I started using a Tachihara 4x5 camera recently and use BW/C41/E6 film. From what I read in an old post, sliding the front standard with the lens on the focus board with the markings "1,2,3,..." (see Photo below) will get me to my infinity mark (my 150mm lens = ~ Position "3.5"). Then I try to fasten the front standard in that position. Is there a technique to allign it on the Position "3.5" so that left and right are parallel ? It seems to me that because there are no hard stops that it creates a slightly shifted lensboard each time I set it. Please correct me if I am doing anything wrong, I would like to know more on how to set it up properly. Apologies if this seems like gibberish, I find it somewhat hard to write about. Any help is much appreciated!
