Ebony sw45 w/ Super Symmar 110mm xl
Fuji Velvia 100f
Hitech 0.6 ND Grad Soft
Pretty sure this shot used the Hitech soft grad (really need to make notes) Personally I can't see any color shift caused by the Hitech. Going to pick up a hard grad set and see how they go.
nb. tryfan should look pinker than it does here on flickr, dunno whats goin on there!?
