My Dad... Time & Tide Marks

I discovered Photoshop Express on iPad so had a wee play around with this old picture.
It shows my dad, Donald, with his old neighbour from Carrbridge, Trixie Cuta (nee Calder). It must have been taken in the late 1940s/early 1950s when my dad was a student.
Spot the sun tan where his long socks must've been!
