In the last few years, it seems a number of new filter manufacturers have popped up, significantly improving the competitiveness in this particular market. Neutral density filters have been known for being quite expensive and this one of the key reasons why many photographers still avoid using them. In recent years, however, companies like NiSi Filters and Breakthrough Photography have been delivering some incredible products with much more palatable prices to help photographers get the look they desire. In a previous comparison done by Fstoppers, Patrick Hall demonstrated how good the filters from Breakthrough are, and in fact, they won that particular comparison. Breakthrough claims their filters are the sharpest and most color neutral in the world, so I wanted to see how they perform against NiSi.
