When it comes to photography, there are a few tools that can make a huge difference in the quality of your images. One of these tools is the polarizing filter. But is it really necessary?A polarizer reduces the amount of light entering the lens. This can be beneficial in certain situations, such as when shooting in bright sunlight or when trying to reduce reflections and glare.
However, it won't be of much help in low-light scenarios, as you'll need as much light as possible to photograph quickly. The use of a polarization filter in this situation is also questionable. You can't have a perceptible polarization when the light comes from behind, except to eliminate a rainbow, of course. There is also no need to use a polarizing filter for sunsets. It won't do any harm, so it's possible to leave the filter in the lens.
But watch out for strong sunlight, as it can produce additional flashes because of the extra glass in front of the lens. Polarizing filters provide a means to reduce glare, improve contrast and eliminate reflections in photos. Since these unique advantages can't be found with any other lens filter, polarizers are worthwhile for any type of photography. They are especially useful when taking pictures of water or through a window. The only reasonable solution in this case is to learn how to use the filter well, experiment and then draw your own conclusions. Whether it's protecting the lens, reducing glare, improving contrast, or capturing a long exposure effect, each type of lens filter offers something unique to your photography. In addition, you can learn more about polarizers and their effects in this comprehensive guide to polarizers in photography.
ND filters are normally used to compensate for excess light in the middle of the day or at dusk. Circular polarizing filters aren't the cheapest, but I highly recommend that you spend the extra money and invest in a quality option. Ghosting and double reflections are a problem with any type of filter, as light can end up reflecting inside the lens filter. Similarly, photographing in direct sunlight can cause similar ghosting problems, as light can reflect off the inside of the filter. In short, a polarizer works to eliminate reflected light from your photos, helping to improve the color and contrast of the image. So if you're looking for an easy way to enhance your photos without having to do any post-processing work, investing in a good quality polarizing filter is definitely worth considering.
