WYISWYG – bullshit. It’s not working for me. This programm lightpaintlive is just not working for me. I tried it with my webcam, i tried it with a Canon 7d connected as a webcam, and still can’t get a solid light line with it. The idea is great, but…. You can see some of my attempts:
I think there is some problem with fps, it just can get the light normally. I tried different settings, but still nothing…
Those two are the only result 🙂
I’ve had a Cultural and Contextual referencing course last semester and wrote an essay on Banksy. This gave me an idea to try light painting with stancils. I’ve found some examples, that other people did, like these:
Also, check out this page – LIGHT PAINTING STENCILS BY FABRICE WITTNER.
I’ve tried simple stenciling, it works pretty good:
New techonlogies bring new ideas. Found this great device on eBay – Digital Multi-Function (Lightning Sound Laser HSS) Trigger. Some techical info below:
This is a digital multi-function camera/flash trigger device that can responds to lightning, sound, laser (or any light source shining on its sensor), and external trigger event such as a switch, X-sync signal from camera etc. It also has the capability to sychronize a non-HSS (non high speed sync) flash with high speed sync signal up to 1/4000 .
Highly configurable with 32 levels of sensitivity and delay of 0 to 999.999 seconds for each individual mode (lightning, sound, laser/light, external)
High sensitivity, though it is adjustable from 1 to 32 levels of sensitivity, when sensitivity is set to maximum, it can detect a sigarette lighter two meters (6 ft) away in a dark room. For sound detection, at max level, it can detect a button (US penny sized) dropping on floor.
Simulated second curtain flash trigger with External mode. This is convenient for many Canon users where it is very difficult to do off camera second curtain flash trigger.
For proper freezelighting you will need some more stuff. First of all, you will need a Remote Shutter Release for your DSLR camera. Why will you? Because it controls the shutter release time (Thanks Cap!). On my Canon 6d, maximum shutter release time is 30 seconds, but this device can give you much more in a B (bulb) mode.
After getting the flashlight i’ve decided to run a few test, trying to draw something. Here are my first works:
After studying a diversity of light tools available on the market I’ve decided to try old school flashlights. I found and ordered on eBay two Vintage Viet Nam era Fulton mx-993/U military flashlights.
You can order it on Ebay, here is the cheapest I found. There are few modification of it, but I choose the “Light Saber” 🙂
If you buy original package (there are new items on market, from old stocks) you get:
To power it you will need two D battaries. There is a switch on the flashlight with 3 operating positions: off, standby, on. In a standby mode you can turn it on and off, pressing the small button on the switch. This button is very usefull for light painting.
Enjoy!
Étienne-Jules Marey and Georges Demeny first met when Demeny enrolled in a physiology course being taught by Marey. The soon became close associates. Together they established a programme of research which was to lead to the creation of the ‘Station Physiologique’, which opened in 1882 in the Bois de Boulogne. Marey and Demeny developed several photographic techniques to study the movements of everything from humans to horses.
In 1889 Demeny attached incandescent bulbs to the joints of an assistant and created the first known light painting photograph “Pathological Walk From in Front”.
Here are some sample images, that inspired me to work on this project.
All images in this set were created using light (mainly color flashlights). Webcam + self-made Actionscript software instead of camera. No shape or color alterations (except mirror effect), completely drawn by hand. Some of the late images (with more than 4 reflections) were created using a real kaleidoscope.
I want to produce light paintings (freezelight). To do so I’ll need to have a digital camera with configurable shutter speed and ISO, a tripod, light paintings processing software (not a must have) and different light sources. My inspirations were these art works.
The artist was using self-produced software to be able to draw the paintings step by step and reflect/mirror them.
Since this software is not available for others (I tried to contact the author, but got no response yet) I found a simpler version of it. It allows you do the step by step light drawing, but I’ll need to do the mirroring myself, which is obviously not a problem.
