Using a free camera

- One of the main advantages of using…a target camera is that the horizon line…will always remain level, as long as the camera…and it's target are more or less level.…So we can see that better, let's make the grid…larger in the perspective view and the camera view.…Right click on any one of the snaps icons…and go to the home grid and I'm going to…set the Perspective View Grid Extent to 500…and press "enter."…That'll extend the grid out farther.…Additionally, you can make the horizon line visible…in a camera view.…Just select the camera, go in to the Modify panel…and you'll see "show horizon" and that's really helpful.…

If you move that camera or it's target around,…the horizon line will always stay level.…It's hard wired to do that,…however the down side of that is that…if you need to make the camera look straight up…or straight down, the behavior of a target camera…is going to be a bit weird.…We can see that here in the perspective view.…If I move that camera so that it's looking straight down,…it's starting to swivel around and do strange things,…
