If your 30x30" camera has a bellows at least 1.5m to 2m long, why don't you put the front element of your 630mm Petzval lens and take a look at the ground glass? You will be surprised.

Yes, thank you Hugo! I really have to work more with the petzval glass. The front element works miracles! But the RR lenses in huge size balanced that incredible look between in-output quality very harmonious.
