Jura Canyon Again

It can be challenging revisiting a site, especially a site which had some pretty obvious views such as this narrow twisted canyon.

I made an effort to look for alternative views. Previously I'd centred the canyon opening and decided this time to heavily bias the left hand side. I had doubts about adequate depth of field but as I was stitching, I didn't want to both stitch and blend for focus. In reality the depth proved ok at f16 and 17 mm., mind you I have noticed that this lens (17-40) tends to have a curved plane of focus, that is the edges focus nearer than the centre so it actually worked to my advantage.
