Polarizing filters

You see, a large percentage of the light that we see objects is reflected light and that is the light that captures our camera. Polarizing filters serve basically to eliminate these specs, which leads them to saturate the colors to give you more experienced and higher-contrast images. But to understand this best thing is to show you some examples.
In this picture car that I share below (very common example filters polarizers) can appreciate the difference between a photograph with filter and another without filter. The difference, as you can see, is the glow given off by the car. Interesting difference no?

In this picture can notes r the same effect. Because the shiny surface reflects much of the light is especially evident with cars. On the second picture color is more shocking and more realistic, more sharp contrasts.

It is basically the polarizing filters have not much science and all they do is take your shines when you want to photograph outdoor. Also have the effect (as all filters) reduced the light that enters the camera, so it may be necessary to open semicircular aperture more of what you would normally when using a filter polarizer.
When it comes to buy a polarizing filter you must take several things into account. It is best that you buy one from a known as Canon or Nikonmanufacturer. Another factor that you should take into account is the diameter of your goal you must buy a filter that is of the same diameter, otherwise it will be your House. I speak of course of circular filters. If on the other hand you want to buy a porta-filtros then you should not worry about the diameter of the objective (fit and serve to accommodate filters of different diameters).

UV filters and protection filters

UV filters do not produce any appreciable effect on our photographs only prevents the entry of ultraviolet rays in our camera which means that the picture will be exactly equal.
Then, so I want one? The vast majority of photographers are purchased UV filters not so much the fact protect against ultraviolet rays of the Sun but rather as a protection for the lens of the camera. It is a filter quite cheap and in fact I have come to see many UV filters for the small fee of 8€.

There are also those who argue that a UV filter removes sharpness to the photographs but I have not personally noticed no change in photographs since I use a UV filter. I suppose it's a personal matter that must be overcome each. In any case it is a very reliable alternative in protecting your objective of scratches, dust, and other.
