Andrea B. Posted July 26, 2018 Share Posted July 26, 2018 Fluorescence is always an unexpected delight. This UVF melon looks quite frosty. Are you using a diffuser on your Convoy? Your light painting looks nice and smooth. It is so easy to miss an area or to create hot areas when light painting. Takes a lot of practice, for me anyway. Link to comment
Adrian Posted July 26, 2018 Author Share Posted July 26, 2018 No, just guess work! What diffusing material could you use? Link to comment
Andy Perrin Posted July 26, 2018 Share Posted July 26, 2018 Love this. The dark seeds are interesting. Wonder what UVIIF would do. Link to comment
Andrea B. Posted July 29, 2018 Share Posted July 29, 2018 Diffuser -- once Klaus gave me a small piece of plastic which was slightly "pebbled", for lack of a better term", to fit over a 365nm Nichia UV-Led. This worked to decrease the typical hot spot. Of course I have absolutely no idea what kind of plastic that was. You can search on an optics site for diffusers to see what is available. Edmund Optics has some I think. Link to comment
