I havnt done any photography for a while, I was given some time ago a Lee filter holder for 100 mm filters & a 0.9 ND hard edge grad filter. I would like to get out & shoot some landscapes & was wondering which would be the most usefull ND filter to add to my huge collection of 1:shake:. I cant afford the full set at the moment:shake: so will have to buy one at a time. Soft edge or hard edge? 0.3or 0.6?
