How to Take Pictures of Water Using Long Exposures
By Bill Fortney
- Set the ISO to the lowest possible speed—usually ISO 200 or Low 1.0.
- Set the camera on A for Aperture Priority Automatic. Set the aperture to a small opening like f/22 or f/16—the camera will automatically set a shutter speed. The best shutter speeds seem to be between two and eight seconds
- Attach an electronic cable release so the camera can be fired without shaking the entire rig.
