Photography tips
How this image was taken
In this shot, the 2-second shutter speed creates the flowing effect of the water, while the small aperture of f/20 turns the light sources into distinctive starbursts. The ISO 6400 setting compensates for the low light levels at night.
- Use the shutter speed deliberately to render the water movement smoothly.
- Experiment with the aperture to create sharp light stars from street lamps using a high f-number.
- Select a wide focal length like 12 mm to capture a broad perspective of the nocturnal scenery.
