I have seen many wonderful photos of water flowing, and wonder how the effect is achieved wherein there is the line or blurring effect. Is this in pre or post production
Hi Joe, welcome to NPN If I understand what you are asking the blur of flowing water is created in the camera by exposing with a long shutter speed. If the camera is on a tripod, and the rest of the scene is still, the water will be recorded as a smooth blur. The longer the SS the more blur effect there will be. The amount of effect varies greatly with taste. I often use 1/20 to 1/2 of a second. To achieve sharpness in the rest of the image your tripod should be sturdy, consider using mirror lock up and a cable release. If you dont have a cable release set the self timer to release the shutter without your pushing on it yourself.
Exactly what Ed said. Compose your image on a tripod and aim for a slow shutter speed (depending on the speed of flow - usually 1/8th of a second or slower).
Some people will use a neutral-density filter (not the graduated kind) to achieve slower shutter speeds in bright light situations but in most cases, simply stopping down to your lens' smallest aperture will do.
Spring is always a great time to find lots of water to shoot.
