did you really do all three drops at once? or did you create this grouping after the fact? i'm only wondering to know if the overlap of rings on the surface happen. (either way the photo is amazingly wonderful and i'd love to have it in my group 'm m multiples s s' - if you want)

Thank you for your kind comment.
The photo's were combined in Photoshop.
I only have a single drop set up.

Exzellent!
