La Memo adquirida es una caja rectangular de madera revestida con piel sintética que es fácilmente ceñible con la palma de la mano pues sus dimensiones son de apenas unos 5x11圆,5 cm (anchura x altura x profundidad) y poco más de 330 gramos de peso (sin película). La Ansco Memo fue una de las primeras cámaras americanas que se lanzaron para competir en el incipiente mercado de los 35mm, comercializándose tan solo tres años después de que se presentara el prototipo de Leica de Oskar Barnack.Ĭorresponde a una patente de invención y diseño a nombre de Carl Bornmann, presentada por la Ansco ante el Registro de Patentes el 22 de Enero de 1922 y concedida con fecha 10 de Enero de 1928, con el número 74.211.

The dried negative was wet mounted on a drum and scanned on my Scanview 11000 Drum Scanner at 2100 dpi which gave a very large file which I then processed to my preferences in both Adobe CS6 along with Nik Silver Efex Pro 2. The whole process was carried out at 21° C. This was followed by double water washes before being fixed for 5 minutes in an alkaline fixer prior to 11 minutes of washing with repeated water changes the film was then soaked in a tray of wetting agent prior to being dried. The part A developer was introduced without a pre-water bath and was processed for 6 minutes at the F setting on the CPP2 with part B being introduced with the drum rotating at its maximum speed to enable the part B solution to cover the film as quickly as possible, this again was for 6 minutes although I did reduce the speed back to F after the first minute. The film was processed in Pyrocat HD which I used as a divided 2 bath process at a dilution factor of 1:10 for both parts A & B (part A had the addition of 5 drops of wetting agent to prevent streaking) using my Jobo CPP2 with a 3006 expert drum. I did add a degree of front lens tilt to try to have some control over the areas that would be in focus. The exposure given to the 5x7 ISO400 Ilford HP5 film which I had rated at an EI of 250 was a 1/10 second at f22.

I returned to the spot at the rear of St Budeaux Parish Church where I took my last Image on my Photostream with my Leica M4, but this time I took my Canham MQC 5x7 Camera and partnered it with a Wollensak Velostigmat 6.25' f9.5 8x10 Wide Angle Series III of approximately 90 years old which is in an old Betax 3 shutter. Negative developed in Pyrocat HD, 10 minutes standard dilution. I used a medium yellow filter, so adjusted to give an extra 2 stops: 1/2 second became 4 seconds (reciprocity) exposure at f11.5, using 8x10 inch Ilford HP5+. Yes, the negative has suffered some loss of contrast (light dispersion) and maybe softened a bit, but it was a perfectly usable negative!Ĭlick to zoom way in and see the details.

Well, I decided to mount in in the Betax shutter and see just how compromised it is. You'd look at this lens and think 'Poor thing, you aren't much use anymore, are you?!' The lens that came with the shutter is quite damaged: a wide margin of balsam separation round the edges of BOTH front and rear groups, and one of the center adhesive layers in the front group is a network of separation squiggles and lines. I recently acquired a Turner-Reich Gundlack 12' convertible lens in a Betax shutter, which in fact, I bought mainly for the shutter, so I could mount my other 12' Gundlach lens to make it more usable.
