Hello steemit all.

The number of lens filter variants make different results on the image, that's for sure. With various functions can also help the lack of lens and camera functions such as muffle over the light during landscape, even the filter becomes a necessity for the landscaper to get good results, unlike the photographers portrait, they very rarely use filters.

Why use Filter? The filter is just like the benefits of sunglasses, to facilitate vision in a very bright glare. Filters also have the same function in photography that is to reduce the light coming into the lens and even improve the color, also reduce the reflection and protect the lens from damage.

Here is the various forms of lens filters.

Screw-on filter

This model includes UV / Clear / Haze Filter / Circular Polarizer, Neutral and color filter. This model also has different thickness, thick model can add vignetting while thinner reduce vignetting, but thin model can not be used to put lens cap.

Filter Square

This filter is another favorite choice for the landscaper, usually in direct grasp or using a special filter hook for easy shooting and can also join multiple filters if it is not enough to use a single filter. But it will have a negative effect for the image if in a few stacks of filters because it adds reflection.

Filter the rectangle

Although the square becomes a favorite, it seems there are still more favorite for the landscaper is a rectangular model, the reason for having a wider field and have more space to move up and down.

Drop-in filter

If this one is only used for large-sized lenses such as tele, and only available for Polarizer.

Which of these 4 forms do you use?
