It's not convenient at all in the workshop, those two big tripods have an enormous envergure, one is needed for the lens, the other one for the camera (the stripped below in the center).

So, can I see something on the Fresnel lens of the camera ?

After trying to focus on something I decided to open the window, not so clean, and...

Fantastic !

That's about 12 meters away from the film position.

Looks sharp, but with blur on the highlights, typical of an uncoated lens mid XX century, not really GOOD, but certainly interesting.

But, wait a minute, why is that image round ?

A big lens like that must have an image circle far bigger than the 4 x 5 inches of the camera fresnel viewfinder lens...

That's what I can see thru the window, and it's not round shaped.

Ok, there's a rond thing in the camera.

The marvelous Copal/Sinar shutter has a round opening of something between 8 and 9 centimeters, more than enough for the average large format lens, but quite too small for this one.

Yes, I like it like that ! (the viewing with a large format camera is upside down).

Allright, let's go out and take a picture.
