The Bourget lake, Savoie, France, is the largest natural Alpin lake in France with eighteen kilometers long, also call the French Lake Riviera.
I went for a photo walk to Le Bourget-du-Lac, a charming resort place located at the south shore of the lake. For this occasion, I brought along my Foca Universel "R" loaded with a 36-exposure Rollei Retro 80S (Agfa Aviphot 80) film. The Rollei Retro 80S black-and-white film is a super-panchromatic film further sensitized to the near infra-red (760nm) used for aerial photography.
The FOCA camera was equipped with the Oplarex normal lens 1:1.9 f=5cm with a FOCA Yellow x2.5 42mm push-on filter for all the views.
I exposed the Rollei 80S film for 32 ISO instead of the nominal 80 ISO to compensate the filter absorption. I used a Minolta Autometer III with a 10° finder for selective measurements privileging the shadow areas. For all the views the Oplarex lens is also fitted with a generic Genaco metal shade hood.
Typical settings filter during the session : 1/100s or 1/50s f/6.3 to f/9.

After exposure, the film was developed using Adox Adonal (Agfa Rodinal) developper at dilution 1+50 for 14min at 20°C. The views were then digitized at 24 MP using a Sony A7 body fitted to a Minolta Slide Duplicator installed on a Minolta Auto Bellows III with a lens Minolta Bellow Macro Rokkor 50mm f/3.5. The RAW files obtained were processed without intermediate files in LR and edited to the final jpeg pictures.
All views of the film are presented in the dedicated album either in the printed framed versions and unframed full-size jpeg accompanied by some documentary smartphone Vivio Y76 color pictures.
About the camera :
The Foca Universel "R" is the late series (circa 1956-1962) of the Foca Universel 35mm range-finder camera appeared in 1950 and produced until 1956. The Universel model of FOCa was fitted with a bayonet mount instead of the 36mm screw mount of other Foca PF (PF standing for "Petit Format"). Foca camera's were constructed in France by the company "Optique & Precision de Levallois" (OPL) in the OPL factory of Chateaudun (Eure) starting from 1947. This factory still exists under the name of SAFRAN a French company producing aerospace devices and systems. This exemplary of Foca Universel R was likely manufactured in 1959 or 1960.
The camera is equipped with the collapsible OPLAREX lens 1:1.9 f=5cm with the OPL bayonet mount.
