Finding Film Data

We are in times of out dated film — film from unknown storage — film without datasheets. So, to the netfora with a question; like the camera counter of last century, except, these people are retired accountants, roofers, support staffers. Few of them worked as photographers; fewer still kept their old notebooks, those collections of datasheets. Firms like Kodak produced massive stacks of data in the form of how-to guides, along with instructional books — not even mentioning the many datasheets inserted into countless boxes of film/paper.

So, to the Loud Forums with a question:

Kodak Copy Film

The answer is quick, intended to assist, but does it? How much help? Go somewhere else; look in a booklet you don’t have. Oh, and the obscure developers are wrong, but not really, they’re just flailing answers. The answer is online; in two archive books. And now here:

Kodak 4125 Copy Fillm

The exotic developer is HC-110 (Dil E). This film was used indoors, I used it at tungsten settings, EI:12. It was also used as a lab film, in darkroom using enlarger light. Read the guidance about exposure and control of highlights. That is why it could be used in a masking system, and in duplicate negative making, although, I used dupe negative film for that: made it a one-step process.

So, I could pass this info on to the Loud Forumists; why don’t I? I don’t have a login. They are boring people trapped and trapping others, like some vast herd stuck in bogs.

RA-4, Big Lab Printing

They are called “chromogenic,” or “type C,” because that is what Kodak called the 1950 printing process. They are called “Lightjets” because Cymbolic Sciences got there first. They are called “digital C’s” as a product neutral designation; a way to distinguish them from inkjet prints. The labs using these machines are major users of silver based photosensitive paper. They keep the wide papers being made. Narrow paper is used by the scrap-book, duplication systems at drugstores.

The Lab Machines:

Printers include the Cymbolic Sciences Lightjet, Durst Lambda, and ZBE Chromira.

The Lightjet was introduced in 1996. It is laser based, as is the Durst Lambda, while the Chromira is LED based output. Lightjets were the most expensive at introduction, and now are the least likely to be used because of their high maintenance costs. They do provide very wide output along with being reasonably sharp images. ZBE claims they provide the highest resolution of these three systems.[https://www.zbe.com/5×50-printers/]

Durst’s main site no longer lists their Lamda. Print systems don’t wait for the past. https://durstus.com

And Cymboli Sciences is a division of Oce. {https://en.wikipedia.org/wiki/LightJet}

This post is just another plug into the leaky rumor which is the Film Net of Larger Format and Photrio. Most mistakes seem to be outright lies; lies designed to explain, to defend a long held belief. Unfortunately, once a failure, always a failure. Even in fantasy, a failure. Wiling away the dreary life of filling order sheets for the door store —
