Cheers Moth,
I can definitely say I've been inspired by Mr McLiam's v. snazzy images, and I've recently had some sound advice about post-processing. I've had all sorts of fun experimenting, but it's not easy to get out to sites in the dark whilst on a pushbike! Had to blag a lift for that one.
I'm dead keen to try the same palaver at Long Meg, pick out those carvings. Until then, it's back to faffing about with DIY RA on the rocks in the back garden...
