Is it better to be good or to be lucky? How about a bit of both? Vincent Laforet was shooting a time-lapse of clouds over an Italian beach when a rainbow decided to line itself up squarely within the window in front of the camera. I’ve tried to capture rainbows before and can say it’s difficult because they’re usually very faint.
It’s also fortunate he wasn’t using a polarizing filter as these dramatically reduce rainbows’ intensity. Here are a couple of photos I took of a rainbow from the Golden Gate Bridge. The left uses a polarizing filter and the right doesn’t. These photos were taken seconds apart. Also check out the way the filter affects the reflections off the water.
