The best polarizing filters are designed to help you make the most of your landscape shots, thus allowing you to cut down reflections and give contrast and colors a notable boost. Here are a few tips you should consider before you buy a polarizer filter.
What is a polarizer?
A polarizer helps filter light into one single plane, which helps cut down reflections in your photographs.
Types of polarizing filters
There are two major types of polarizing filters out there, and they both serve the same purpose of cutting down the polarizing light that gets to your sensor. However, they both have different effects and are only compatible with specific cameras.
· Linear Polarizing Filters
Linear polarizing filters are designed to selectively allow plane light to pass through the camera through a specific orientation. You may only use this type of polarizer to allow vertical light in, or you may turn it 90 degrees to allow the entrance of horizontally polarized light. This is the perfect option for those shooting via water to capture specific details or marine life and rocks.
The reason for this is that water and glass reflect light in a straight line and more intensely. What this means is that as you adjust the filter, it will eliminate every reflected linear light.
· Circular polarizing filters
This filter accomplishes its function by using two distinct elements, which are the linear polarizer and the quarter-wave plate. Usually, the water wave is connected to the back of the linear polarizer, and when it is adjusted, it allows the light going through to be polarized circularly.
Note that such filters may be used with almost any DSLR lens rig, and they usually do not lead to metering errors associated with using the linear filters.
Key features to consider before buying a polarizer filter
Here are a few things you must never forget in your search for the best polarizer filters out there.
1. Go for slim frames
Slim frames will help you achieve the maximum level of versatility when you are out shooting. When working with wide lenses, thick mounts can be a challenge.
2. Color control
Getting cheaper filters can cause color cast on your images which is not the best thing. The good news is that it isn’t too much to worry about because slight tints can be corrected easily during the post-processing stage.
3. Lightening
Those who intend to shoot without a tripod should maintain an eye on the shutter speed while you use the polarizer. The reason for this is that the polarizers will help restrict about two stops of light. But the best quality polarizers will usually use higher transmission glass which cuts down this adverse effect.
4. Clearer images
Although you may use your polarizer close to water, you should be careful that none of the water will find itself in the filter. You could, however, get perfect filters that come with antistatic and hydrophobic coatings, which help keep the filter in shape.
5. Value proposition
One of the challenges of owning different lenses is that they are usually of varying filter thread diameters. But this does not mean that you need to buy the same polarizer severally to fit other glass pieces. Purchase one that fits your lens with the most oversized filter thread diameter, and then you may use step-up rings to have it mounted to the others.
6. Glass quality
Filters are made using glass, and although glass means better image quality, using low-quality glass can adversely affect the quality of your images. With glass, it isn't easy to know the quality except you use it in the field. The underlining factor here is that you get the quality you pay for ultimately. Be aware that some filters are made with coatings, and such layers have different uses, including maintaining contrast, cutting down glare, and averting scratches.
7. Quality of the glass
Filter threads are generally made using metal, and weaker metals usually are susceptible to being broken. Low-quality filters are produced with aluminum which can be bent, and this causes dents. The premium quality filters are made using brass which can withstand abuse and is generally more robust.
Tips for using a polarizing filter
Polarizing filters blend two glasses that are fixed together, with the front piece rotating while the other does not. By turning the front of the filter, you will cause a change in the reflection's intensity. Note that while shooting using a polarizer filter, you begin by rotating the front filter and observing the effect changes. Also, the reflection will become apparent, and colors become less or more saturated. Ensure to search the position which adequately captures the image effect you desire. You could opt to eliminate reflections or enhance them as the case may be.
However, be mindful of the fact that polarizing filters help impede light at a particular angle. The sun’s position will determine the functionality of the filters. Usually, you get the best effect from your polarizing filters when the sun is at an angle of about thirty-seven degrees.
FAQs
Q. How can I optimize the intensity of my polarizer effect?
A. By changing the position of the filter, you will be able to adjust the intensity of the polarizer's effect. If you want the best effect, you should point the lens 90 degrees away from the rays of the sun. The most innovative way to do this is to tell your index finger at the sun with your thumb up.
Q. Should I be worried when using my polarizer on a wide-angle lens?
A. Yes, you should be careful when you are using a polarizer on a wide-angle glass. But because the lens helps cover over the ninety-degree angle from the sun, there won't be a uniform polarizing effect across the whole image.
Q. Where can I get the best polarizer filters?
A. The best and easiest way to get suitable polarizer filters is to scout online on reputable platforms. Do well to search for reviews from past and current customers who have used this product. Also, ensure you only go for products that come with warranties.
