Let Ther Be Light

At work, we use a high-speed camera to photograph our metal printing process. At 60,000 frames per second, it is an excellent resource for understanding what is going on. Due to the extremely bright deposition zone (white-hot molten metal), the rest of the image is underexposed so much that it is not visible. To overcome this limitation, I thought I would try using one of my camera strobes to illuminate the entire scene. The idea worked perfectly allowing us to see the contact tip and deposition line for the first time albeit for just a couple of frames.
