Bubbles

I have been playing with bubbles (never grew up) and found it extremely difficult to get good images with a large enough proportion of them in focus.

I did manage to get 7 focussed shots of a single bubble as it dropped vertically in front of the camera. I have used 4 of those shots here and put them together in one image. If you look carefully you can see that each image is different, but it is just one bubble.
