Hi,
In the old days it was easy and critical (exposure wise) to measure the scale of reproduction when shooting with a view camera. The scale of reproduction was measured from the ground glass with a simple ruler.
Sinar has a document on their web site which states min., optimal and max. scale of reproduction factors for Sinaron lenses. My question is how you measure it? I have a P2 with Phase One sliding back. Is there a way to measure scale of reproduction from capture one or do I still measure from the ground glass with my Calumet ruler?
