Currently studying the "book" and shooting polaroid in order to learn how to use it.
I got the camera almost 2 month now, figured out most of the movements and what those knobs do. Did few test shot, blowed away by the details and tonality in the negative (when the camera didn't shake and the focus was right). But I had quite a few bad negatives too.
Tilt, swing, shift, rise, fall, bellow factor, exposure compensation, level, cock shutter, close shutter,...... and, most important, don't forget to pull the darksilde! It is a totally different process compare to shooting 35mm. Not so sure my little brain can handle all that, but I enjoy doing it.
Good luck Mark, you will get a hang of it.
