This item will ship to United States , but the seller has not specified shipping options. It was a very specialized field of transfer-and I was intrigued. Los Angeles, California, United States. The Keller-Dorian system of color cinematography was a three-color additive system based on the invention of Rudolph Berthon. Viewing it under sufficient magnification should confirm this, or identify it if the edge marking is not present. Diagram of a colour screen, showing how the filters were positioned in front of the camera lens. The Kodacolor filter split white light into red, green, and blue wavelengths. Skip to main content.

Heather Gordon June 9, at A lenticular lens array Roberts, Due to the difficulty with the subjectivity of many elements regarding the condition and contents of films, they are all sold as is. The physical movement of the film through the gate frame-advance requires additional time. Dubbed Chronochrome and produced by Gaumont, this system resultantly eliminated the issue of motion blur, but introduced new problems of parallax discord which again created distortion.

This page compiles Kodacolor resources I come upon and has been a long time coming. I like the camera projection process as it simulates a pretty accurate viewing experience. This entry was posted in Holdings and tagged AberthaufilmslenticularSpencer family.

Perhaps the most infamous example of this chemical muck-up came in the early s, with the debut of Eastman stock — or, as it is better known, Color Reversal Intermediate, or CRI. Nevertheless, despite its infinitesimal length, this split-second interval remained enough to cause a fringing effect during fast motion and close-ups, a result of each subsequent, different-colored record being slightly out of register with the previous and proceeding frames.

It ONLY fit when the aperture was fully open at f1. Delivery times may vary, especially during peak periods.

It could not yield multiple copies easily, special film was necessary to shoot with, and the additive image was colorful and clear, but inherently darker than subtractive processes. In fact, the dyes which form the green and blue layers on a positive element cyan and magenta on a negative fade gradually over an extended period of time, with the result that the overall colour balance is disrupted and the image takes on a pink hue.

Thank you to Paul Ivester for the below information and images.

We have 69 amateur films shot by various members of the Spencer Family from the s to the s. Film Technologies strikes a color negative using an optical printer. Unfortunately, Kodacolor was plagued with inconveniences. But whatever these changes were, they made the resultant exposed and processed film much more prone to fade.


The earliest known subtractive color processes involved the use of duplitized stock, which was stock specially constructed to contain emulsion on both sides of a single base. Polyester colour negative of [Gardens at Aberthau] on our light table. Given the nature of its production, it presents few potential problems beyond standard black-and-white positive print degradation, with the exception of recognizing and correctly restoring tone fading on both sides of the duplitized emulsion.

Tests completed with the process showed improved results in saturation and color channel registration over traditional photochemical methods.

Ironically, it was the nascent small-gauge home and amateur formats that actually offered much better potential for experimentation in additive color, largely due to the fact that duplication of originals for mass distribution was no longer kdoacolor.

A History of Color Moving Images: Problems Posed in Preservation

But it is the process itself that presents the greatest challenge toward being preserved and restored. After processing[,] the silver halides were washed away in the exposed areas, allowing light from the projector to pass through the coloured reseau and illuminate the screen.

In the end, it is fascinating to remark that for all lentiuclar technological advances, the reproduction of color continues to be achieved via a breakdown of the process of perception into its constituent elements: Skip to content This post was written by Criss Kovac.

Under a loupe, the film appeared to have a large, pixel-like grain akin to standard definition video. The later Super Sensitive Kodacolor could be used “outdoors in any good photographic light, and even indoors under favourable conditions.

In motion picturesKodak’s Kodacolor brand was associated with an early lenticular additive color color motion picture processfirst introduced in for 16mm film.

Get the item you ordered or get your money back. By a correct choice of the radius of curvature of the lenticules, each lenticule can be made to form a sharp image of the lens aperture on the emulsion. Have one to sell? There are 1 items available. Please help improve it or discuss these issues on the talk page. Unfortunately, in terms of the restoration and preservation of color moving fim, there seems to be no one set answer.


The camera requires a special lens which splits the light into three separate bands of kofacolor, green, and blue, which are then captured in the lenticules.

Discovering Kodacolor at CFA – Chicago Film Archives

He would make a special effort to complement anyone who would wear a bold color. Further, because the process involved the layering of separate dyes rather than development, it presented a very important ancillary benefit: We would also like to thank Tommy Aschenbach of Video Film Solutions for developing the software and putting in all of the time and effort to preserve the content of this film.

The lenticules are barely visible. California residents pay sales tax. Several years later I lucked upon a working Kodascope Model B 16mm projector that included a Kodacolor filter and thanks to a new a scanner and digital camera, this and other stuff are on the internet for the first time.

Kodacolor is black and white to the eye, but is color when projected through the proper filter. Also included in the cardboard box are an ND and color filters, metal cases for all three filters, and a metal sleeve. Early two-color subtractive lenficular such as Lenticula, Prizma, [31] Brewster Color and first-generation Kodachrome which used a completely different process from its later successor and was introduced in[32] were shot using a bipack process, which involved two strips of film acting as color separations being shot simultaneously, emulsion-to-emulsion, the upper orthochromatic layer collecting blue-green registers and the panchromatic bottom layer recording red-orange hues after the removal of the blue-green wavelengths via an intermediate filter.

To almost anyone born in the last half century, the existence of color motion pictures probably seems like a given. Also, the lenticles are more pronounced.
