This is a double exposure. The shutter is open for 20 seconds. For the first 10 the subject holds a pose. Then they jump and held another pose. In this case the subject got too ambitious and fell over so there are actually three exposures. This was at night, after the sun had set over the Kalutara hills. The light you see on the plants is not visible to the naked eye. All we saw was dark. However, all that information is there, if you keep the shutter open long enough. I find it weird, ghostly, ethereal. Some of the lighting you get from long exposures is another world, neither day nor night. I’m used to cameras approximating what we see during the day, but it can exceed what we see at night, sometimes taking us to strange places.
These are a few older long exposures. Not double, just spooky
