A close view of the glacial ice field, which forms the stunning backdrop to Fjallsárlón lake, to the west of Jökulsárlón, Iceland.
This was taken at 400mm and then cropped from the image below, as I feel it emphasizes the fissures and makes for a more compelling composition.
I prefer the colouration and variety of textures in the wider shot, however.
To give a sense of scale, this was shot from the opposite side of the lake, which measures approximately 1 mile across, as measured on Google Earth.
