Introducing the long exposure Kit #2, Joel Tjintjelaar signature edition, this long exposure kit includes 10, 13 and 16 stop ND filters. The Long Exposure Kit #2 is for users who wish to forgo the versatility of stacking 3, 6 and 10 stop filters and commit to a single filter solution for their long exposure photography. Kit #2 features 10, 13 and 16 stops of Firecrest ND. 10 stops is a good general purpose long exposure filter for landscape. 13 stops are ideal for 2-3 minute exposures on seascapes, where the meeting of land and sea causes clouds to move more quickly across the frame than usual. 16 stops is the standard bearer of long exposure technique a single filter capable of 5-8 minute exposures.
