Silvestri's mysteries...

[mario_mab]

Hello,

Does anyone have information about the Silvestri RS 45 (6x9)?

Though, the Mod. H (6x12...?)looks interesting too.

Even in their web site there is nothing written about it, besides

that it is a metric camera, whatever that means.

I would appreciate any info.

Thank you.

Hello Mario

 

Don't know about the Silvestri, but I should inform You that a metric camera is a camera-lens combination spesially calibrated (& very expensive) to do photography for mapping/metering purposes. Typically, archaeologist, technical constructeurs sometimes use these to produce pictures where they can measure distances directly on the picture. Thus the metric camera usually/allways have a reseau-plate of glass in front of the film and with fiducial marks etched into it to produce reference marks on the film (necessary to compensate for film-shrinking/movements). As so, they are not practical for pictorial photography if they can not be converted (reseau-plate removed and ordinary film-guid inserted instead).

 

Hope this helps
