I'm looking for information regarding LPS filters. Does it really work (for visual usage)? I know they come in many different sizes - 31mm (1.25"), 48mm, 60mm, 70mm. Why so many different sizes? Which ones, if any, are particularly desirable for visual usage? And yes, I'm a newbie living in southern California.
