I would love to start playing around with long exposure photography, more specifically light painting. I sadly don't have any camera except the iSight built into my Macbook Pro and my mid-range Android phone (I'm in college. Money doesn't really exist for me). Does anyone know of a way to take long exposure photos using either a Mac or a good Android app that can?

    One of the problems with long exposure is that it requires a very firm surface. Also, it requires a sensor without alot of noise. Both of those are going to be very difficult in a phone or a macbook. A camera has a screw to connect it to a tripod, making the problem easier, but I don't know how you'd do it with a phone... Hmmm. – PearsonArtPhoto Jan 29 '11 at 22:29
  • I have to agree with Pearsonartphoto, your limitations on hardware are going to make it difficult to do. It may help to define what you mean by long exposure as, for some, it's as little as a fraction of a second, for others it's minutes or hours. – John Cavan Jan 29 '11 at 22:41
  • The two platforms you're asking about are so different that I think this would be better as two separate questions. – mattdm Jan 29 '11 at 23:24

Looks like there is an app that allows you to control the exposure and shutterspeed of the iSight:

  • Unfortunately, the shutter speed setting is only available on external iSights. – Evan Krall Jan 30 '11 at 0:31
