Testing a 35mm Super-Takumar lens in Beulah Cemetery and around Vicksburg with Tri-X film

Kansas City Southern railroad cut between Belmont and West Pine Streets, Vicksburg.

Sometimes, really inexpensive things prove to be fantastic. In a recent fit of GAS (Gear Acquisition Syndrome, suffered in varying degrees by all photographers), I bought an early-1970s Asahi Pentax Super-Takumar 35mm ƒ/3.5 lens. It was only $45, so not much of a gamble. Mine is single coated (meaning one layer of anti-reflection coating on the elements) and predates the Super-Multi-Coated versions that were introduced around 1971 or 1972. All share the same glass formulation of 5 elements in 4 groups.
This lens fits my wife's 1971 Pentax Spotmatic camera. These were elegant, reliable cameras made by the Asahi company and marketed in the USA by Honeywell. They used the Practica M42 screw mount for the lenses, and many companies made lenses that would fit. Camera-wiki lists many of these M42 lenses. But the best mechanical and optical quality usually were the Asahi ones. Many photographers considered the Pentax lenses to be better optically than equivalent Canon and Nikon versions in that era. The thorium-element 55mm ƒ/1.8 Super-Takumar is one of the best 50s ever.
Well, my new-old 35 is an amazing performer! It is sharp and and has beautiful rendering. It is a retrofocus design, meaning it is designed to fit far enough away from the film plane to allow room for the mirror in a single lens reflex (SLR) camera. My 35mm ƒ/2 Summicron-M for my Leica is probably sharper and more contrasty, but it is not a retrofocus design and is a $2000+ lens, not $45. Below are some examples from in and around Vicksburg.
The cottage at 1900 Martin Luther King, Jr., Blvd. had a fire and will likely be torn down soon.
2228 Martin Luther King, Jr., Blvd is a mid-century wood duplex. It is right next to Beulah Cemetery and is empty; status unknown.
Historic Beulah Cemetery is located at the very end of Martin Luther King, Jr., Blvd., right next to the Vicksburg National Military Park. The cemetery was formed in 1884 and is still in occasional use. 
"The cemetery is the final resting place for over 5500 members of the most prominent black families in Vicksburg, including ancestors of almost every native black in the Vicksburg area. The cemetery documents the existence of generations of people for whom otherwise there might be no surviving material available." 
The site was overgrown and largely neglected for decades, but an AmeriCorps team and other volunteer groups cleaned the site, and it is now on City of Vicksburg maintenance. It is a quiet place for photography. For more information, see http://beulahcemetery.org.

Photographs: Honeywell Pentax Spotmatic camera with the 35mm ƒ/3.5 Super-Takumar lens. All photographs were tripod-mounted.
Film: Kodak Tri-X 400, developed in Kodak HC-110 developer.
Light measurement: Gossen Luna-Pro SBC light meter.
Scanner: Plustek 7600i using Silverfast Ai software, scanned at 3600 dpi.

I would be glad to hear from readers who use classic cameras.

Cement Silos of Redwood with Fomapan 100 Film

In 2010, I wrote about the deserted cement silos in Redwood, Mississippi. They are still abandoned and loom up above Hwy. 3 in all their concrete ugliness. It is a good site to test film, and I returned to test Fomapan 100 Classic film in my Fuji GW690II medium format camera. The tracks lead to the International Paper mill just to the north.
The brush is pretty thick and it is hard to reach the silos from the former work yard on the west. This photo is not completely sharp because of camera motion.
A hulking ruined concrete mass is in the work yard. Did they pour unwanted concrete into some sort of bin?
This is a loading dock on the railroad side of the main building. Being winter, there were no obvious snakes, bats, or poison ivy present.
This is one of the chutes that would dispense powder into trucks. This was a 4 min. exposure at ƒ/11. The light meter indicated 30 sec. at ƒ/11, but I knew that to adjust for the film's reciprocity, I should use 8 times the metered exposure. Reciprocity failure means that in dim light, film no longer responds in a linear fashion to increasing exposure time. Most film is linear in the range of 1 sec. to 1/1000 sec., but if you are in the range of many seconds or minutes exposure, you need to multiply the light meter setting many times. A Wikipedia article describes the phenomena, or contact me if you want to do some film photography and I would be glad to help.

Film: Fomapan 100 Classic.
Camera: Fuji GW690II with 90mm lens.
Development: Xtol by Praus Productions, Rochester, NY
Scanning: Minolta Scan Multi using SilverFast Ai software, 2820 dpi.

Vicksburg Decay 2016 with Fomapan 100 Film

Mercy Hospital, Vicksburg (currently unused)
This is a three-part experiment: a new film, a commercial laboratory I had not tried before, and new scanner software (I know, I know, too many degrees of freedom).

Experiment 1: A few months ago, I read some highly positive reviews of Adox CHS 100 film, a classical fine-grain black and white film. While in Berlin last September, I stopped at Fotoimpex (a real film store) to buy some, but they were out of stock. The sales agent suggested I try Fomapan 100 Classic, a similar film made in the Czech Republic. Fomapan was established in 1921, so it has a long history of making sensitized materials for the photographic industry.

In December here in Vicksburg, during some overcast days with soft light, I tried a couple of rolls of the Fomapan in my big Fuji GW690II camera (this is a medium format rangefinder camera that takes eight 6×9 frames on a roll of 120 film). I like days with soft light when an exposure will reveal details in the shadows, such as under porch roofs. My usual practice is to overexpose and underdevelop to soften the contrast, so I exposed the Fomapan at EI (exposure index) 64.

Experiment 2: I did not have time to develop the film at home, so I sent it to Praus Productions in Rochester, New York. Praus developed the film in Xtol developer at N-1 (pull one stop), as I specified. The negatives looked pretty good, a bit dense but with full exposure range. Next time I will try EI 80 or 100 to just slightly reduce exposure.

Experiment 3. The Minolta scanning software that came with my "antique" Minolta Scan Multi scanner was pretty kludgy and was low resolution on a modern big monitor. Surprisingly, the German company Lasersoft Imaging still sells a version of their Silverfast Ai software for the Scan Multi. I thought the price was outrageous, but a Christmas 25% sale made it a bit more palatable, so I bought a license for Ai. It runs on my Windows 7 computer and correctly controls the scanner. Result: major improvement over the Minolta software with far more options for film profiles. Note: many photographers use Vuscan software, but I could never get it to work.
Zollinger's Hill Road
Results: Well, I am pleased. These are beautiful full-tone negatives. They have similar grain to Kodak Tri-X, which this reinforces the classical B&W look (which can't be simulated with software). The photograph above of Zollinger's Hill Road almost looks like the bushes are covered with frost, sort of a hidden garden. Click any picture to enlarge it and see the texture.
This is Marcus Street near where it intersects Confederate Avenue. The house is no. 1620. This was a 1/2 sec exposure at f/22, with fill flash to add some light on the tree trunk.
This cottage at 1630 Marcus Street is empty.
These steps are next to 1630 and lead down to Ethel Street. During summer, the jungle mostly engulfs the steps.
Martin Luther King, Jr., Blvd. is the former Openwood Street, leading from downtown east to the Vicksburg Military National Park. It is one of Vicksburg's older streets and is lined with historic cottages.
The cottage at 1900 MLK, Jr., Blvd. suffered a fire.
No. 1826 MLK, Jr., Blvd. is a 1920s or 1930s cottage, now empty.
No. 1832 is a duplex partly sheathed with the concrete material shaped to look like limestone blocks.

In the future, you will see more examples of this Fomapan film as well as the ever-dependable Kodak Tri-X. In the USA, you can order Foma products from Freestyle Photographic Supplies in Los Angeles. Support companies that sell film, and take pictures with film. Really, it will make you a better photographer.
