Wow, beautiful colours. Are sunrises/moonsets typically like that in the Nullarbor, or was this a particularly colourful day?
The horizon is also clearly curved... I know that the 70-200 f/4L is a very good, low-distortion lens... so I'm guessing it's Earth's curvature?
Thanks again all
Nearly every day is just as colorful all depends on the clouds around really (if any!) the horizon was very flat out there with little to no features around to go off.
