Re: Zeiss Aerotopograph RMK and Rb - cameras
Hello C-F
My understanding is that both terms derive from the ‘Reihenbildner’, a word seemingly coined by Oskar Messter for his pioneering camera of 1915. The ever-restless and inquiring Messter came into the field of aerial imagery via Cinematography, but within a few years aviation developments led to optics used by cartographers being carried aloft in similar cameras.
With the term RBK already coined it was logical for essentially survey instruments to become known as Reihenbildmesskamera (RBMK). I think the first RBMK was the Zeiss C/1, which came on the market in 1921.
I suspect that thereafter both designations got abbreviated. All of them can, I think, be designated RbKs, but not all of them are RbMKs.
