Want to make a stopmotion with an SLR but need to rotoscope or lip sync? For about $20 you can do just that WITH ANY SLR CAMERA!

For the eye piece, go on eBay, search "Eye Cup Nikon". Get a circular eye piece, don't spend more than $6 because they might be "too good" and you won't be able to take it apart! I noticed there are a few on ebay that do not have the metal piece to attach to the camera, so watch out! http://bit.ly/gk1FiI
