Why are polarizing filter results so inconsistent in landscape photography?

[Avery.J]

I’ve been trying to get a better handle on using a polarizing filter for landscape shots, specifically to cut reflections on water and deepen a blue sky. But my results are really inconsistent—sometimes the effect is dramatic and other times it barely does anything, even when I rotate the ring. I’m wondering if the angle I’m shooting relative to the sun is more critical than I realized.

I've found the effect is strongest when the sun is to the side of you and a bit behind the camera, not straight in front. On calm water you can notice the glare fade as you rotate the ring until the water looks glassy and the sky deepens. It can fade to nothing if the light angle isn't right or if the surface is choppy, so I don't count on it every time.

Mine feels inconsistent too. Some days the water glare vanishes and the sky pops, other days I barely notice a difference even with a big twist. I suspect the wind and surface texture matter as much as the angle.

Could the real problem be the water surface or the light direction you’re using to frame the shot, not the filter itself? I’ve worried about that and kept looping back to weather and timing.

Sometimes I drift off topic and think about other tricks, like using a graduated ND for balance or waiting for a moment when the water is mirror-smooth. Then I come back to the same question: is the tool really solving what I’m after here, or am I chasing a steady effect that doesn’t exist?
