I want to learn the technique needed to take this kind of picture. The exif data of that photo mentions 16-85mm as the lens used, which is not a macro lens AFAIK.
I have a Canon 18-55mm lens and 50mm f/1.4 lens.
This is easy to do all it takes is some experimentation and patience.
The shot above was most likely cropped to achieve that composition.
As far as I can tell, its just a photo of a bubble which has had strong contrast and saturation adjustments in Photoshop. A macro lens is not necessary if you have a large bubble and moderate distance from the lens.
This isn't easy due to the random movement of bubbles and difficulty of close focusing on a moving subject, so expect to take a lot of tries to replicate this!
