ND Grads - Hard or Soft?

[greengiant]

Looking to order a set of ND Grads soon (probably go for Hi-Tech ND Grads as they aren't that much more expensive than Cokin or Kood grads).

Not sure whether it would be best to go for hard edged or soft edged grads. With the crop factor of the camera being 1.5 would a hard edge be more like a soft edge? Also what strengths should I go for?

Thanks in advance!

That seems pretty cheap, which brand are they?

Another thing to watch out for is that a 3 slot holder will be quite chunky so if you're using a wide lens then it might get in the shot.

Those are Hitech filters. From the one UK stockist. Seems a good price. Price exludes VAT
