Alright, heres what you gotta do.

1. you need a camera that has a burst mode, and depending on your sequence you'll want at LEAST a 2fps drive mode.

2. set up your shot and shoot the subject, besure to get entry shots and run off shots to fill up your picture space.

3. open all of the pictures into photoshop and chose the first picture as the "background". have your layer pallet open. drag the "background" layer onto the "new layer" button to make a copy of the background. delete the original.

4. now, one by one, you'll need to copy each picture one by one and paste it into the "background" picture, they will fit perfectly over the original. after you've added your first one, add a mask by either clicking on the mask button in the layers pallet, or, by going to the layer menu and down to "add layer mask --> reveal all". then, with your paintbrush tool selected and the colour black selected, paint over the top layer where you want the bottom layer to show through.

5. repeat this for all of the pictures in the sequence!

DONE!!!

or a webcam ,you set it to take a pic every second,then open your animation program and paste each pic in to the animation frame by frame
