Step 8: CAMERA SETUP.
Here's the thing. You need a camera to look at your stuff and take pictures. And I guess you could hold it in your hands, but the shake, moving position, and so on would reall complicate the post-processing of your images. What you need is a stand to put your camera on. We used a tripod, but of course you don't really need a tripod. In fact, there are dozens of tripod-like objects on Instructables. If you don't have a tripod, check 'em out.
Ideally, you want your camera to be facing the page so that the screen on the back of the camera is parallel to the page. If things are straight-on, there is less correction to do in software. It's worth playing around a bit to get your camera perfectly positioned. Once you have it set up, you might find, as we did, that it's ready to fall over! In this case, tape the back leg of the tripod to your table.
