Looking for some skookum Neutral Density filters? I bought these last June, have used them maybe 5 times. They are too advanced for me. For the amount I use NDs I need something much simpler.
NiSi V5 PRO filter kit - $500 FIRM
NiSi V5 PRO filter holder with step up rings and Pro CPL
NiSi 100x150mm 3 stop IR soft graduated ND filter
NiSi 100x100mm 6 stop IR ND filter
NiSi 100x100mm 10 stop IR ND filter
$500 for all four items above - best bought and used as a package to create long exposures and control light for sunrises and/or sunsets (Amazon retail is $817)
