Photography tips
How this image was taken
The long shutter speed of 1 second combined with the small aperture of f/22 creates a smooth, flowing representation of the water at the Reuss weir. The 24 mm focal length allows for the integration of the Jesuit Church into the context of the old town.
- Use a small aperture like f/22 to extend the shutter speed for a long exposure, creating motion blur in the water.
- Choose a wide-angle focal length of 24 mm to capture both the weir in the foreground and the architecture of the Jesuit Church in the background.
- Maintain a low ISO value of 100 to ensure high image quality without noise in this shot.
