I’m often asked, “Should I use a Polarizer?” Like everything photographic, the answer lies in the light. Not the blue skies, but in the light. Now if you want to REMOVE the reflection of the skies from a subject like in this case, the side of this P-51B, then use, as you can see, the polarizer is the tool. Shot with the D5 / 105f1.4AFS at f/1.4, you can see the Kill Flags pop and not pop as the polarizer is rotated.
