There are no colours as intense as those found in nature, and there are no patterns or textures as complex and chaotic as those in nature. The deep red innards of this cactus apple are a prime example of both. The detail of that flesh is mesmerising, and that makes this photo both appetising (cactus apples can be very tasty), and hypnotic. The plain white background highlights the effect.
Images of cars speeding by as mere streaks of light during long night-time exposures never seem to get old. They add a sense of speed and activity to boring city shots, and the streaks of the red brake lights add a rich colour that brightens them. Here the effect is higtened because all we see is the lights and the road and what surrounds it is only implied by this almost abstract pattern.
