A drop of highlighter ink in the center of a purple flower. The lighting was done by 2 UV flashlights. As the ink was so bright, I had to use multiple exposures and blend them into an HDR image. I used Adobe Lightroom for the basic blending and adjustments and Photoshop to clean the images from the many dust particles (which were so many).
