Circular Polarizer

<< < (2/2)

JR:
I agree the loss of 1-2 stops can be costly in shutter speed or ISO performance in some situation.  Originally I had started to shoot with circular polarizing filter whenever I shoot outside in the sun.  I since then dialed back on their use to only use them in some situation, mostly for landscape or when I dont need to "freeze" the action.

With the polarizing filter on, I missed several shots where I needed to a higher shutter speed...They are a good tool, but I would not recommend them on all the time.

This was my thought.  I would put the clear filter on the lens for protection and only attach the polarizer when you need it.  A polarizer is helpful in lessening glare, enhancing shadows in flat light, and boosting color saturation.   As noted, the polarizer will block some light so it's best used only as needed.

personally the only use for a clear filter would be front element protection... Mostly because that said front element is neither cheap nor easy to replace. A CPL isn't that cheap, sure, but its not gonna cost a bomb to replace either. The image degradation from the additional filter just isn't worth it... and if you really wanted to protect the filter, take it off when its not needed?

Personally I only ever take out the CPL when I want to reduce reflections... or use the lights in the sky. Even then... not always.

Its just not worth it staying on the glass long term.
