Why filter? The essential UV filter to protect the front lens of the objective and not affect the picture quality. The circular polarizing filter for pictures with marked contrasts and eliminate reflections off water for example The fluorescent filter is the least useful of the three because it is useful only inside under fluorescent lighting to reduce green dominant resulting from this type of lighting. Do not use outdoors because the pictures have a purple color dominance. Finally a good quality / price ratio for these filters to book but to fans in photos.
