So this is something that I see a lot in tutorials and I have never had it explained. But why should you do this or when is it suggested to use a null object to control a camera?

I use AE a lot, but for basic stuff, but I have a project coming up where I will be doing a good amount of movement. I'm going to be creating a coffee table look that has polaroids laying on top of the table. These polaroids will have video inside of them. Then I want to have a camera move and rotate around revealing the unseen sections of the table, etc.

So would I use a camera controlled by a null here? I have gone through the AE Apprentice book but it never taught using nulls as camera controls...I don't think.

Thanks! :)

I'd hook at null to a camera when I wouldn't want to fool with the actual camera controls, which yield unexpected results unless you're experienced with them.

You want to pan & tilt, the no-nonsense kind? Nothin' like a null for that duty!

There are some tutorials here that show how to move and animate a camera. Several of them show how and why using a null object layer makes working with cameras easier.

Your definitely going to want to parent your camera to a null object. Here's a link to video copilot tutorial that addressed this topic and includes a really useful plugin for this technique.
