wow, nice ascii art indeed! :) since I've seen a few people ask about this and some people suggest drawing lines on the camera itself, I figured I'd take a picture of one of my cameras that I did that with. It helps to do what Jeff is describing when you actually have the lines drawn on the camera. You can get your eyes right down at the "eye-level" of the camera and follow each line out to where the edge of the image.
http://www.rahji.com/images/composinglines.jpg This camera is made of black foamcore and the lines were drawn with one of those flourescent yellow "gel pens" that they sell at cash registers in stores. That patch in the middle is where the pinhole is. If you do this, don't forget to take into account the thickness of the camera "wall" .. in this case, the camera was made of .5 cm thick foamcore so the lines in the upper left of the picture, for example, don't actually touch since they're each started .5 cm in from the end of the camera. I hope this helps! Rob > Top view looking down on camera. F line is the plane. B is area inside > your bellows. P is pinhole, with lines extending in the space.
