. This meant I could get the ambient light from the sky. But as it got really, really dark, there's not much illumination at Thames.
So occasionally I would need a bit of off-camera flash, which I triggered remotely, just to fill in some of the details on the frames, so as to pick up persons and the people that were working.
