Michał Kubalczyk Thanks! :) There are two sources of light here, but the one that you're thinking about is just a LED Ikea's bulb rolled into a poster to make the "tunnel", then it's strengthened during the photo processing.

Michał Kubalczyk haha you might be right :P
jokele The shadows and light beam... Great! 32s - What light source did use?
