Thanks very much for that, very helpful! So I gather if you get a bigger holder you are able to get an adapter to fit to smaller lenses? I guess that would be the way to go then. I'm sure you've gathered i really am VERY new to all this!!
I shall now go exploring!!
I'm thinking possibly soft edged filters to play around with first. A lot of the landscape stuff i'll be doing will be seascapes.
Thanks guys!!
