On my recent trips I mostly shot with my Hoya HD Polarizer on. I always adjusted the angle of the filter to get the strongest effect and it always looked good in the viewfinder! Just awesome blue skies. Sadly I couldn’t check the result on the display, because it was too bright outside. Back home I imported my shots to the computer just to see that many of the shots are unusable, because the sky is horribly dark. It looked different through the viewfinder, which is related to the much lower dynamic range of the digital sensor compared to the eyes. (+ The Photo is underxposed)
It’s simply a handling error on my side. The effect of a polarization filter depends on the atmosphere and the angle to the reflecting surface. In the above image the sky was very clear and it seems like I shot in about an 90° angle to the sun. A simple rotation to lessen the strength of the polfilter, and the sky would look much more natural.
So, always check your results! I think I’ll get a Hoodman Hoodloupe for my camera…
