However, some literature replaces copper toning by a form of uranium toning which produced a similar image colour, and eventually by mordant dye toning. When tinting was combined with other coloring techniques, for example, with toning or stencil coloring, technical difficulties often occurred. Power Metal Lyrical themes: If the Excel list is well designed there need be no searching for scenes within any roll, as the next scene required will always be at the head of one of the rolls. Moreover, the wear and tear of the film should not be impaired in any way after dyeing, and even after incubating for 48 hours at degrees F. If the film is post-tinted the clear base shows through the scratch. Paul Read and Mark-Paul Meyer: Once seen and identified, many of these effects are recognizable again.

However, stains and unevenness caused by storage, fading, and projector lights are all recorded; many dyes are highly saturated and some are outside range of the recording system. The earliest attempts were usually poor and of too high a contrast but today a closer visual match to the archive original can be achieved. Read, Paul; Meyer, Mark-Paul Today, this would seem incredible and although literature of the time occasionally describes this, it is sometimes difficult for a modern film technician to accept. Tinting, as carried out by film laboratories, is a simple process. As far as is known no one has used uranyl nitrate recently for a modern restoration, since all the mordant dye procedures can be carried out using potassium ferricyanide which yields silver ferricyanide as the mordant image, and a similar result. This coloured stripe would be very easy to identify, but we have never seen an example nor did the Nederlands Filmmuseum survey of their own collection reveal any.

All of which makes it certain that the perfect educational picture must be in perfectly natural color. Many copies of this film exist. Inspired guesswork experience from a knowledge of the most likely technique used at the time.

It is also a texture of the city of Amalfi. Film which has been fixed in a stresming containing ordinary, or chrome alum, dyes more quickly than that treated with plain hypo and hardened with formalin. The edition of the Eastman Kodak tinting and toning manual cautioned that toning and mordanting were not advised for films that were to be preserved for a long time, because a fiilm alteration of the emulsion was considered inevitable and the results were impossible to forecast. It seems likely that early nitrate films suffered the same problems modern film stocks and that this was why other toning methods replaced it.

In simple words, they work to make the film more interesting and attractive.


Film History The earliest photographic processes existed before the discovery by mistake of the first artificial dye Mauveine by Perkin in England in They function as streamibg attractions and incitements to fantasy, rather than harmonious and subtle appeals to an established aesthetic order, or carefully observed images of nature.

Taken off after colouring the print acts as a visual and a densitometric control for each colouring procedure.

With tinting, a section of a film was dyed a specific color usually by running it through a bath of aniline dye so that the emulsion would absorb the colorant. When R, G and B densities are plotted on a trilinear graph paper not a technique normally used in photographic control and this displays colour in a manner that is very similar to the way the human eye perceives. In effect, short single scenes were made up into small rolls which were then printed in one printer pass for each roll onto lengths of print stock.

A two-reel vertical winder, with or without a synchronizer, is useful. This loose term presumably originated with Eastman Kodak, but other authors use the same terms often referring to other dyes. This is all perfectly practical but as far as the authors are aware has never been done to a long feature film since the processes ceased to be used commercially.

The co-founder of Vitagraph, J. Toning consists in either wholly or partially replacing the silver image of the positive film by some colored compound, the clear portions or highlights of the image, consisting of plain gelatine, remaining unaffected and colorless. A similar case is Amalfim. Peak wavelength absorption is useful and reasonably easy to measure.

To see a visual demonstration of this, look at a black-and-white photograph through a coloured gelatine filter; what you will see is exactly the same image as a cinema film frame where the clear film base has been dyed that colour. Similarly, Gaumont intertitles were often tinted blue-green. When delicate tints are employed, the effect is both to remove the contrasty black and white effect, and to add a touch of warmth to the black deposit of silver, even in cases where the highlights are italix stained to be noticeable.

The materials employed at the beginning of the century the nitrate bases and dyes have a unique appearance that cannot be reproduced. The overall dramatic effect is probably very close to that of the original. And as inevitable as the perfect educational itself is the perfect color process—it is yet of tomorrow.

Two details characterize a tinted nitrate print: Hand coloured and stencilled prints have generally been preserved on colour internegative, but much of the tinted and toned material has not been preserved in colour. In other words, though the indexical bond between a color and its object is severed when reproduced in black and white, its harmonic sensation can be re-created—translated with nice effect—through these applied color processes.


Soho Images, London, has an extensive library of tints and tones representing some forty different tint and tone dyes from silent-era England and a few other European countriesmade under different process conditions of dilution, acid content, and time, all using a single standard print image for comparison.

A suitable test as to whether a dye has any propensity to produce brittleness is to incubate a sample of film, half of which has been dyed, for about 48 hours at degrees F. Stencilling and hand colouring was the process of locally applying tint dyes to the silver image. Comparisons of the two methods suggest that the results are very similar but the use of a black and white negative material results in finer grain on the final print, and the Desmetcolor is considerably lower in cost.

This method was used by Soho Images to demonstrate the closeness of match between original dye and reproduction to the Nederlands Filmmuseum.

We are of the opinion that the effect was never intended, may have been retained from sense of serendipity, and some may well date from the original print production, although we cannot be sure. Please contact Barbara Flueckiger to ask for the permission to get access to the authors’ interface.

Poor correspondence with the aim agreed with the archive allows corrections to be made it is a curious feature of tinting and some toning techniques that if the effect is too light it can be retinted, if too dark it can be washed out!

When a film coloured with this system is projected the image appears dark on a coloured background. Strong colours can be obtained and they are quite repeatable.

Charlie Keil and Shelley Stamp Berkeley: However, an American laboratory textbook of and a French manual of both imply that laboratories at that time still tinted much of their own prints as a routine.

If the image is printed somewhat dark an effect not unlike tinting can be achieved but the image loses much of its aesthetic value.
