The iridescent soap bubble is a hollow, thin, spherical film of soapy water. Life span of a soap bubble is usually only a few seconds prior to bursting. The effect of light shining on a bubble gives the appearance of changing colors. These colors are not the differential refraction type that arises in rainbows. Instead, soap bubble colors occur as a result of the interference of light as it reflects off both the front and the back surfaces of the thin, soap film. Different thickness of the soap film effect how the colors interfere both constructively and destructively.
The merging of two or more soap bubbles creates a shape that minimizes the sum of their surface areas, compatible with each individual bubble’s volume of air. In equal sized bubbles, their common merged wall is flat. If one bubble is bigger than another, the smaller, higher-pressured bubble pushed the common wall into the larger bubble. Where three or more bubble meet, as in Bubble Design, the bubbles sort themselves into an arrangement where only three bubble walls meet along a line and the angles between them equal 120 degrees. It takes four bubbles to meet at a point. And, of course, bubble a long-time favorites for child’s play.
Bubble Design image was photographed with a macro lens. Macrophotography is an extreme close-up photo in which the subject size in the image is life size or greater than life size. The ratio of the subject on the plane of the sensor plate is known as the reproduction ratio. A macro lens is usually capable of producing images greater than 1:1. Reproductions of greater that 1:1 are also known as photomicrography. In this digital age, a macro photograph is practically defined as a photograph with its vertical subject matter at a height of 24mm or less.

Creating portals of light, love, joy, beauty, compassion, hope and gratitude is my lifelong passion and gift for the earth, hence the name of my art business, For the Earth. My mother painted in oils when I was young and encouraged my own drawing, painting and handcrafting in all forms. My father, the photographer, gave me my first camera at age 8. As a result of these loving influences, I am a lifelong student of both mediums. I am grateful to my wonderful Pacific NW painter teachers, Stan Capon and Edi Olson, for training my eye and technique. I hope you will enjoy this image as much as I enjoyed its creation.
