Chris, I THINK I can see what you're getting at...
Here's a lighter version. I've only just learnt how to manipulate exposure and things... so I keep forgetting that I can. Mind you, I still need to know what other people need to be able to see in order to get it right!
:D

Drat, there's obviously more info in this version, it didn't upload. I'll crop again and try again...
