I found this on Flickr and loved it. It is a stunning picture with great compositional elements and spot on focusing.
I love the colours and the overall feeling of sunset tranquillity it gives.
One of the impressive fortresses dotting North Wales:
This castle is owned by Cadw but seems to have few visitors, which is a shame as it is fascinating. The diversion of the river and building of a tidal moat are interesting enough in themselves, but the structure of the castle is remarkably intact.
I am a sucker for high contrast black and white. Too often BW images get uploaded to flickr when they are actually tones of grey. This can look good in its place, but for me at least, black and white wins out every time.
This is a great example of the contrast working well. In colour, if you didnt know the people, this may well be a bland image. In black and white it screams dramatic.
For people interested in recreating the sometimes stunning effects of pinhole cameras, there is a tutorial on the Ogum blog looking at how this can be done in photoshop.
