Our images of the year
Geoff Harris Deputy editor Painting the Sky by Thomas Kast
acreous clouds are one of the most enchanting atmospheric phenomena and I love this captivating image, which was a well-deserved category winner in the Astronomy Photographer of the Year competition. If nature is the greatest artist of all, Kast has really captured this, with the beautiful textures, tones and palette. Apparently nacreous clouds reflect colour like oil does on water, and this unique effect really shines through in this image. The processing is not too over the top either, and plenty of detail is kept in the foreground
