Bright colors and straight lines can make simple, but fascinating, photo. Take Noe’s picture above. The framing lines of the windows, the plywood wall, the bus stop, even the traffic lines in the street, all make your eye go from side to side, and up and down, to explore the picture. And while your eye wonders, it is delighted with fascinating hues of purple, yellow, and maroon, to just name three (there are more). And then, as an added bonus, the people are there to give the scene scale; what at first looks like a small building/block becomes much larger once you notice the people. Truly a great shot!
