My digital camera has bit the dust. Now I wonder how to take pictures without a camera.
Photography is an art of making images from the light field present at some particular location at some particular time. To sample that light with a lens or pinhole and a light-sensitive detector such as film or CCD is one popular means to record that light field in an meaningful and hopefully interesting way. But maybe that isn't the only means worth pursuing?
Artists have over time developed less representational ways to paint, more abstraction. We all know people who prefer paintings that are nice pictures of horses or landscapes, and don't get cubism or Kandisnky. But there's a huge part of art that explores perception, pure color fields, and so on. Fine art has gone way beyond just pretty pictures.
Has something similar been going on in photography? Sure there are abstract photographs but AFAIK all done using cameras. What non-camera means have innovative photographers tried for capturing light, and most importantly, which ones might I be able to do myself?
