The second NiSi filters introduction workshop

Last Sunday it was time for the second NiSi-filters landscapephotography workshop. This workshop is part of a series of workshops in collaboration with camera shop Foto Sipkes, distributor Transcontinenta and NiSi Benelux. Through this post I would like to share with you, the behind the scenes of that evening.

We had beautiful weather with beautiful clouds in the sky. The group was enthusiastic and very nice. Everyone was having a great time! If, after reading this post, you also want to participate in the NiSi filters introduction workshop, you can find the dates for the following workshops below. All behind the scenes photos were taken by Dennis Zuijderduijn.

During the workshop we had a beautiful sky. Unfortunately these clouds had left around sunset and the sky (except for a thick band on the horizon) was completely empty.


Upon arrival, participants got coffee or something fresh, and an introduction talk was given briefly. After which the filter sets were handed out to each participant. In this workshop the emphasis lies on actually experiencing the use of filters (with of course help and explanation in the field). That is why I try to keep the theoretical story as short as possible.

The workshop starts of course with coffee / soda and an introduction talk, after which the filters were quickly distributed.

At location

It is a short 5 minutes walk from the parking lot before we reach the location. Very nice because everyone is well packed. If you want to work with filters, you of course need to bring a tripod. Because of the warmth everyone brought extra drinks too. Not unimportant because we are in a field without shade and it is still above 25 degrees Celcius.

After a short walk, we arrived at location and everyone starts unpacking and getting things ready.


In my view, one of the most important filters is the polarisation filter, in particular because its effect cannot be simulated in post-processing (read more about this filter here). For this reason, this is the filter that is discussed first. After a brief explanation about how to use this filter, and it’s possible pitfalls, a demonstration is given.

The polarisation filter is a great tool for improving your photos. There are, however, a few pitfalls that I demonstrate here. When you know what to look out for, this filter is very easy to use.

The medium gradual ND filter

The next filter that participants work with, and that is used by me in at least 80% of the cases, is the medium gradual ND filter. This filter is very versatile thanks to the medium transition from light to dark. Moreover, it is much easier to use than, for example, a hard edge filter. To demonstrate this, I aim the camera straight at the sun, which is partly covered by a cloud which in turn creates beautiful light rays.

Various questions are asked during the workshop. Here we take look at the effect of the medium edge filter on the histogram.

Slowing things down using an ND filter

After having played with the filters for a while, there are a number of participants who would also like to test the grey filter (ND) filter. In the meantime, most of the clouds have gone, but luckily there are still a few left to illustrate the effect. Important with the ND filter, and great with NiSi, is the tape that closes the space between the filter holder and the filter. This prevents light leaks. It is therefore important that the ND filter goes into the filter holder first!

Here I explain why it is important that the ND filter must be in the holder first; the foam on the back ensures that any light leaks are prevented.

The final rays

While the last rays of the sun are shining over the cloud band, and the flies are starting to plague us, it’s time to pack. Everyone has been able to test the filters extensively and have made beautiful pictures. Back at the cars we have a small follow-up discussion and everyone gets a goody bag. After that unfortunately, the workshop is over. It was a great evening and I want to thank all participants for their presence!

The last rays shine over the cloud band and the flies begin their hunt. In short: time to leave!

Thank you very much for reading!
