Per my usual modus operandi, I found a view that I thought would make a nice vertical panorama, and took two frames to stitch into a panorama. It seemed like a good idea, by it did not turn out well. Plan B was to forget the panorama and instead crop in to the red flowers. In Photoshop I selected the sky, feathered the selection, and darken the sky by 25%. I reset the black point with Levels.
