“Small changes in light, such as from the sun going behind clouds, will be covered by your camera’s exposure, but as light drops or rises precipitously (as the sun goes up or down), slowly change the f-stop or shutter speed to follow the average metering for the scene as the sun moves. This will vary depending on how bright you want nighttime to look. You may, for example, want to have an extremely long shutter speed after the sun goes down to allow car lights to make a flowing stream of light, or for moonlight to make a valley look like strange daylight. For this, you might change your shutter speed from a 500th of a second to as much as a second, just over the course of an hour. To figure out the proper shutter speed and aperture, you could use a light meter, but often it’s just easier to use the the light meter built into a backup camera.
These changes in shutter speed or aperture will show up immediately on your exposures as one-stop differences from one frame to another. To smooth out this transition, you’ll use processing software.”
