I went to Death Valley with my friends this past weekend. It was an overwhelming trip. After watching a beautiful sunset I decided to do some light paintings. Most of them are 30 seconds exposure and painted with the iphone 4 flash light. I explained my technique in one of the earlier posts. It was super fun. (Shot with Nikon D7000 18-105mm 3.5-5.6)
This one is done with a different technique. The letters are extruded with the iPad screen. There is an app called holographium. You type in a word and the app cuts the word into slices and plays back the individual slices over time. Now if you use a long exposure in your camera and move the iPad slowly you can extrude your text in space. Pretty amazing.
And last but not least this is something I did with my co-worker. It's the same technique like above but in this case it's a real human body that was cut into slices. You can find the video and the process here.
This is a lot of fun and I want to experiment more with it. (Canon 5D Mark II with 24mm 1.4 25sec exposure)
