A nostalgic shot that I reprocessed. Taken from Wiruna during my last visit earlier this year. Canon 7D and a Tokina 11-16mm lens. There was a bit of murk around at the time.
This was a 180 second exposure at F2.8 (fully open) at ISO 800.
The Tokina lens is pretty sharp. The little bit of coma at the edges can be softened by adding a bit of barrel distortion in PS to squash it back onto shape (only a little bit is required)
