Recently I took a special flight over the southern Highlands of Iceland in a Cessna 207 equipped with open windows. I got very lucky with the conditions: diffused light of the high clouds interspersed with glancing sun beams. It will take me some time to sort through the photo shoot. For now, a few teasers.

These are beautiful! Looking forward to more.
Just unreal, Rajan! If this is a teaser then I cannot wait for the feature presentation.
Are the first two images processed using the Simplify plugin (Horseplay)? And what is it, clouds or river or smoke?
It is a glacial river. No Simplify/Horseplay plugin was used.
