Robert & Shana ParkeHarrison

I recently came across the work of Robert & Shana ParkeHarrison and I found there photographs strangely beautiful.

This one I found really strange but the colours and the composition of the picture makes it beautiful to look at.

I find their work relates alot to nature: water, animals, trees, and organic subject matter.
The colours they use range from dull greys through to dark blues, aqua and hints of coral.
If anyone has anymore knowledge of their work or how they create such beautiful pieces I'd love to hear.
