Photography class homework from last week: This technique is so much fun! We were supposed to play with shutter speed to show motion, and these do that, though not in the way I think the teacher expected. I was looking around online for inspiration and I discovered "light painting," wherein, in the dark, you use flashlights and other light sources to "paint" on the darkness. That first swirl photo up top is an example of that, as is the word WRITE two posts ago.
