What does a UV filter do for the camera?

As the name suggests, the UV filter helps mainly against the sun. By its very nature, it ensures that the intense rays do not penetrate to the sensor and damage it. Despite the sun visor, sunlight can always fall right into the lens and then such protection is useful. But the UV filter also serves another function that cannot be derived from its name. Since it is usually the cheapest of all filters, it can be used to protect the outermost lens glass. Anyone who, for example, has ever dropped the camera on the floor with the expensive lens in front when taking a photo will quickly learn to appreciate this protective function. Most of the times, in such a situation, only the glass of the filter shatters and the lens remains undamaged. Even in crowds, for example at the Christmas market, pointy objects often come into the immediate vicinity of the lens. Those who then do not have a cover on the lens are at least protected by the UV filter.

What is a polarizing filter used for in photography?

The polarizing filter is a real all-rounder, as it combines several functions in one attachment. Those who see such a filter for the first time will immediately notice that something can be adjusted here. Especially the circular polarization filters can be easily adjusted as desired by twisting them. Depending on the setting, the polarization filter changes its polarization direction and thus has two different effects:

  1. Intensify colors - Turning the filter changes the contrast. The effect is already visible in the viewfinder and can therefore be adjusted to fit exactly. It is therefore worthwhile to use this polarizing filter especially for landscape shots, for example of colorful flower meadows, in order to provide a higher contrast. Of course, the colors in the picture can also be changed later with an image editing program, but the less work you have to do with the picture afterwards, the better.
  2. Reducing or increasing reflections - In opposition to contrast, reflections in glass panes or in water cannot be changed later, but can be changed directly when taking the picture with a polarizing filter. When photographing with a polarizing filter, it is best to focus on the subject first. Then, turning the filter brings more reflections or makes them almost completely disappear. The use of a polarizing filter is especially worthwhile when photographing fish or when the photographer just wants to achieve a clean reflection on a lake.

Why do I use a grey filter in photography?

ND filters, or Neutral Density Filters, Neutral Density Filters or Gray Filters, are often used by professional photographers to ensure that the images are evenly lit. This is a lens made of optical glass, tinted in a light shade of grey, which can be screwed, magnetically attached or inserted in front of the lens.

With such a neutral density filter, very good photos can be taken regardless of the incidence of light and sunlight. We offer many different models that differ in tone and light transmission. Another reason for using such filters is the reproduction of a surreal image effect due to the increased exposure time. As a result, movements can be "fixed" and so-called wiping and flowing movements, such as the flow of water, cloud movements or moving cars in a big city, can occur.

How does an ND filter work? 

In principle, an ND filter is nothing more than sunglasses for your cameras and allows less light to enter the lens. This reduces the amount of light hitting the sensor and artificially lengthens the exposure time of the camera by a fixed factor. Grey filters are available in various thicknesses, which can be used to achieve different exposure times in photography. Even if most of these filters appear grey or black, colours and sharpness of the images are not affected by the grey filters we offer. Just like the polarizing filter, the effect of an ND filter cannot be reproduced digitally. Below is a table that is very useful for using ND filters. It is listed which ND filters cause which extension factor of the exposure time. Furthermore, the reduction of light incidence in apertures and the value of the neutral density are shown.

What can the Neutral Night Filters be used for?

Clearly primarily for use in nocturnal landscape and astrophotography. By using our Neutral Night Filters on your cameras, you can achieve more details in the images and a much clearer and higher-contrast image of stars and astronomical deep sky objects. Our Astro Filter reduces the light incidence by about 2/3 aperture. 

Did you know that even a city with 25,000 inhabitants is sufficient to artificially brighten up the surrounding area within a radius of 20 kilometres, making the night sky appear duller and less contrasty, or to give night shots a yellow tint. The artificial light sources that cause the greatest light pollution are sodium vapour lamps and mercury vapour lamps. Among other things, these wavelengths block our night light filters and thus allow you to take starry skies and night shots without a yellow cast.

How do the Astro filters from Kase Filter work?

In order to understand how exactly the night light filters of the Astroklar series work and how they facilitate astrophotography and night photography, one must understand how exactly the so-called light bells are created. The part of the artificial light that is radiated upwards into the atmosphere reflects again on the atmospheric layers, like on atmospheric dust and water, and is thus widely dispersed. This creates the so-called light bell, because the air is brightened and light penetrates it. A city with about 25,000 inhabitants is enough to brighten the sky within a radius of about 20 kilometers and thus to disturb astrophotography and city and landscape photography at night by light pollution. It is therefore a side effect of industrialization.

The biggest producers of light pollution are industrial plants, big cities and highly directional spotlights from airports or high beam from cars and light art like skybeamers and laser shows. This light smog then envelops nocturnal motives like a kind of veil, so that the natural night light appears yellowish, thus reducing the visibility of stars.

Our Astroklar filters are specially coated so that almost all light waves of the entire colour spectrum can pass through and mainly the yellow and orange light wavelengths are blocked. This prevents the unwanted wavelengths from reaching the camera's sensor. The resulting cleaning of the light waves provides for more detailed images with considerably more brilliance and structure, especially in nighttime city and landscape photography or astrophotography.
