Painting with LEDs and a wiimote

Confined spaces make the picture that much more real thanks to the reflections, but at the same time that much more surreal (go figure). The picture below is named “got lost?”, because giving it a name just make it seem like it’s art.

Neighbors are beginning to wonder what are these flashing lights at night. And when there’s something strange in the neighborhood, who are you gonna call? (thanks Nicolas for the idea).

The good Dr Zoidberg did not get the proper picture he/it deserved. Now, it’s done.

Looking ridiculous

…ly fun, of course. After getting many (almost 2) questions regarding how exactly was the painting done, here is a brief dark/shaky cam video showing the whole process.

 

That is what the result looks like:

(before anyone tries to do a frame by frame match of the video with the picture, this picture was not taken on the same run)

A delicate balance

with one comment

Colors and contrast of the light paintings are highly sensible to ambient lights. It is quite difficult to find the correct amount of lighting for good rendering, when aiming at twilight to get dim natural light, the window of opportunity is very limited. Here is the best I could manage tonight.

And here is an example of how washed out the colors look if you have too much lighting around.

In broad daylight

leave a comment »

Rainy day at the beach… not much to do, and I don’t feel like waiting for the sun to go down in order to continue my little experiments. Good reasons altogether to try light painting in (almost) broad day light, meaning inside an apartment during a storm. Here’s the result, looking pretty good to me.

I’ll be on the train most of the week end, but expecting to start working on the next phase (putting all I’ve learned together) when I arrive.

Settling the details

leave a comment »

Since the liightbrsuh can be moved around, it is possible to cover wide areas rapidly in limited details or to focus on on elements to get a more accurate picture.
Testing the level of accuracy that can be achieved, it appears that the biggest challenge is that my camera only allows exposure time to go up to 30 seconds. There is of course a “bulb” setting to manually open/sclose the shutter, but you have to keep the button pressed the whole time, meaning I need assistance (thank you Amelie). Taking more time to paint does allow much higher picture quality, as can be seen in the two examples below, using a 30 seconds exposure time, and going through the whole picture for the first one, while only painting a small fraction in details for the second one (see how even otherwise subtle details like the holes in the sponge are clearly visible).


Second test uses the manual exposure for around 2 minutes of painting. In comparison, the first picture was done in 30 seconds (thanks to Simba the winking cat for lending his face to this incredibly kitch picture).

Shades of blue

leave a comment »

Seriously, why did it take me so long to think of doing that?

This pictures clearly shows:

  • that it’s nice to have shades of color and to be able to position the painting wherever necessary
  • that it definitely lacks in resolution, which can be fixed either by having a greater distance between painting and camera (but then it will taking quite a long time to paint huge pictures with such a small brush…), or by strapping together two lengths of LEDs with half a led spacing between the two, doubling the resolution
