A bright, sunny winters afternoon, a Fuji X-T2 and 18-135mm lens and a B+W 67mm Circular Polarizer and you have the recipe for some very punchy color!
I shot using RAW+JPG in Fuji Velvia Film Simulation Mode. The addition of the Polarizer has added to the saturation of the colors.
I shot these images as tests and I realize that technically I should have removed the polarizer for some (all) of these compositions. The effect of polarization in the sky is strongest at 90 degrees to the Sun position and null with the Sun in your front or your back. With a wide angle lens the sky can be unevenly polarized and look very ugly.
