The air in Sudan is generally full of fine sand particles which means the setting sun is often obscured. There’s no flare of bright oranges or yellows that you tend to get in the cleaner air away from the Sahara desert and further north.
For this photo I used a weather-sealed 18-135mm Fuji lens at 66mm (around 100mm on a Fujiflm XT2 camera) from an adjacent sand dune. Seconds later the sun had dipped behind the pyramid and a few seconds after that it had slumped below the horizon.
The pyramids and temples of Meroe made a fantastic moody backdrop to an otherwise average sunset.
