David – I appreciate you sharing these images with us and your exploration of composition and processing. In the end I do prefer your colour versions as I think the contrast between warm and fool hues adds depth. Composition ally, I thought I would prefer a horizontal shot - thanks for going to the trouble to do so - but, like you, I prefer the larger rock in the vertical. Now, if that vertical were made square by cropping from the top... Talk about photography by committee!!
