settings for canon rebel eos

Hello animation fans,
I am using the canon eos rebel 1000D with istopmotion. I do not mind the lack of live view, although I look forward to it in the near future! What I would like to know is what are the “in camera” settings for the Canon rebel. Should I be using the highest quality image or does istopmotion take any still and render it at a certain quality? Thanks for any advice you can share!

iStopMotion is scaling the images to the movie size anyways and storing them in a uncompressed format. If you choose a smaller size in the camera you will see that the images get transferred faster from the camera to iStopMotion.
