Scenario; you are in a busy city and want to capture the lights, but not car headlights or thousands of blurry people. You want a high definition noiseless image of a city night scene.
Long exposure is out because of headlights; so I thought what would happen if I took a lot of short exposure images and stacked them in an averaging way.
So I did a google search and cannot find if this has been done or even if it will work. The reasoning behind it is if something moves then it may look a little like noise to a stacking program like PSE10.
But how long the interval and how many images? Cheers
