From a prolab point of view it provided additional products using existing printers and processes.īW films for Process C-41 was not a big volume or success for any of the film manufacturers. This allowed prolabs to make monochrome prints on RA-4 paper. PORTRA 400 BW had the same color characteristics as otehr PORTRA Films so it could be analyzed and printed with other PORTRA Films. This was a major driver in making PORTRA Films a huge success for Kodak. This allowed labs to handle all PORTRA Films the same no need to segregate films. One of the advantages of PORTRA Films was that all the PORTRA Films could be printed using the same analysis and printing channels. It allowed the labs to provide and additional product using existing printers and processes. It allowed making b&w prints from color negatives using existing printers and RA-4 paper process. This was used in the school picture and commercial lab business. Rather than producing CMY dye imageįrom respective RGB records the print dyes were " mixed" to produce a near neutral print image. This was an RC paper for RA-4 paper process. It could also be printed on b&w paper but required long exposure times.Īnother attempt at monochrome prints was EKTAMAX Paper. This required a special printing channel on automatic color printers. Later various b&w films for C-41 process were sold that could be printed to color papers producing almost monochrome prints. It competed successfully with Agfa VARIO PAN and ILFORD XP1 and XP2. This was intended to be printed on BW Paper using enlargers etc. Later, after higher priority projects were completed, T 400 CN was commercialized using more conventional dye-only technology. A major factor in never pursuing this was it was not reasonable to place future constraints on Process C-41 in order to make a performance improvement in a very small volume product. This technology was never commercialized. Even in retrospect this was the best decision. We had limited resources so we chose to pursue T-MAX Films. ![]() This was achieved by using a bleach restrainer in the emulsion. ![]() The film provided an image that was a hybrid dye-and-silver image. We had a 400 speed b&w Process C-41 film with grain that was much better than TRI-X or the other B&W C-41 films on the market. You''d be amazed at the enhanced tonal change you''ll receive.In 1981-82, prior to T-Max Film, we (Kodak) did some experimentation with chromogenic B&W films. If you're just starting out, you may want to consider film developing starter kits. For example, a C-41 developing kit contains bleach, color developer, and stabilizer. It seems to me anyone who has tried this film to unsatisfactory results, simply isn''t utilitze a professional lab with a qualified printer at the helm, or needs to start rating this film properly at E.I. C-41, E-6, and RA-4 kits are available and include all the chemicals you'll need for that specific developing process. For architecture and landscape, and portraits, T400CN is a winner. Tri-X and Fuji Neopan 400 still tops for me. Since I prefer the added textual quality grain provides in my dad to day, and even some portrait shootings, I shoot non-chromogenics. When I want no grain, I shoot T400CN, period. You always strike a compromise somewhere with these films. It has a beautiful smooth tonal range I love, but cannot match T400CN for its overall grainless look. Since this is not the ONLY B&W film I use, I recently began shooting Fuji 100 Acros based on recent reviews. If you''re an amateur, I strongly suggest you consider this film as mini-insurance policy in tricky lighting situations. Try that with any non-chromogenic and kiss half your prints goodbye. 200 to 800 on the same roll with fantastic results. The best attribute to this film is its latitude. I know printers who disagreement with me, but all I have are my own prints for comparison. I personally prefer this chromogenic over Ilford XP2 Super, which I find doesn''t enlarge as cleanly to 8x10 and 11x14 as T400 does. Yet, I have two 4圆 prints on my wall printed from Rite-Aid on T400CN. ![]() If a pro has difficulty, you can bet a computerized mini-lab machine will be of no help. At 400 rating, I have heard complaints about how difficult (time consuming) it can be to find the right contrast range. And yes, I only use professional printers here in L.A. I almost always rate this emulsion at 200 - sometimes 100, depending on contrast variation of the scene. ![]() I have photos to 11x14 that look medium format to even the most discerning eye. I''ve shot almost every B&W emulsion over the years, and never found any to date that can rival T400CN for its latitude and lack of grain (being a dye based film). ![]()
