Okay, gang. . . here's the dumb question of the month. What is the
practical difference between a circular and linear polarizer? Is there
a difference in the effect produced? The amount of light attenuated?
Both? Neither? What's the story. I've have not used a PL in a long
time (more than I care to admit) -- I need to buy a couple and want to
get the straight scoop.
Thanks!
