Hello,

Another abstract I'm afraid!!!

I wanted to capture a close crop of the amazing contrast and shapes and patterns here - I think that the lack of sense of scale here to me plays a little trick on the mind... it could almost be microscopic, like a scene through an electron microscope - and it could also almost be an aerial satellite view of mountain ridges and canyons.

What actually IS it?... Well it's limestone pavements up at Malham Cove in the Yorkshire Dales - exaggerated by shooting into the bright sun and post-processing with channel mixer and slight boost of contrast.

This is a much weather-softened area of clints (the raised parts) and grikes (the fissures between them) - the formation of which is described here...

"Due to the solubility of limestone, limestone pavements are associated with some very curious and unusual landforms. The most characteristic surface feature of limestone pavements is their division into blocks, called clints, bounded by deep vertical fissures known as grikes. Clints and grikes form under relatively deep cover of soil where water, carrying carbonic acid which is formed from dissolved carbon dioxide as well as organic acids from decaying vegetation, picks out vertical lines of weakness (joints) in the rock. These fissures widen over the years as the acidic water preferentially attacks the lines of weakness. Grikes take many thousands of years to form under the soil as the rate of solution is slow.

Over time, the soil on the top of the limestone platform began to disappear down the newly eroded grikes, and was gradually eroded from the tops of the platforms. Some of the material lost into the grikes was washed deep into the drainage systems of the limestone pavements through connecting fissures, leaving open grikes of a metre or more in depth."

I hope you like the geology lesson and the image!

Thanks for looking.

Doug

Hi Doug

I'm very surprised that noone has commented on this excellent abstract shot until now...a bit disappointed on TN that they "only likes nice but rather common bird shots or other more common animals like mammals" :(

This is a very interesting lesson on geology and also of photography.
I like the B&W conversion here and the harsh contrast that it resulted.
The tight close-up on these limestones is exceptional and the 3D effect that it has is magnificent!
Exceptional DOF choice here that keeps everything in the frame in great focus and very well composed on the vertical.
Truly lovely work!

Bravo and TFS

Hello Doug,
Was a bit curious what they actually were?
Thanks for the geology and chemistry lesson.
