Light Painting

Light Echoes, Will Help You Escape Your Friday.

Here is some eye candy for your Friday, if you haven’t already seen this. The video below from Aaron Koblin & Ben Tricklebank is a visual feast of light painting created by lasers mounted aboard a train. For an in depth look at how this was made, check out the article on Wired. If you just want to be mesmerized and escape your Friday for a bit, watch the video below.

Light Painting 24X360

This is what happens when you take a year to perfect your technique, and craft. Patrick Rochon, Eric Paré, and time code lab did just that. Over the course of 365 days, multiple shoots, and hours of trial and error, they gathered enough still images to create these wonderful light painted images.

Thrash Lab Presents Light Painting Artist: Darren Pearson.

If you haven’t heard of Thrash Lab, it is a YouTube project produced in part by Ashton Kutcher. If you get a chance, click through to the YouTube page and spend some time watching these short films. They are well shot, well edited, compelling stories that explores cultural trends and encourages creativity. A great example of what Kutcher and his crew are doing is the video below of artist Darren Pearson. Pearson is a mixed media artist that combines, photography and light painting to create his images. Take the two and a half minutes to give it a watch, and then check out some of the other videos that Thrash Lab has produced.

 

Light Painting with WiFi.

I love that Google and Babble fish translate web pages for you, but I really wish I had learned more foreign languages in school, because the source for this post was at times lost in translation.

This is what is going on here, I think.

This project by Timo Arnall, Jørn Knutsen and Einar Martinussen was designed to explore the invisible radio frequencies of ground level WiFi networks in urban spaces. The team created an image with light painting by mapping signal strength signal in time-exposure photographs. Using tall rods/antennas each containing 80 points of light, they were able to reveal a cross-section of WiFi networks present in the urban environment. The whole process was carried out using a  photographic technical called “light-painting”.

This was originally done for the 2009 film `Immaterials: the Ghost in the invisible Field’ which probed the edges of the radio fields that surround RFID readers and tags in the world. It also began as a series of investigations into what Matt Jones richly summarised ace `Immaterials’.

While the team was mapping out tiny RFID fields, they wondered what it would Be like to apply their light painting process to larger-scale radio fields given off by Bluetooth, WiFi, GSM and 3G. What they ended up building was a huge architectural light painting apparatus that could map out and city-scale Wifi networks.

We built a series of WiFi measuring rods/antenna,  each containing 80 lights that respond to the Received Signal Strength (RSSI)for a particular open WiFi network.The antenna arrays were set up in urban environments and shot with time exposure techniques to reveal signal strength, and Wifi fluctuation. The cross-sections represent a year of WiFi signal strength, and graph RSSI fields across physical space. The result is an abstract image and video.
