Is this a sheet film? Cancel Forgot your password?
In this case, it was possible to correct the balance of the print by adding a filter of the same colour cast as the overall shadow area cast or, better still, decreasing the filtration of the opposite colour, magenta. Hi everyone, please could anyone help how to use this film “Kodak commercial internegative film “? With experience, the shadow to highlight balance of badly exposed transparencies with colour casts could be modified by filtration and exposure changes to give a much improved copy. It replaced Kodak Ektacolor Print Film. The transparencies were intended for projection but, when projected onto a white wall, they gave an odd, diffuse, unsharp image compared to High Speed Ektachrome film transparencies. The purpose of the Additive was to compensate for the effect of the Print Film or Slide Film on the chemical balance of the developer. The internegative exposure giving the best print could be used for making internegatives from the vast majority of transparencies. This was to provide additional interimage effects to enhance the colour reproduction characteristics of what was a quite complex emulsion of the time.
You can just develop it as usual in C or send it off to the lab. Kodak Vericolor Internegative film, see abovewas recommended for copying maps and flat artwork. That said, I remember seeing negs stored in one New York lab in an old closet with a leaky ceiling Some features of WorldCat will not be available.
The base thickness was about equal to 35mm colour negative film, much thinner than Ektacolor Print Film. I’ve shot it at as well though with dreamy results. Filtrations for Ektacolor Print Film were similar to those on Ektacolor papers, but most negatives required a higher magenta filtration compared to the colour papers.

Although the transparencies could be printed onto the film directly, Agfa recommended for best results a black and white contrast reducing mask should be made from the transparency first to be used in register with the transparency when printing onto the ZN film. The development times for Ektacolor Internegative films were 5 minutes for the sheet film or 6 minutes for the 35mm film, and other sizes such as 46mm and 70mm.
The lab technicians would run many test strips to set up their exposures, and that’s probably what you should do to figure out the correct ISO for shooting this stuff in the field.
This is set out below. The film was generally about half the speed of the printing paper. Any number of duplicates could be obtained and the results on Print Film were far better than trying to duplicate an original Ektachrome or Kodachrome transparency onto Ektachrome Type B sheet film.

This type of label, in varying forms, was introduced for colour sheet films in The contrast was not altered. Having made 10inch x 8 inch transparencies on this film from Ektacolor sheet film negatives on a Intefnegative Vere enlarger fitted with an Agfacolor head, Michael Talbert can say that the filtrations were similar to Ektacolor Print Film.
You already recently rated this item. Also, see his research on Kodacolor and Ektacolor Camera Film. Russ says “Note the unusual emulsion arrangement.
Contrast corrections were made exactly as on Ektacolor Internegative film see above. It then became Print Film. This box dates from It replaced Kodak Ektacolor Print Film.

Is this a sheet film? The materials described here were used in photographic laboratories for the specialist purposes identified in commercjal Note below. This page last modified: Likely you should shoot the first roll and do some bracketing.
Ektacolor Print and Slide films were processed in C chemicals, but the developing times were different to the camera sheet, roll, and iternegative films. The curve plotting method as described for Ektacolor Internegative Film. A densitometer had to be used, but readings were taken from Kodak Photographic Step tablets, Grey Scales, printed onto a strip of filmand the filtration changes could be read from a table in the data sheet showing plus or minus values to alter fklm Yellow, Magenta and Cyan filtration values.
Please select Ok if you would like to proceed with this request anyway. Four methods were given for finding the correct filtration and exposure. One of the printers was a German lady who ventured to say she had commrcial, or at least known, something about the film. The lights they use are very bright, hence the low sensitivity and latitude of the film. Add Replenisher plus Additive to the developer after processing each batch of Print Film.
Photography — Films — Catalogs. The overall contrast could be changed by varying the exposure in a similar manner to the Vericolor films.
