More observations on merging cloud and ice imagery into a single photograph ... here's one assembled with Sketchbook Pro, then tweaked with the "Chrome" Filter from the list of IoS 7 photo apps.
Here's a summary describing the effects of the Chrome filter in Adobe Photoshop: "Renders the
image as if it had a polished chrome surface. Highlights are high
points, and shadows are low points in the reflecting surface."
The Chrome filter can help when deciding whether a given image is worth the extra expense of a metal print (special inkjet dyes on an polished aluminum plate). Metal printing adds brilliance to the image, if at the expense of realism.
