Circular Polarizer - Quick Test: K&F Concept Nano-C HMC

Initial test for a newly bought K&F Concept Nano-C circular polarizer. 

The first image has the polarizer set to minimize the reflection and glare from the flower and leaves. 

The second image has the polarizer rotated 90 degrees. 

The light was harsh and directional.

To me, the polarizer did reduce the glare and reflections from the flower and leaves, particularly visible in the second image.

The first image, however, looks a little flat to me.

The polarizer works, but shooting these hibiscus flowers under better lighting conditions, i.e., even and less directional, would do wonders.

Handling of reflections from water or glass would be an interesting next test.
