Lengthen your ex­po­sure with ND fil­ters

1 Com­pose and fo­cus Set up your tri­pod in a po­si­tion where you’re able to stand for sev­eral min­utes with­out get­ting in the way of peo­ple or block­ing pave­ments. Fix your cam­era, com­pose the shot and fo­cus the lens be­fore you at­tach the fil­ter, then switch to Man­ual Fo­cus to lock it.

2 At­tach an ND fil­ter At­tach a neu­tral den­sity (ND) fil­ter to your lens to re­strict the amount of light reach­ing the sen­sor. This will en­able you to shoot su­per-long ex­po­sures. We used a thee-stop ND fil­ter here. Each stop dou­bles the amount of time needed for a cor­rect ex­po­sure, so a 10-sec ex­po­sure be­comes 80 secs. 3 Set Bulb Mode Set the cam­era mode to Man­ual. Use ISO100 for max­i­mum qual­ity and low sen­si­tiv­ity. Choose a nar­row aper­ture like f/16 or f/22 for max­i­mum depth of field, then set shut­ter speed to Bulb. This means the shut­ter stays open as long as the shut­ter but­ton is ac­ti­vated.

4 Ex­per­i­ment with THE Ex­po­sure TIME You don’t want to touch the cam­era dur­ing a bulb ex­po­sure as this could blur the im­age, so use a re­mote. Ex­per­i­ment with ex­po­sure time – start with a minute, then try longer or shorter de­pend­ing on the re­sults (we used 92 secs).
