3dlightpainting

We’ve shared a few pretty cool cross-section light painting projects before, but none of them were ever very... shall we say... cheery. Both projects -- 21:31 and Andy Leach's hologram photo -- were created using the same eerie video of human slices from the Visible Human Project. But for those who wanted to toy around with cross-section light painting and re-creating 3D light objects in their photos, that’s all they had.

Well, not anymore. Photographer Hugo Baptista has put together a Vimeo group called "Cross Section Objects for Light Painting". It contains a number of videos that you can load onto your tablet or smartphone and use to create 3D light painting objects.

3D light painting can be done by using a 2D image rather than a single point of light. In the past, we've shared creative examples of iPads being used in this way to light paint everything from ghostly figures to creative animations.

These ghostly figures you see in these photographs weren't Photoshopped in, but are purely done through light painting. If you remember the creative 3D light painting technique using an iPad that we shared a while back, Croix Gagnon and Frank Schott took it a step further and put a slightly morbid twist on it. For their project "12:31", they "painted" using a laptop and an animation showing cross-sections of a human body!

After photographer Ross Ching came across Dentsu London's creative 3D light painting technique with an iPad, he decided to give it a try, combining it with timelapse photography to make a music video for "I'll Try Anything Once" by The Strokes (seen above). The app he used was Holographium, which you can pick up for $5 from the app store.
