I was sent an email link to this site (from Tom at Glorious Creative) back in August 2006 and only rediscovered it whilst doing some clearing out. The site features some great images of the flyde coast in the UK.
Run by David and Libby Nightingale they offer not only commercial photography services but also photoshop trickery lessons both online and face-to-face. Below are some examples of manipulation and original from their site.
Nice images! I remember when this boat washed up on Cleveleys shore… right near where I live!
