Around Olympia with Kodak T400CN (Abandoned Films 13) (Oly 08)




Introduction


Dear Readers, it happened again. I intended to no longer use expired films because of the risks of blotches or other issues caused by old age and improper storage. But a few months ago, an eBay seller included a complimentary roll of Kodak T400CN film in an order. I loaded it in my Leica IIIC camera and tried it around town. 

T400CN was a 1990s C-41 black and white film. It could be processed in common C-41 chemistry almost anywhere on earth (such as by any 1-hour processing kiosk) and yield black and white prints. I used it a few times in the past. When fresh, it was very fine grain and high resolution for a 400 speed film. Other companies also marketed C-41 black and white films, but today, only Ilford XP2 is left. 

Kodak discontinued T400CN in 2004. The Professional Portra 400BW film was similar (or the same?) and was discontinued about the same time. Kodak replaced them with BW400CN, which I have used in my Abandoned Films series. The last few rolls were more grainy than when they were fresh, so possibly the BW400CN changes chemically when old. Of course, other factors, like the brand of C-41 chemistry, may affect the appearance of the film. Has this T400CN aged more gracefully? 

Because of the age, I decided to expose it at EI=120 rather than the original specified 400. I took the film to Photoland at The Evergreen State College. They called me after 3 hours to report that it was ready! I scanned it on my Nikon Coolscan 5000 scanner. The advantage of a C-41 film, either color or B&W, is that the infrared ISRD function can identify scratches and correct them. It is a convenience because you do not need to touch up as many flaws on the film with a heal tool. Unfortunately, this does not work for traditional black and white film. 

This was also a test of my Leica IIIC camera and its 5cm ƒ/2 Summitar lens. In the past, the IIIC suffered from a zone that was out of focus on the far right. I suspected that the film was buckling or not lying straight in the rails. I added another nylon washer on the post that pushes the film canister up into the body. The reloadable Leitz film canisters, which were common in the 1940s, may be marginally taller than modern commercial 35mm film canisters. Even if the film lay perfectly flat (which never happens in any 35mm camera), the Summitar has field curvature, so the best focus curves towards you at the sides of the frame. 

Yes, I know, this experiment had too many variables. There were too many degrees of freedom to be able to isolate contributing factors. But you readers can decide if it all worked out. Here are some random scenes around Olympia, Washington. Click any photo to see it at 1600 pixels wide.

Where did all the hail come from? Olympia certainly has interesting weather. What happened to spring?

I scanned most of this roll using 16-bit grey scale. But my Nikon Coolscan 5000 occasionally shifts to the default setting of full-color RGB (meaning 3×16-bit). I like the effect. It resembles selenium or one of the red toners. I may use this more with this T400CN film, but it would only be effective for certain subjects (artsy-fartsy stuff). 


This is a crop of the scanned file. It shows how much detail this film can capture. And this is from a lens designed before World War II! Note how this film does not have grain in the same way as a traditional black and white film. This, and all C-41 films, have dye clouds, instead.

Summary


T400CN film: I am pleased. This long-expired film was fine-grained and recorded a large exposure range. It does not look like traditional black and white film, and it may be less contrasty than Fuji Acros. But T400CN is more convenient to get processed if you have access to a photo lab nearby. Next time, I will expose at EI=100, so two stops more than the original 400. (A few years ago, I tried Ilford XP2, the only current C-41 B&W film, but did not like the results.)

The Nikon Coolscan 5000 film scanner: It is higher resolution than my Plustek 7600i. And the Coolscan has a higher dynamic range, meaning it extracts more data from the film. Also, the Coolscan does a focus adjustment with each frame. But the Nikon Scan software is clunky in a 1990s manner and needs a computer running WIN XP or 7. I will test Silverfast 9 on my Mac for future use, or may try a Windows emulator and load the NikonScan on my Mac. The native Mac versions of NikonScan would not run on the Intel chips. 

My 1949 Leica IIIC:  The extra washer on the bottom post may have solved the problem of the buckling or curved film. It is nice to keep this old family friend in operation. The 5cm Summitar is an impressive lens, especially considering that it was designed in the 1930s.

Have you tried VueScan with the Nikon scanner? Nice results from this film.

I don't see anything to complain about in the results from that old B&W C-41 film. Home processing of any C-41 film whether b&w or color is simple because there is no adjustment needed for variables like film speed other than a bit of adjustment in exposure to compensate for age. Time and temp are the same for any C-41 film and the cost for processing at home adds only about a buck a roll.
I still like my old version of Silverfast on my ancient XP rather than VueScan in the IMAC because the Silverfast preview seems to give a much quicker and better view of adjustments before making the final scan.

Hi Y'awl,
I tried Viewscan some years ago when I was setting up my medium format Minolta film scanner. The interface was confusing, but, I'll admit, did not give it enough time to become familiar. I prefer Silverfast, but am familiar with it because I have used various versions for 20 years. There is a Silverfast 9 to run the Nikon Coolscan 5000 from my Mac. The NikonScan 4.03 may operate the infrared dust/scratch function better. I will test more in the future. I will use more of the T400CN because I just bought two more rolls.
