Sunset at Hecla Island provincial park in Manitoba, Canada. After the sun had set I tried some long exposures and liked them better than the shots with the sun in the frame. This is a cropped panorama; one of the perks of shooting with a lot of megapixels is that the cropped panoramas are still high resolution.
This photo isn't technically abstract, but the shape formed by the melted snow certainly is. This was shot near Churchill, Manitoba, on the way to viewing polar bears.
This was taken in the Seven Lakes district of Bulgaria. If you are in Bulgaria make sure you don't miss doing some hiking in this area.
