At Vilanculos, looking over the sea at low tide. The low tide lightens the colour of the sea, showing dry sand in many places. The deep channels remain a deep turquoise / blue colour. Sometimes it looks as if you could walk to the islands.
Many photographers looking at this shot will immediately think “polariser”. That’s what I as soon as I saw the picture. A dig in my camera bag unearthed the Cokin mounts. But no filters! The filters were back in the UK, after I did a last minute camera bag change! It just shows – check your kit, and check it again!
Here’s a similar picture with a sail.
