To nudge the odds in your favor, follow these simple guidelines:
• Shoot from a tripod.
• Estimate your exposure, and adjust camera settings based on the results. A good starting point: 2 sec at f/5.6 and ISO 100 to suppress noise.
• Because long exposures drain batteries, charge yours fully beforehand and bring an extra.
• Standard and tele lenses produce more pleasing focus blur than wide-angles. Lenses with loose-turning focusing rings are preferable to those with stiff, overdamped focusing actions.
