Your PL is probably a linear type.
To use a polarizing filter, you rotate it while looking through
the viewfinder to get the best effect - they work best at a angle

Thanks, Brian. Yeah, I bought the PL filter to use with my K1000
years ago. And thanks for the pointers on using it.
The PL is almost certainly a linear polarizer (Polarizer, Linear).
It should work with a digital camera as a polarizer, but might make
auto-focus problematic. For auto-focus cameras the Circular Polarizer
(CP) is recommended.
