Tiny issue? I am already sick and tired of manufacturers putting their bug products on the market just in order to overtake the competition. The customers are then very often persuated by service that it is not an "issue", but "property" of the product. I had similar experience with TV, mobile phone, lens. What kind of strange world do we live in?
There is not too much to explain :-) I used black background and remotely triggered flash. The particular bubbles had different distance from camera, that is why some of them were pin sharp and others - out of focus.
Great shot! Having known the sculpture existed, I would have visited this place during my July stay in Singapore :-) BTW, I was deeply impressed by this city.
