Overview of all Kase square filter types
Kase offers the following types of square filters in the sizes 100x100 mm and 100x150 mm:
- CPL / Polarising Filter: Reduces reflections on reflective surfaces. The polarising filter can also be used to make the sky appear bluer and the green of leaves more saturated.
- ND Filter: For slowing down the shutter speed or alternatively for changing the f-number individually, even in bright conditions. Kase ND filters are offered in ND8, ND16, ND64 and ND1000 strengths, so there is a suitable filter for every situation!
- GND Filter: GND filters (also called grey graduated filters) can be used to increase the exposure time. Above all, however, grey graduated filters are intended to make certain areas of the photos appear darker. For this purpose we offer filters in different strengths and variations such as soft, medium, hard, reverse and centre GND.
If you do not yet have a suitable filter holder for your camera/lens for our rectangular filters, take a look at our kits, which contain everything you need to get started! You can also find our filter holders separately under the category Filter holders.
