"Film d'essai" (test film) of my newly-arrived FOCA Universel "R", a French range-finder 35mm camera of the 50's.
The camera was loaded with a Fomapan Creative 200 36-exposure film. It was exposed for 160 ISO (that appears to be the real sensitivity of the film given the technical data provided by FOMA) using an Autometer III Minolta light meter fitted with a 10° finder. The Oplarex lens was equipped with a Foca AUV push-on 42mm protective filter and a generic cylindrical shade hood.

After exposure, the film was revealed using Tetenal Ultrafin Liquid developper at dilution 1+20 and 20°C for 7min30. The film was then digitalized 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.
Barrel racing is a high speed, athletic event that requires precision and timing. Barrel racing is primarily an event for women. Cowgirls and their horse will attempt to complete a clover leaf pattern around three barrels in the fastest time without knocking over any barrels.
The clover leaf pattern is three barrels set in a triangle formation, with the cowgirl’s being able to use either the left or right barrel as the first barrel of the pattern. The cowgirl’s run is timed by an electronic eye (a device using a laser system to record times). The timer starts as soon the cowgirl and her horse enters the arena, and will end once the pattern has been completed and the cowgirl and her horse exists the arena. The run time is dependant on several factors including arena ground conditions, the horse’s mental and physical condition, and the skill of the cowgirl.
The cowgirl and her horse will enter the arena at full speed from the alley, turn either the left or right barrel, race across the arena to the second barrel, turn that barrel, and race to the top or third barrel. The cowgirl and her horse will turn that barrel and race back down the middle of the arena and exit the arena via the alley that they entered. If a barrel is knocked over the run will have an additional five seconds added to the final time for each barrel knocked over.
Barrel racing horses are fast, agile, intelligent and very well trained.

Most of the world's steel is made into finished products by stamping. The body, chassis, fuel tank and radiator sheet of automobiles, steam ladle of boilers, the shell of containers, and silicon steel sheet of the iron core of motors and electric appliances are all stamping processes. There are also a large number of stamping parts in products such as instruments, household appliances, bicycles, office machinery and living utensils.
Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can make workpieces with reinforcement, ribs, undulations, or flanges that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision dies, the accuracy of workpieces can reach a micron level, and with high repetition accuracy and consistent specifications, holes nests and tabs can be stamped out.
Metal Stamping Parts Common Problems Treatment
1. Bonding, scratch: due to material and convex die or concave die friction and in the surface of the parts or mold appear bad;
2. Burr: mainly occurs in the shear die and drop die, the gap between the edges is large or small will produce a burr;
3. Line offset: when the part is formed, the first part in contact with the mold is squeezed and formed a line;
4. Convex and concave: uncoiling line with foreign objects (iron chips, rubber, dust) mixed in to cause convex and concave;
5. Zigzag: due to uneven stress, poor matching of the stretching bar or poor control of the press slider, etc., causing zigzag and strain on the r-angle part of the part or the embossed part;
6. Wrinkles: due to poor adjustment of the press slider, low precision of the press, improper adjustment of the air cushion pressure, large punch or r parts caused by the edge or r parts wrinkles.
7. Other specific problems: In daily production, we may encounter situations where the punch size is large or small (possibly exceeding the specification) and the size of the die differs greatly from that of the convex die, taking into account the design size of the forming convex and concave dies, processing accuracy and punching clearance, etc.
Metal Stamping Parts Application
1. Stamping for the automotive industry. With deep drawing as the main. In our country, this part is mainly concentrated in automobile factories, tractor factories, aircraft manufacturing plants and other large factories, independent large stamping and deep drawing plants are not yet seen.
2. Automobile and other industries' parts class stamping. Mainly punching and shearing. Many enterprises in this sector are classified as scale parts factory, there is also some independent stamping plant, and at present, some automobile factories or tractor factories near a number of such small factories.
3. Electrical parts stamping factory. This kind of factory is a new industry, following the development of electrical appliances and the development of this sector is mainly concentrated in the south, such as the Shenzhen hardware factory.
4. Dy necessities stamping factory. Do some handicrafts, tableware, etc., these plants have also had a great development in recent years.
5. Household electrical appliances parts stamping factory. These plants emerged only after the development of household appliances in China, and most of them are located in household appliance enterprises.

Belfast Drydock, late this afternoon, September 13, 2012, with new name painted up.
(Formerly the Seatruck Precision.)
On Saturday June 24, 2023, I found at the photo trade exchange organized monthly by the "Maison de la Photographie", Saint-Bonnet- de-Mure, France, a new clean lens Oplar 1:3.5 f=5cm for my Foca camera's with the screw 36mm mount. This lens, with the serial number beginning by 032, was manufactured in 1947 by the Optique & Précision de Levallois (OPL) French company, most likely in its factory of Châteaudun, Eure, France. The lens was the normal. lens for screw-mount Foca's camera based on a Tessar-type formula with four lenses in three groups. The seller offered me the Foca AUV filter and I bought too an adapted DYMA x3.5 filter for the lens size (push-on filter 36mm diameter).
The filter is called "DYMA" due to the presence of neodymium in the glass giving an unusual absorption by bands in the visible spectrum. In particulier blue and yellow color ans more absorbed than the rest of the spectrum. The filter existed in two different versions with the coefficient x2.5 or 3.5.
After examination and cleaning of the lens and the filters in details, I did a test film using a Fomapan 400 exposed for 80 ISO to compensate y-the filter absorption. I used a Minolta Autometer III with a 10° finder for selective measurements privileging the shadow areas. I used my FOCA camera body PF2B year 1956 an the lens was also equipped for all the views with a Genaco metal shade hood.
Typical settings during the session : 1/100s f/8 to f/11 by this very bright and clear afternoon in Lyon, France.

After exposure, the film was processed using Adox Adonal (Agfa Rodinal) developer at dilution 1+25, 20°C for 6 min.
The film was then digitalized using a Sony A7 body adapted to a Minolta Auto Bellows III and a Minolta Slide Duplicator using a lens Minolta Bellow Macro Rokkor 50mm f/3.5 at a reproduction ratio of 1:1. The reproduced RAW files obtained were processed in LR prior the the final JPEG editions.
All views of the film are presented in the dedicated album either in the printed framed versions and unframed full-size jpeg.
About the camera body :
The Foca type PF2B (PF for "Petit Format") was constructed in France by the company "Optique & Precision de Levallois" (OPL) starting from 1947. It was manufactured in the Chateaudun OPL factory, route de Jallans, France, in 1956 among a late series of the PF2B. The factory, constructed in 1938, is still at the same place under the name of SAFRAN now producing precision devices for aerospace appliances.
The camera is normally equipped with the collapsible OPLAR lens 1:2.8 f=5cm. The focal shutter of the PF2B has timing of 1/1000, 1/500, 1/200, 1/100, 1/50 and 1/25s plus the B pose. A slow exposure device below 1/25s could be installed by the aftermarket service and was installed basically for the FOCA PF3 and Foca Universel.
