On an overcast day, the opportunity for above average photography actually rises. Say what?
We were on the Tagaytay rim on a cloud-filled day that drizzled on and off. It wasn't the best time for sight-seeing as the fog obscured the landscape and dark clouds above kept the sun from shining through. But in a place where the wind was always on the move, the light can change very quickly. I spotted a moving splotch of light on the lake and immediately pulled-over to wait it out. Eventually, the clouds thinned-out to allow shafts of sunlight to punch through. The result was Taal Lake lit in a most unusual manner. Enjoy.
(Pixel-peepers: A cloudy sky normally means very even lighting, so even that shooting on auto should be fine. But when photographing shafts of light, you need to under-expose your shot, sometimes by up to 2 stops, because those shafts are very bright, and because you want to capture the mood you remember.)
