Panorama of the island Nunâ east of
Upernavik and south of
Aappilattoq in
Greenland. Photographed south of the island during a sail trip to Upernavik Icefjord. The mountain, which extends 270 m above sea level, is inhabited with
Glacous Gulls (
Larus hyperboreus). The white areas are bird droppings. The yellow areas are
lichen (probably
Caloplaca and
Xanthoria) adapted to the nutritious environment. The image has been generated using
Hugin based on 17 individual photos arranged in three rows. The images were taken with a hand-held camera (
Canon DIGITAL IXUS 800 IS) in a small boat that was slowly drifting (not optimal, but it was too deep to anchor). Vignetting has been minimized using a best fit polynomial in Hugin. The output image from Hugin has been rectangularly cropped in
GIMP. The colour value curve has been modified slightly to compensate for over-exposure in certain white areas. Hereafter the photo has been
Smart Sharpened with a pixel radius of 3.0 and an amount of 30%. the inverted edge detected mask was used in RGB to apply a selective gaussian blur with pixel radius 5.0 of the sky in an attempt to remove noise there. "Missing sky" in the upper left corner has been pasted in by simple colour picking and painting (do not know other methods).
