NB: Phantom Markets

The depth of products for photographers, particularly darkoom equipment, declined rapidly in the 90s, the time that most of the current beginners opened their eyes. Providing information about how things were done is more useful if provided with enough background to provide grounding. Rather than tieing their laces together, shut up.

Everyone asks for “it” — upon its production, most have a reason for no longer needing it…

So, the boxes of knowledge weren’t needed.

Amateurs make more requests than most makers can satisfy. As a market declines requests are as likely to be fantasy, role playing more likely. These assumed buyers flee, actually, they never existed. They were suspects, not prospects. No way to close that deal. Most online communities are intended as gossip centers. Sales talk. Buy and sell is the way of exchange. Few members have depth of experience. Most members, most people, even those declaring themself curious, have a narrow decade of knowledge… frequently, craft-skill is more limited than academic transferable awareness; even this is lost after a decade of disuse.

What we have is a gathering of curious, unskilled people passing on hearsay as teaching.

Peak commercial darkroom equipment sales was in 1979. The commercial, custom printers knew this; honest sales reps were quite clear about upcoming deals to be made, going so far as advising other avenues of purchase.

How Groups Grow: dilution or distribution of effort. Online communities cluster in skill pools much as occurred in regional settings . These skill pools are never culture-free clusters.


The AGO Film Processor and B’s Processor are both designed for home film development, but they differ in functionality and design. The AGO offers automated agitation and is compatible with Paterson tanks, while the B’s Processor rotates the entire tank and is known for its compact size and ease of use. Here’s a comprehensive comparison of the Ago Film Processor, B’s, Jobo Silverbase, and Pira Darkroom Helper based on their functionalities and notable features.

  • User Experience: Battery-operated, allowing flexible usage in small spaces.
  • Pros:
    • Automatically compensates for temperature variations.
    • Includes pre-loaded programs for diverse chemical kits.
    • Efficient for both black-and-white and color processing.

B’s Film Processor

  • Technology: A more traditional processing unit, requiring manual timing adjustments.
  • User Experience: Generally more affordable but less feature-rich.
  • Pros:
    • Cost-effective option for users who do not require advanced features.Around $145
    • Simpler operation for those familiar with manual processing.

Jobo Silverbase

  • Technology: Rotary processor that employs magnetic rotating for even chemical distribution without a water jacket.
  • User Experience: Known for its compact design and efficiency, particularly for black-and-white films.
  • Pros:
    • Compact and user-friendly.
    • Excellent reproducibility of results.
    • Allows use of less developer with one-shot solutions.

  • Estimated cost $250

Basing a product on Jobo or Patterson seems safe. Jobo having vocal suppoters, Patterson being owned by a larger manufacturer with multiple product lines.

seeing magenta

ask around the net for dye-transfer information. seek insights, perhaps advice, what you are provided by 2025 search-AI models is counter to insight — confusion is increasing. Dilution over diffusion flourishes. Clicks are the clique formers.

One simple example. Seeking specifics about Kodak’s magenta dye used in Dye Transfer printing.

NB: search used this tree [:: Photrio -> koraks ] getting to an answer about magenta dyes used in Kodak dye-transfer, imbibition printing. Photrio is large site with over a thousand posts related to dye transfer; koraks site is listed as sigline in posts by a moderator taking part in dye-transfer related threads over the past several years. I doubt that K~ has ever made a dye transfer, certainly hasn’t synthesized the dyes. Another example of dilution of knowledge.

The inference engine of AI cannot distinguish quality, meaning accuracy, applicability, from quantity, meaning the number of referral links made over time. [the specific information provided in this conversation is based on general knowledge and does not directly cite specific pages or sections from these references.] Different models often respond that the information on [dye-transfer] is collected from practitioners internet archives.

Kodak CIS-154 Magenta Dye in Imbibition Printing
example response: I want to be transparent that my previous responses were speculative and not directly based on the Kodak publication you mentioned. Providing more details will help me offer a precise and accurate interpretation of the source material.
[I used 5 different engines... none could provide useable, correct answers.. each required, in essence, that I give them direct references, which they then could summarize. ]

Provided that I correct enough, staying with the multiple AI engines, we get somewhere. However, I had to provide a page, a CAS number, then prompt the answer machine with guidance on selection criteria for synthesis. In other words, I had to know much more than any of the AI engines were able to source. I was provided patent references, incorrect, so taking additional time for me to read, and return to prompt for correction. The initial failure though, the one leading through the darkroom help forums sounded, to the untrained, inexperienced, like a correct answer. An answer which would be repeated by the novice.

Since the process is being used by mere handfuls who do gather and exchange information and support these aren’t significant practical matters. The failures keep the stalled busy, out of the way. The lesson is that small errors can be amplified sufficiently to distort information into a contorted arcade reflection of what was.
