I recently purchased a NiSi Natural Night Filter, a filter designed to block certain wavelengths of light, namely those produced by sodium vapour and mercury vapour lamps. Sodium vapour city streetlights are what cause night shots in cities to have such a dominant yellow/orange colour cast. In the animated GIF image above, you can see what a dramatic difference the filter makes! Also check out the linked gallery above for some extensive comparisons.
Not yet having an existing drop-in filter holder, I also bought NiSi's filter holder system kit. I have not tried any of NiSi's other extensive set of filters, such as graduated NDs or the like, so my review is rather specific. For simplicity sake, I will refer to this filter as the NNF from now on in the following review...
