I have read a copy of the Addendum to Focusing the View Camera by Merkilnger, ho wever I am confused as to how you actually calculate the height of the lens abov e the plane of sharp focus ( "J" in his diagrams). I appreciate that you measure the height of the lens above the ground, but how do you measure the bit beneath ?????
There is probably a very simple explanation but it has me stumped !!
