Well I finally got there (well got somewhere). After Richard Heeks pointed me to Paulos75 photostream I've been trying to replicate something similar. Not as easy as he makes it look!
Can't believe the effect when you get it though. This is just a macro shot of soap bubbles from above, with the right lighting, which was the key!
Need to get this sharper though.
The black circle is the reflection of the end of the lens.
As one of my contacts said yesterday "this way madness lies" after tonight I can well believe it!
