Thanks Karlark.
I'll have try one in Gimp when I get a chance.
Here's my first serious attempt with GIMP. Never would have tried it playing with the contrast and paint like I usually do. Hindsight says it was a poor choice in that I didn't notice the original photo had clipped the float and the top of the nacelle was very bright - wasn't sure where to put the dots....
Many thanks Ken for the tutorials.
Going boldly forward where I've never gone before, I present GIMP No.1...
