Say the polarizer
The polarizer seems to have rarely mention this noun after we use the digital camera. Due to price problems - this very practical factor - digital SLR is not well popular, then, is it difficult to use the polarizer in the traditional SLR lens? I am afraid it is not. Canon's short-selling digital SLR is at least let us have some hope for digital orders. For those DCs that imitate SLR or even portable DCs, we have the same way to use traditional polarizers to meet our discerning requirements for the picture. "Old bird" in the digital field with smoke on the traditional battlefield is naturally a variety of color filter including polarization. However, for the first-time players, the number of players, there is a need to spread the knowledge of polarizations. First of all, I have to dare to be bad, and I will suffice, I'm, my sputum, my sputum, my sputum, I am, my horses, I am, my horses, I am, my horses.

Oh, pure theory thing, if it is not a class, I must be dizzy! Then I don't know some: The reflected light of the glass makes us not shooting things inside the glass window, the reflected light of the water makes us not shooting the fish in the water, the reflected light of the leaves of the leaves make the leaves turn into white, these phenomena Yuan is full of polarized light. The blue sky of the clear sky is also polarized in a vertical direction of 90 degrees with the solar direction, which makes the blue sky are not so deep. If these polarized lights are eliminated, many photos will appear to be more saturated, and the picture is clearer.
The related pictures of this topic are as follows: As the current digital camera market is rich, the DC of the imitation is coming, the DC of the mandarin is coming out, and the price below 10,000 yuan is also coming. In this way, some conventional color filters with quite useful value have come to "ready to move". However, DC has its own characteristics of its own automation, nor all of the polarizers can be applied. In a polarizing mirror, two types are divided into linear polarizers (PL mirrors) and circular polarizers (CPL mirrors). The related pictures of this topic are as follows: Linear polarization mirrors are the most common polarizers, but this most common polarizer is a digital camera that cannot be combined with high degree of automation. Because the current digital cameras have auto-focus and automatic exposure features, the part of the light information required for these automatic functions will be filtered by the line-type polarization, resulting in aeration that AE may not be allowed. AF may fail. In this case, a circular polarizer (CPL mirror) is used. The circularly polarizing mirror can be constructed of two parts: the previous portion is a conventional linear polarizer, which is capable of filtering out polarized light in a certain vibration direction. The latter portion can rotate in a circle through its polarized light vibration direction. This special polarized light is called a circular polarized light, and the circular polarizer is also named. Circular polarized light is nothing distinguished from the non-polarized light for most optical components, so the circular polarization mirror can be used on any camera.

From the above-mentioned group of comparison, there is no strong reflection on the window glass when the polarization is used, and the reflector is basically eliminated after using a polarizer.
Of course, the polarizer is not universal. If the sun is inappropriate, the glare of the non-metal surface reflection may be small in polarization. For example, shooting leaves often do not eliminate all reflections. If you use a super wide-angle lens, it is difficult to achieve consistent results in the screen. Especially when shooting the sky, it is very dark to compress the direction of 90 degrees with the sun corner, while the other direction is almost no effect, causing the sky color and brightness uneven. When shooting the water, some water surfaces do not reflect, and the other part is very reflective. Due to the rotating portion, the polarization is large, the thickness of the lens is large, and it is possible to have a sharp angle on the super wide-angle lens. It is recommended to use a ultra-thin polarizer (of course, the price will "spicy hands"). Also note: When using a polarizer, it is not advisable to use a hood because it is necessary to rotate the filter; the camera should be taken in the shadow.
There is also a question: What should I do if the lens of a digital camera in my hand does not add an additional mirror? In fact, this problem is also well resolved. As long as there is a diameter of a diameter larger than the camera lens caliber, adjust the angle when using it, it is possible to put it before the lens. Although it is a bit trouble, this method is very effective, and the trouble and cost of modification is saved!
