Hope someone here can help. I'm after some new ND grads (old ones are scratched to hell). I hear everywhere that Hi Tech filters are better than Cokin, but I'm struggling to see it. The one review I've found that has the same shot with Cokin & Hi Tech grads has no difference that I can see. Can anyone show me sample shots of the same scene taken with the same settings with Hi Tech and with Cokin filters? I'm particularly intersted in how well they work stacked one on top of the other, because that seems to be when my Cokin ones give me most trouble with that purple hue.
