While in Mombasa on the Kenyan coast recently, I got up super-early to catch the rising sun (on camera).

Close to shore was a small ‘glass boat’ – ready to take tourists later in the day to look at colourful reef fish through its see-through floor.

At first I missed the flicker of distant lights beyond the reef, but with a zoom lens and slow shutter, two commercial liners came into view. They moved slowly towards one another, then crossed paths.

Same shore, different scales and o-so-different realities in the deep blue.
