No, this is, of course, not the Linhof/Schneider/sheetfilm. This is the Ernemann Bob 0, with the Detektiv Aplanat 6,3 125mm on definitely not flat 120 in a 9x12 space. But I love my almost-centenarian not as an object, but as my inspiring workmate.
40+ Years old! Ilford Selochrome 620 in Rodinal and (almost) no problem at all. Well, some dark wrinkles here and there. And look at that 70+ years old Tessar, so much better than the Retina-Xenon. Wòw!
Kodak Duo (means: two 4x6 on one 6x9) 620, Carl Zeiss Tessar 3,5 75mm (around 1938)
1914 - Der Kaiser launches the Great War, and Ernemann brings "the smallest vest pocket folding camera ever put on the market". With unbreakable ground glass (celluloid) so it can be sent as "Feldpost", for nice pictures from the trenches.
For the shown picture I used Fomapan100. Caught a mouse in my wet-table before developing in Rodinal (the film, not the mouse). The Achromat shows a great post-expressionistic coma.
It seemed so nice: on my stereo-Iloca left a blue and right a red filter and hey presto: colour pictures. Well, not thàt easy. Because Fomapan 400 isn't very pan; hardly sees the reds, but almost blind for greenish-blue! So let's call it Fomakitrin.
The picture above doesn't work in my Underwood&Underwood (1907?) because it is not stereo - but laid on top of each other, well, it seems not bad, lacking the green of course. Not bad at all...
Yes, it's a TLR, and no, it's not a Rolleiflex. Definitely not. My first, in 1964, lasted a week, but Mr. Wijnen from Fotopost gave me another one - without any question. In 1983 I bought my third Lubitel, not bakelite, so not the real thing. Nostalgia.
