It is actually fairly quick (with practice.) There are no degree or millimeter markings on the MT. With my new Linhof Technikardan (TK45) I have been using a measured scientific method since this camera has measure and degree markings everywhere. Focus on the near point (note measure on rail), focus on far point (note measure on rail). Subtract. Either estimate or measure (I have a little mm ruler but estimation works pretty well) the distance between the focus points on the ground glass. Divide the GG distance into the rail difference (everything is in millimeters) and multiply by 60. Set the front tilt standard to that number as the answer is in degrees. Rail focus difference is 14mm. Distance on ground glass is 70mm 60(14/70) = 12 Tilt the front standard 12 degrees. Refocus. Set exposure. Take photograph. Jim PS. Reference...
