»The NiSi GND8 (0.9) medium filter in test«

As an ambassador for NiSi Filters, it is always nice to get new products for testing. NiSi Filters is constantly working on the filter systems to improve and expand the product range to provide photographers the best solution for every requirement.

The latest development is the NiSi GND8 (0.9) medium filter for the 100mm system with a medium-strong transition. After I tested several GND filters of NiSi (GND Hard / Soft / Reverse), which are all very good, it was quickly clear that a filter is missing.

A GND filter, which is ideal for adjusting the exposure when buildings, mountains or other objects hover over the horizon. In the next few lines I would like to tell you my experiences with the NiSi GND8 (0.9) medium filter.

Why is a GND filter useful?

Our human eye can adapt to different light conditions. You can see the details of the bright and the dark areas at the same time. Unfortunately, our camera can not do this. However, in order to produce a balanced exposure, I use graduated neutral density filters. In this way, I can darken light areas and make the shot more balanced. 


Like all NiSi filters, the medium filter is made from high quality optical glass (not resin) with nano coating to prevent losing any single bit of detail. It also provides true to life color.

Here you can see the direct comparisons.

The left-hand areas are  taken without a filter, the right-hand areas with the NiSi GND8 (0.9) medium filter.

As you can see, in the left areas the sky is over-exposed. Without filters I have to take two shots and put them together in an image processing program.

The right areas are balanced and harmonious. By using the NiSi GND8 (0.9) medium filter you can achieve a perfect exposure with one shot.
