Last week we featured some “sound painting” photographs by Martin Klimas, captured by using a speaker to vibrate paint. Here’s a video tutorial by some Arizona State University Polytechnic students demonstrating how you can do your own “sound painting” photos. They use a thrift store speaker covered with a garbage bag and some Crayola poster paint.
Want to made giant prints of your tiny phone photos? Instead of doing the enlargement purely with Photoshop, Photojojo suggests using a scanner for high-quality enlarging. Simply resample the small photo at 360dpi, print it out on high quality matte paper, and then re-digitize it using a scanner at 360dpi and the print size you want. It’d be interesting to see a side-by-side comparison of this technique versus simply resizing in Photoshop and printing that image directly.
Wondering whether or not the shutter speeds on your camera are accurate? Instead of taking it to a shop or buying expensive testing equipment, you can use an old television or CRT monitor as a simple shutter speed tester!

For a more technical explanation and tutorial, check out this article that appeared in a 1967 issue of Popular Science.
