I am very new to large format, so please bear with me. I do know about Scheimpfl ug. I also understand, that once you have set lens and film plane at the angle d esired, there is an infinite number of object planes compatible with it (in book s often drawn like a wedge). Thus Scheimpflug does not garantee that the desired object plane is in focus and some additional rule seems needed (I believe calle d the "Hinge rule").
My question is this: What is Scheimpflug good for? My technique so far is to a) focus on the background, b) tilt the lens until the foreground is in focus (and repeat procedure several times to adjust for lens extension). Am I missing somet hing?
