I have a single cell of an old Taylor Hobson lens that I have mounted on a copal 3 shutter.It has a nice bokeh and works well.I have guestimated a focal length of about +/_ 150mm.
My question is how do I determine the f stops so I can use the shutter consistantly and be able to repeat or calculate exposures.
Thank you everyone.
