The Circular Polariser
Look at the side of the car. It was photographed in bright November sunlight, so the side of the car, fully exposed to the sunlight, should be overexposed in comparison to the rest of the vehicle. On this image, a circular polariser filter was used n the lens of the camera, eliminating the effect of the UV rays on the highly polished surface of the car.
My filter is made by HOYA. Here’s an extract from their website:
A circular polarizer is designed to do one thing: remove or control reflections from surfaces like water, glass, paint, leaves, sky, buildings, streets, and the list goes on. When light hits those surfaces they create glare that increases highlights, reduces color and detail. Almost every scene contains some kind of glare, and a circular polarizing filter will help you control that glare before it ever gets to your image.
A polarizer frame is made of two pieces attached together. One holds the glass and the other attaches to your lens. So, once the filter is secured to the lens, the front part of the filter will rotate freely. It is this rotation that will allow you control the polarization effect. By looking through your viewfinder or at your screen begin rotating the filter until you get the amount of reflection removal you need. Depending on the lighting conditions the effect may be dramatic or subtle so really pay attention to the details and the areas that are most important to you to control. Below are examples of common subject where a circular polarizer is used.https://hoyafilterusa.com/pages/how-a-circular-polarizer-works
The image was made with the Fujifilm X-T3 Mirrorless Camera, F=50mm, f/5.6, @ 1/60th second on ISO200
