Your Bubbles

Greetings and welcome to Hohenfels Volks, THE place for our place. Another cold and frosty morning stirs through Hohenfels and the surrounding area like a spoon through cocoa.

Our first post today features all the submissions your submission from last week’s theme, bubbles of light. Once again, Jennifer was the only one who submitted. Here’s the great shot she gave us.


Jennifer’s bubble

It’s very interesting, and it shows us how light can have its ups and downs, as it were. Using the lamp the way she did, shows us exactly how light can form a bubble. By putting herself in the corner, and using a somewhat rounded light source, she created a bubble of light around herself. You can see the light falloff on the 2 walls and the shape of the light itself really worked in this shot.

Due to the nature of light, you can create a source that seems to be a bubble using anything rounded. One good way to see the bubble is to place an IPad with a white screen face up under a semi-transparent Tupperware bowl. When you place a vertical object next to it, you can the bubble shaping up, just like the bubble that took form in Jen’s photo. By placing more objects at differing distances from the light source, you can create even more of a bubble. It’s all caused by light and the physics behind it. The primary thing to know about light is the inverse square law. If an object’s distance to a light source is double, the light’s apparent power is quartered due to spread and the nature of light.

In a later post today, we’ll be going to Nuernberg’s Christmas market, so get your camera ready!
