Camera filters are small circles of tinted glass which creates a huge difference in your images.
Filters have a variety of jobs: filters improve your pictures, filter out unwanted light, enhance colors, increase contrast, and protect your lens against dust, smears, and scratches.
In this post, I will go over the three most popular filters. The first filter is the UV filter, which is used in all styles of photography. This filter doesn’t affect the image quality. Instead, its purpose is to protect the lens from dust, dirt, and scratches. The original purpose of this lens was to block UV rays, but now that most lenses are able to block those rays, this filter is primarily for protection. Next, the Polarizing filter reduces reflections, cuts out haze, and enhances colors. The Polarizing filter is used in many areas of photography, though primarily landscape photography. Lastly, the Neutral Density filter is used in flash and landscape photography. This reduces the amount of light your camera’s sensor receives. This filter helps to avoid overexposure (photos that are too bright) and creates motion blur while maintaining good image quality.
Most filters, such as the UV, Polarizing, and Neutral Density, are circular and able to screw right on to the camera’s lens. Other filters, such as the Hard-Edge Neutral Density are rectangular, and require a filter holder. If you don’t have a filter holder, or you don’t want to purchase a filter holder, you can simply hold the filter in front of the camera’s lens.
Before you go out and purchase a variety of filters, decide what areas of photography you enjoy and the possible situations you may come across. By planning, you can focus on only the filters you need; this saves money and the hassle of carrying unwanted filters around.
