When you're taking a picture, you can't ignore the light - but the way the light influences the photograph depends on the qualities of the camera. When I took this photo of a small lagoon along the pedestrian path to Granville Island, from where I was standing the sunlight was reflecting off the water directly into the lens; the viewscreen was just a disorganized mess of light, but I figured I'd take the shot anyway to see if it turned out. It wasn't until I was on the bus and away from the bright sunlight that I was able to tell.
I wouldn't have been able to plan it this way, so I think it works out as a result. A good photo, I think, to be the first in my switch from general public domain licensing to Creative Commons BY-NC-SA licensing.
