Shoot a Fast Lens at Dusk or Dawn
Take an f/1.2, f/1.4 or f/2 lens, and go out at dusk or just before dawn.
If you’re lucky enough to own the stellar Nikon D3 or Nikon D700, or similar camera, shoot at ISO 3200 on up and have some serious fun being creative with lights and shadows, lines and sky. City shooting can be very enjoyable this way. Other DSLRs should perform fine up to ISO 1600 or 3200; the D3/D700 are especially well suited to low light.
Use good technique for low shutter speed shooting: pin the camera against your shoulder and forehead, while supporting it with your left hand and gripping it with your right. More.
