Seeing Red

Figure 1 (No Filter) shows the original unaltered scene. The other images were all made using a circular polarizer; this deepens the sky and increases color saturation. Figure 2 (Circular Polarizer) shows this effect alone. Figure 3 (Red Enhancer + Circular Polarizer) additionally intensifies the red of the building. Figure 4 (Green Enhancer + Circular Polarizer) diminishes the red, but makes the green foliage really stand out.

The subject was chosen to simply show some of the basic abilities of these filters. With the autumn season upon us, there are many more interesting opportunities out there to “see red.”
