I want to start the thread by saying that at the moment I am researching the possibility of moving to large Format 4x5
So far, my camera choice looks as though it's going to be the Chanonix 045N-2 and a 150mm lens.
I like to photograph a variety of subjects including church interiors, exteriors, landscapes and still life.
My question is regarding bellows extension for still life.
From the research I have done, I understand that to obtain a 1:1 magnification, the bellows have to be extended 2x the focal length so in the case of a 150mm lens the bellows needs to be extended 300mm.
Is there a way to work out how far from the subject roughly the camera has to be as shown in the sketch below. The reason for wanting to know this is because the area I have to make still life photographs is quite small.
