PL
Polarizing filters are generally used in landscape photography, as they can both control polarized light – commonly known as "light reflection" and contrast. There are two types of polarizing filters: PL (Polarized Light) and C-PL (Circular Polarized Light), but C-PL filters are generally the most used.

STAR
By star-shaping light sparkling from light sources like holiday illuminations or water surfaces, star filters can confer your photos a more scenic and impressive effect. In the same way as for C-PL filters, star filters come in a two-filters rotating structure that, by rotating the filter’s frame, allows adjusting the angle of the light rays hitting the filter's surface.

CLOSE-UP
Also known as close-up lenses, close-up filters prove to be convenient filters to have at hand. By installing these filters on whatever lens you are using at the moment, you can easily but effectively shoot macro. Or, by installing them on your macro lens, you can further shorten the working distance and get closer to your shooting object, thus making it look bigger on the final image.
