Car headlight fogbow

Car headlight fogbow by Michael Ellestad (atmospheric optics site). The shadows of the camera and tripod are visible on the track. The camera shadow marks the centre of the bow. The main fogbow is fringed with red on the outside. Inside it a well defined supernumerary has reversed colours - blue outside and red inside. Look outside the main bow to see a faint secondary fogbow produced by two internal reflections inside the fog droplets. More car fogbows. ©2004 Michael Ellestad, shown with permission.
