What is light and how do we use it     posted on 1st of october, 2009

The only real problem in photography be it stock, microstock, art or otherwise, is and always has been light.

Light is the electromagnetic radiation visible to the human eye. In classical physics the wave of electromagnetic radiation has amplitude, which is the brightness of the light, wavelength, which is the color of the light, and an angle at which it is vibrating, called polarization (reflecting windows anyone?). In quantum physics electromagnetic radiation consists of particles called photons, which are packets ("quanta") of energy which move at the speed of light. The brightness of the light is the number of photons, the color of the light is the energy contained in each photon, and four numbers (X, Y, Z and T) are the polarization.

And as weird...

Sink your eyes into the light and you will always see different shapes and places, you will always feel different. Just have the courage to press that button.

When did your passion for light appear? Probably when you poped out and started crying. World is a strange place but we always like the light. Why not record it?

I realised that there is no such thing as art photography, when you create an image you always do it from the heart.

More images, less words, I always say. Let the photo speak for itself. Of course this doesn't always work, sometimes we need words to be able to communicate. But I like to think that our eyes are the windows of our souls.
