I used a remote control, which can be seen next to the mini tripod and a disco light with 6 different colors. I set it to the highest speed so that all colors can be seen in the finished image.
I took about 150 images of this scene until I found one that I liked.
This is PSOOC because I only cropped it a bit to lead the focus to the cap in a better way.
Here is another shot I did in this series but I prefered the canon one at the end so I will only publish this one here:
This way I also want to thank all the studious flickrites who are supporting me with their faves, comments, mails and their critique.
I really appreciate your feedback!
