Chile Twilight Pan with Left and Right segments Minimal processing -- slight brightening, but no contrast or color enhancements to prevent any dithering or stepping of colors across sky with subtle color gradations. Final spotting of dust specks done to this image, not layered version -- it still has specks in it. Taken with 28mm lens, Kodachrome 25 film, two segments stitched together in Photoshop. Taken at Las Campanas Observatory, April 1993. Observatory domes visible at lower right. Latitude = 30° S, so waxing crescent Moon is backwards -- this is an evening sky scene.
Chile (Las Campanas Observatory) evening twilight (spectrum of colours tinted reddish-purple from Mt. Pinatubo volcanic ash), with waxing crescent Moon in sky. Yes, this is an evening scene -- Moon looks backwards because this is 30° S latitude. Makes a good comparison with Arizona Twilight, with similar Moon but at different angle due to latitude difference of 60° (Arizona = aboout 30° N) April 1993, Las Campanas Observatory 28mm lens, Kodachrome 25 slide film
This is a composite image showing a pass of the International Space Station on June 21, 2011, summer solstice night, taken from my home in southern Alberta. This is from a stack of 104 3-second exposures at f/4 with the 8mm Sigma fish-eye lens and Canon 5D MkII camera. North is at the bottom, west to the left and east to the right. The images were stacked with Chris Schur's Photoshop Action for creating star trails.
