Sound good? Let's do it.
Step 1: What you need
- iPad. An iPhone or iPod Touch will also work.
- Camera with shutter speeds of 10 seconds or longer and a manual mode. Bulb mode is handy.
- An app or two
- A friend to help out. Optional.
Note: I'm sure cool stuff can be done with an Android device as well, but I don't have one. Feel free to post about any relevant Android apps in the comments.
