The title says it all. http://42graphy.org/science/2013-04-physfest/demos/_IR04201.html
I don't remember if I had shown this one earlier. I thought I did, but I cannot find the photo on the website or the message that had sent. I am going through the photos taken at the Physics Festival earlier this year. If you are science-image-curious, - take a look at this plasma discharge: http://42graphy.org/science/2013-04-physfest/demos/_IR04476.html Larry, this is not moire, even though it is shot with K-5IIs camera: http://42graphy.org/science/2013-04-physfest/demos/_IR04850.html Rather, it is a standing wave - this is what happens when you generate sound by sliding your finger on the glass. Larry, - you may also want to see how I used the 8mm fisheye with this one: http://42graphy.org/science/2013-04-physfest/demos/_IR04821.html and surrounding photos.
