There are still optical camera filters that provide effects that software cannot duplicate.
Filters make it possible to capture images in a variety of ways and with effects that would be impossible without them. In bright sunlight, exposures of a few seconds or even minutes can be achieved by using a neutral density filter to stop light from entering the lens. Polarizing filters can expose buried detail by cutting through glare on reflecting surfaces like glass and water.
Some of these effects, like the ability to add a graduated neutral density filter to darken the skies, can be accomplished using post-production editing tools. But it’s best practice to capture the appropriate exposure at the source, to avoid clipping in highlights and shadows. Your software won't be able to restore the sky if it was overexposed when the photo was taken. Additionally, because of the way light actually bounces off surfaces, editing technology cannot yet reproduce filters like thepolarizers.
The vibrancy and contrast of your photographs can be enhanced by using polarizing filters, often known as polarizers. They eliminate haze, which improves the color of skies and lessens undesired reflections in water and glass. An affordable polarizer is a great investment for virtually any photographer since it creates a unique appearance that is difficult to duplicate in post-processing.
There are two varieties of polarizers: circular and linear. These names actually describe how they polarize light, which can either be light that has been reflected and is traveling in a circular path toward the camera or in a straight path vertically or horizontally. We can see behind reflecting materials like glass and water because non-polarized light is left over after this light is removed. Use it to see through the water, brighten greenery, deepen blue skies, or take the gleam off the glass.
When shooting in the daytime, a polarizing filter reduces the amount of glare and haze from the sun by filtering out specific light waves. When photographing rivers, lakes, or the ocean, they really shine; hence eliminating reflections enhances the overall quality of the photograph and allows you to capture the character and color of the water with much more depth.
This is a challenging effect to replicate digitally, even with the best photo editing software. Polarizers have maintained their popularity in the digital age, much like the best neutral density filters, since they do something special that happens at the moment of capture.
Besides, to lower the amount of haze in an image, a UV filter is made to block off undesirable ultraviolet light. Even if employing digital sensors makes this somewhat of a leftover from the era of film, it can still be helpful and surely won't hurt.
As they provide a crisp, undistorted vision, UV filters—originally created to combat atmospheric haze in film photography—are now employed to protect the front element of lenses.
The filter, which is made of tempered glass, minimizes optical distortion and flare while keeping the lens quality in pictures. Naturally, the multi-coated glass in this instance shields against the damaging effects of UV light and removes haze that could give the image a bluish hue. It seems like you can't go wrong with this one because it promises top-level light transmittance, ideal clarity, and color fidelity.
