Amazing closeup pictures of bubbles - like you have never seen before
Creative Review commissioned photographer Jason Tozer to shoot these pictures on behalf of Sony using its new Alpha digital camera. All common-or-garden soap bubbles, shot in-camera!
And my favorite:

To learn how the pictures were taken, please visit here ; but essentially they blew up soap bubbles and took pictures with Sony’s new alpha Series SLR camera.
The iridescent colors of soap bubbles are caused by interfering light waves and are determined by the thickness of the film. They are not the same as rainbow colors but are the same as the colors in an oil slick on a wet road.
As light impinges on the film, some of it is reflected off the outer surface while some of it enters the film and reemerges after being reflected back and forth between the two surfaces. The total reflection observed is determined by the interference of all these reflections. Since each traversal of the film incurs a phase shift proportional to the thickness of the film and inversely proportional to the wavelength, the result of the interference depends on these two quantities.
Thus, at a given thickness, interference is constructive for some wavelengths and destructive for others, so that white light impinging on the film is reflected with a hue that changes with thickness.
