Cloud waves

Digital darkroom: histogram correction and slight unsharp masking to compensate for the scanning process. Converted to B/W using the red channel from the original image (like using a red filter, but I don't have one!). Unsharp masking and cropped to square format to get rid of some areas where the window of the plane was reflecting badly some light from the sun.This picture was also taken during a flight from Spain to Finland (I uploaded another one here). We were flying over Denmark and there where some majestic cloud waves right under us. It was quite difficult to focus pointing downwards with the layers of dirty and scratched plastic that make up the windows in the plane.
