Using your planning document to help you, take a picture of your figure in the first position. Then, move the figure a little bit, and take the next picture. Move it again, and take another picture. Make sure you don't move the camera AT ANY TIME, and only make SUBTLE MOVEMENTS to your scene and figures each time. Carry on moving the figure, taking a picture every time you do.
TIPS:
You can change the scenes, add more characters, and once you get the hang of it, you'll be having fun, and be great at it! The only thing you need is PATIENCE. Stop-motion can require hundreds, if not thousands of pictures. So, have fun, practice and be patient.
Questions to consider:
As photographers, you should take as many pictures as possible for the video editors.
If you're going to use a certain app to shoot the pictures, make sure you negotiate with the video editors first.
