Middle of something

Posted on Posted in as written, minimum daily requirement, the fora

many small notes, again. Starts and wanderings. Have been in the darkroom most of the time over that past ten days. That isn’t what I will post about… some of that is on instagram, vimeo, in forms that make meaning only to my interiors

This is another collection of things I wish I could have ignored. A lesson to myself about staying away, even in a passing way from those deadly school ground spaces of the camera land. There are some things, prompts, which could lead to better ideas — lessons even from the worst of us. More about those another time.

Success is often achieved by those who don’t know that failure is inevitable.” — Coco Chanel

COLLECTION:
[Just developed in FX 39 and scanned my cache of CHS 100 II in 120. I’ve decided that’s my film for the winter (when I shoot only B&W, going back to color during “leaf” season). So, hoping it’s available again. I love it.] Hobbyists have seasons.. as do yentas


[My wife‘s anatomy instructor in Med shool died from long term exposure to it(formalin)] — too bad she had to attend such a poorly managed nursing school[ Samuel Merritt College] To the point of work exposure to cadavers, NIH has appropriate references to statistics, additional to that was a study by Serbian researchers about the point of greatest exposure, further, Johns Hopkins has an article on anatomy study — all these are just GOO-Fu away. Summary: the storage lockers are unsafe, those technicians who are smokers and/or heavy drinkers are more likely to have lung or liver cancer. Not so much anyone else.

[And I for one don’t don’t appreciate anyone pooh-poohing safety topics they don’t have the background to fully appreciate. I would have been dead long ago if I hadn’t been “paranoid” about certain chemical categories.] so, what is his background: purchasing agent for a softwood store. he is without credential or credibility.

Partial information is better than personal strutting :

[why would you want to alter a rather hard to find, expensive, top-of-the-line ‘Apo N” 150?] PERHAPS to build their world rather than defend, or conform in yours

And here was IS a list of prices … [Demand for analogue photography is surging, with the so-called ‘Newtro culture’ gathering momentum and pushing renewed growth in sectors that predate the adoption of digital technologies, such as knitting and vinyl records. In fact, the global film camera market value is set to reach almost £311 million by 2030, growing by 5.2% each year from £223.2 million in 2023.] A DREAMCAST.

CTEIN’S value over time:

Ctein dye transfers on aftermarket… between 50 and 500, although they are lowering. Maybe wait. Notice that the Berlese has higher asking price. Ctein prints are getting to the original cost of making. Perhaps the market has more wisdom than I believed.

Making up HC-110

Posted on Posted in labnotes, overnight notes, the fora

was it a key. who knows who knows what they know.

HC-110 entered the stream as an addition to dye transfer printing. My view. It appeared in literature distributed to the avid darkroom “enthusiast.” — what we called the Dentist Darkroom. Over time, Kodak taught the duo Super-XX and HC-110 to the weekenders and small, part-time printers. The reputation grew thru repetition. This century, with a sense of failing industry, HC-110 held onto its claim of mystic value by being difficult to make, hence, it would be a catastrophe for it to disappear. The value of association plays background to this.

Dye transfer, large shops, had multiple lines. The small ones could use HC-110; however, the large, deep lines would never be taken over by HC-110, so, DK-50 remained.

Enter the gossip track…

IN A SLIP OF THE LIE, HE TOLD THE TRUTH.

Back to HC-110 original style. MSDS sheets aren’t required to list every ingredient, just hazardous ones, and with trace or trade secret ingredients exempt from being listed. I know someone who didn’t formulate a personal batch; but he had access to a major research lab, and the right background to do it. It was tricky. Certain ingredients aren’t ordinarily available.]] photrio. He probably meant to say he knows someone who DID make it. The reason he makes the claim is to bolster his standing among those of little standing.

Of course, all this work was for the Old HC, the syrup, not the current HC-110.

The patents tell more. The 1959 patent is about concentrated developers. The motive is for reduced storage space, faster mixing as well as modifying gammas of film without resorting to multiple developers. The 1964 patent provides information about dilution effects. Dilution reaches a limit, which is why Kodak listed the few dilutions they did. Patents do tell a story to those familiar with reading them.

agitation changes shape of curve. Same film, & developer(DK50 1:1) difference is agitation scheme.

I used HC-110 after using DK-50. I began making masks and seps with DK-50 — after the HC syrup disappeared, I returned to DK-50. My lab films are Ilford: Delta, PanF+, FP4+, and Ortho Plus. These films provide what is needed to make masks and separations for color and BW procedures.

Avoid the forums (my recurring theme) — use manufacturers first; then check with old texts. Use google books. Most important: try things, keep notes. Be certain to follow the information of those who have done more than repeat overheard counter-talk.

Once the syrup hit the water, its main purpose is lost. Once the syrup left the manufacturing, the major value of those researchers was lost.

for the Syrup, (kodak Honey) version. HC-110 thick is gone, only thin remains

Characterizing film+developer combination isn’t as time consuming as re-formulating a compounded chemical like HC-110. Falling back to DK-50 from HC-110 is a few hours effort, not days, certainly not the months expended trying (and failing) to compound the Aussie HC-110.
