Mike Chan is a talented designer and photographer, but he took this wonderful angel photograph by being in the right spot at the right time.  Though he attributes the effect as being due to leakage of light onto the film, it still makes one wonder, "Could Mike have possibly captured the angels who were there to aid the fallen man?"  Here is Mike's own story:
"One day I saw an old man fall down just in front of the hospital main entry, when I walked along the street. Then I saw a few 'White Angels' run out to help that old man immediately, and I had a chance to take a photo of that scene. Coincidentally, the lighting effect was due to light-leakage onto my film.  However, the result was very good! Just like a light shining coming down from paradise! "
