One of the images I posted last week was from Eyjafjallajökul, shot during the Iceland PODAS. Here is a video by Sean Stiegemeier from the eruption in 2010. You may find Seans comments on the making of the video on Vimeo.
As I have mentioned earlier, in this day and age old techniques like wet plate photography seems exotic and alluring. Perhaps it is the flaws, or uncertainty of the process, which lends the images a quality closer to a work of art than a photograph. Here is another example I found on Vimeo. Long exposure are required, so note the supports which are meant to help the model keep still and in position.
A nice example of how to use typography to underline the message.
In the age of digital photography old techniques like wet plate photography seems somewhat exotic and archaic. I guess wet plate photography is challenging even with moderate sized plates, not to mention the large plates Ian Ruhter is working with. You will find more examples of his work on the website ianruhter.tumblr.com
Water and electronics does not strike me as a perfect combination, but the artist Antoin Fourneau and Digitalarti Artlab has made a LED panel where the LEDs light up when water is sprayed on the panel. Read more about it at the thecreatorsproject blog in their blog entry "Water Light Graffiti Lets Users Create LED Art With A Water Gun" (The video is posted on Vimeo by Digitalarti.)
