Hello,
Im a beginner at this, and was advised to put a circular polarizer onto my lenses to get a better punch in color and to avoid the reflections from some surfaces. They also told me to "be careful when using telephoto and/or wide angle" because its going to break. Is that true?
Is there a specific way to use a polarizer? (does it come with a manual?) |

Yea polarizers work great for out door stuff, even some in door shots as well. I've never hear of it "breaking" if you put it on a telephoto or w/a lens? I've used mine on my 55-200 all the way out with no problems...but not every lens is the same I suppose.
Put it on your lens, turn it to adjust it to the color tones you want and shoot, shoot, shoot man!

The problem with polarizers and really wide angle lenses is that the poloarizer will darken a blue sky in a non-uniform manner, and it can look funky. The sky darkening effect is at a maximum in a direction 90 degrees from the position of the sun, and nearly zero at 0 and 180 degrees from the sun.
Polarizers effectively cancel reflections from non-metallic surfaces, but do not affect reflections off of metal surfaces. Has to do with the physics of the metal surface on an atomic level. Reflections are most strongly cancelled at a reflection angle of just over 30 degrees (shooting angle vs. the plane of the surface). The cancellation will be poor at very small angles.
Polarizers enhance color by reducing surface reflection that hides the true color of the object. In some cases, they can have an undesirable effect. If you shoot a portrait with a polarizer, the effect on skin and hair can be downright ugly; it gives both a very flat, non-reflective look that is quite unnatrual.
