Learn how to freeze moving subjects in a long exposure photo by creating a composite of a long exposure shot and a high ISO fast exposure.
You will need two frames to work with in post production; one with a fast shutter speed to freeze the moving subjects, and one with a long exposure to smooth out the water in the scene. You don’t want to change the Depth of Field between the two frames, and need to make sure that the overall exposure remains the same, so you are left with changing the ISO setting to achieve the results you want.
The long exposure shot will be taken at ISO 100 and whatever settings will be required to get the optimal exposure for the scene in front of you and the faster shutter speed shot will be taken with a higher ISO setting allowing you to achieve a fast enough shutter speed to freeze the motion of the subject you want stationary.
In the example photograph the long exposure was taken at 1.3 seconds, and the high ISO photograph was shot at ISO 4000. This allowed me to get an exposure of 1/30th of a second (still fairly slow, but workable for the desired result).
Here’s the first, unprocessed image, straight out of camera. Before you get to freezing the moving subjects you need process the original photo.
Freeze framing moving subjects, has been done only a handful of times. Likely because it was either at the right moment and the person stood still or with the help of Photoshop. First off have your camera ready to take two different images, one with a fast speed to capture the moving subjects and the other with a long exposure to smooth out the surface of your landscape.
