ND grads are a must for Landscape photography, even more so in the cloudy days in Scotland.
Even with my 2 stop ND Grad on I still sometimes struggle with the skies, thats where Post processing comes into play.
I only started photography back in November last year, I only started using photoshop about 2 months ago, I spend a lot of time enhancing both skills.
Why don't you get yourself along to one of our Scottish get togethers, it's not an exclusive club 
I've only met a few of the guys once, you'd be amazed at how human Dimitri actually is I used to think he was just a machine that churned out great shot after great shot He's a top bloke who is just bursting to help people.
We have a meet next Month in Glen Coe, the whole Scottish POTN landscape contingent will be there with all there fancy gear
