    Set up an object on a table that has a well defined vertical edge several feet from the camera and line it up with another vertical line such as a window frame across the room (maybe 20 feet away). Stop down as far as you can to maximum depth of focus.I take two photos, one with the object on the far left side of the frame, and then swing the camera around and take another with the object framed on the right side. Then, using the digital display on the back of the camera, I zoom in to inspect the images to see how far left or right the misalignment is and then adjust the camera position and repeat the process. When both images have the same appearance, I lock it down and take note for that specific lens. It usually takes about 6 attempts and 10 minutes.By using a window frame,the misalignment will be seen as a light leak in the gap between the object and the window frame. When the sliver of light goes away, you have the perfect nodal point.

    Thanks for getting back to me. One more question: How were you able to get find the nodal point of your camera & lens with such precision? I am using a gigapan epic pro and Im not sure about how to precisely calibrate it.

    The distance was about 12 inches. It was stitched with the gigapan stitcher, but I have had lots of success with Photoshop as well. The lighting was a single softbox and strobe directly overhead.

    Amazing shot!! Great lighting! How close did you get to the skull? What program did you use for the stitching?

    Great detail Russ, I hope you are planning to do the frontal shot.

    The only way that this can work is if the camera is on a calibrated pano device in order to control parallax. In this case, it was a Panosaurus because the gigapan is too small for the Canon SLR. Macro is absolutely unforgiving in parallax errors.

    That would be a great photo for an e-text book and for a power point lecture. Was the a hand-held shot or did you have to use some tracks?

    This was 14 shots (7x2) with 100mm Canon Macro
