For regular movies and films, the camera takes videos - it captures live action - so it doesn't really matter if the camera is bumped a bit while recording; it's natural. But that doesn't work necessarily for stop-motion, since it captures still images.
One small little movement of the camera, just one little tap that moves the camera about a millimeter, can ruin an entire scene. Here's a demonstration of this happening:
You don't really notice it in the still pictures, but when they are played consecutively as an animation, the one odd image stands out.
This is why you can't just take pictures clicking the button on the camera either. You'll move the camera while you try to take images! So then... how exactly do you take pictures for stop-motion animations?
Simple: you need a program that takes the pictures for you.This is called tethered remote shooting.
There are many stop-motion programs that has a tethered remote frame capturing system, but there only a few cameras that are compatible with tethered remote shooting. These are the cameras I've mentioned earlier - DSLRs.
There are many available tethered remote frame capturing programs:
Dragon Frame: the official (and best) software for stop-motion editing and animation. Many big movie companies such as Disney uses this software for their stop-motion movies. It has the most advanced tethered remote shooting system, and the entire software costs $290 - $350.
Monkey Jam: the best free stop-motion animation software that has a tethered remote shooting system.
Basically, this is how a tethered remote shooting system works:
1. You connect your DSLR camera to a computer or laptop.
2. Open your tethered shooting frame capture software.
3. When you click the "Capture" button in the software, it also automatically takes a picture in your camera connected to your computer.
This is the best way to take stop-motion animations since you never ever move the camera at all.
