With extended exposure times and full manual controls, it’s possible to take some mesmerising low light shots that paint with light.
Instead of simply using the extended exposure to make a brighter picture, you can make light trails and create patterns with either the light of the scenery or an object such as a torch, lit metal wool, LED on string etc.
I’ve been trying out stuff like this since my ancient Fuji Z10. The Nokia N900 was used in a project to capture light emitted from a ‘spray can’. It’s cool to finally see that on the likes of the 1020/1520 (though with a 4 second limit).
NokConv has a great article showing some stunning light painting.
