The 2nd posting during lockdown. This Spectacled caiman was taken at night using a torch to find and focus on the subject and then a single flashgun on the camera. I have tried it with ducks since, but not got the same weird effect. The caiman are not dangerous and during the day you can get close without spooking them or feeling threatened, but during the night I did find them more intimidating. They were quite active and moving about on the water more than during the day.
