Kase Armour 100 Magnetic Square S- GND 1.2

This Armour 100 magnetic S-GND1.2 gray gradient filter of 100x150mm is specially made for the Kase Armour magnetic system. The edges of the frame are finished in such a way that no light from the sides and back enters the image, so you have no annoying reflections. You can easily place this filter in the magnetic holder on your lens. The magnetic attachment makes it possible to smoothly slide the gradient filter up or down, making it easy to adjust the gradient to the horizon in your image.
 

GND (Graduated Neutral Density) gray gradient filter
GND gray gradient filters have a gradation (gradient) that varies in strength and density across the surface of the glass filter. The filters are often half ND gray filter and the other half is clear. When photographing with long shutter speeds, it is important to be able to control the light. Depending on what you want to block the light from, you can place the gray gradient filter in the correct position. A GND gray gradient filter is often used together with an ND gray filter.
The gray gradient filters have different types of transitions, with different application options.
A soft edge S-GND gray gradient filter is best suited for mountainous, forested or urban environments, where the horizon does not have a flat straight transition.
A medium edge M-GND gray gradient filter can also be used in similar areas to the S-GND, but care must be taken as you need to watch out for dark lines that may appear over trees or buildings.
A hard edge H-GND gray gradient filter is best used in open areas, where there is nothing on the horizon, such as coastlines and open plains. With a hard gray gradient filter, the transition from light to dark is clear and fast and is ideal for sea and desert landscapes.
