The Sabattier effect, also known as pseudo-solarization (or pseudo-solarisation), is a phenomenon in pictures during which the symbol recorded on a negative or on a photographic print is wholly or partially reversed in tone. Dark spaces appear light or gentle spaces appear darkish. Solarization and pseudo-solarization are relatively distinct results. Over time, the "pseudo" has been dropped in lots of photographic darkroom circles and discussions,[1] however the effect that is supposed is the Sabattier effect and now not the solarization by means of extreme overexposure (see under).

Background

Initially, the term "solarization" used to be used to describe the effect observed in cases of utmost overexposure of the photographic film or plate in the digital camera.

The effect generated in the darkish room used to be then known as pseudo-solarization. Spencer[2] defines the Sabattier effect as: "Partial image reversal produced by brief exposure to white light of a partly developed silver halide image". Many alternative ways of chemical[3] and actinic radiation "exposure" can be utilised for the partial symbol reversal.[4] The use of chemical substances for symbol reversal is also known as 'chemical fogging'.[5]The SPSE Handbook of Photographic Science and Engineering describes the effect as follows: If a movie that has been uncovered, evolved, and washed however now not fastened is given a 2nd uniform exposure and advanced once more, a picture with strong border results is obtained, which combines the original image with a reversed (certain) image.[6] Another usable definition is by Wijnekus & Wijnekus: If an exposed, incompletely developed, and washed, however not fixed movie is given a 2nd uniform exposure and developed again, a reversal of the original image is also got. The reversal is also partial or entire, depending on the relative magnitude of the first and 2nd exposures.[7]

History

The Pseudo-solarization effect used to be described in print by H. de l. a. Blanchère in 1859 in L'Art du Photographe. It was once described again in 1860 by way of L.M. Rutherford and C.A. Seely,[8] separately, in successive issues of The American Journal of Photography, and in the identical year through Count Schouwaloff in the French e-newsletter Cosmos. French scientist Armand Sabatier revealed 26 October 1860 a technique of acquiring direct positives (referencing Count Schouwaloff and Poitevin),[9] but in keeping with the description, this process did not seem to have any reference to the Sabattier effect as no citing was once product of any exposure of the collodion plates after development had started.[10] The name of the writer was erroneously spelled with double "t" and thus the effect is therefore known as the Sabattier effect in maximum literature.[11][12] Sabatier described appropriately the phenomenon in 1862.[13][14] However, Sabatier may just no longer to find an reason for the phenomenon.[12]

The effect was generally caused via accidentally exposing an uncovered plate or movie to light all through creating. The artist Man Ray perfected the technique which used to be accidentally came upon in the darkroom on account of fellow artist Lee Miller by chance exposing his movie in the darkroom. It is glaring from publications in the 19th century that this phenomenon was once found out again and again by way of many photographers because it has a tendency to happen whenever a mild is switched on inadvertently in the darkroom while a movie or print is being advanced.

Explanation

Whereas many photographic results had been researched and explained in this type of approach that most researchers agree upon them, the Sabattier effect does no longer belong to that crew. In normal the following info are authorised by means of the community of photographic researchers:[12]

The assumption that the Sabattier effect can also be attributed to the Solarization effect may also be overruled. The opinion that the Sabattier effect is an instantaneous "print-through" effect of the silver produced through the first development on the beneath positioned layers cannot suffice to provide an explanation for the effect. It has been shown that exposing a photographic layer thru the base also displays the Sabattier effect. Moreover, chemical fogging is also proof that copier effect is most effective marginal in generating the Sabattier effect. Oxidation merchandise produced all over the first building at the developed grains can't reason a desensibilisation of the unexposed grains. It is tricky to check that the silver produced all through the first construction has a desensibilitating affect on the first evolved grains. However this level should be additional researched. Although with business photographic materials the speed of building of the latent symbol of the 2d exposure is more than that of the first development, it can't be the figuring out factor for the Sabattier effect. Several researchers assume that the construction of a latent interior symbol as results of the first exposure thus affecting negatively the floor "specks" (also known as latent image facilities) caused by way of the 2d exposure can in part provide an explanation for the Sabattier effect. One of these researchers, Dr. K.W. Junge, published an cause of the Sabattier effect as follows:The photographic subject material suitable for pseudo-solarizing must have an overly low tendency to provide surface specks. This is usually achieved by means of prohibiting the chemical adulthood during production. During the first exposure therefore virtually simplest inner grain specks are produced. The first construction will spoil the tendency to produce internal grain specks so that after the 2d exposure additionally grain surface specks are produced. These are only produced on grains which have nonetheless no inner grain specks. The explanation why for this is that all through the 2d exposure electrons emerge which can be a lot faster caught via the stable and big internal grain specks than they can serve to build new and smaller surface grain specks. The 2nd construction in a surface developer will now attack the ones grains which remained unchanged by way of the first publicity in order that an image reversal will occur. The indisputable fact that as a substitute of a 2nd publicity electron donating techniques (e.g. chemical fogging) will also be added to the second developer helps this principle.[15]

Careful number of the amount of light used and the precise second in construction to supply the further exposure offers rise to different outcomes. However, pseudo-solarization is very tough to control to yield consistent effects.

As a guide, an publicity of one 2d to a 25 watt incandescent lamp at two metres distance at round the finish of the first minute of a 2-minute construction can produce acceptable effects. If the exposure is made with the growing print nonetheless in the tray of developer, it is essential to forestall agitation a minimum of 10 seconds previous to publicity to allow any bubbles on the surface to disperse and to be sure that the print is lying flat. Pseudo-solarizing color prints is tougher as a result of the extra cautious control of temperature and timing that is required and since maximum novice processing is undertaken in a processing drum reasonably than a dish. As lightsource additionally an enlarger without unfavourable in the carrier can be utilized. In color pictures, other coloured lighting can be utilized to have an effect on pseudo-solarization, however the effects change into even much less predictable.

Using the Sabattier effect it will have to be obtrusive that it is very difficult to control all parameters for yielding consistent and predictable results and due to this fact other approach have been pursued corresponding to Agfacontour and special pseudo-solarizing developers[16][17]

In medical images it was seen that when the usage of photographic films with very high contrast (often referred to as lith movies), the image produced through the Sabattier effect exhibited a large number of traces of various width, representing a specific amount of exposure within a definite vary. This ended in the use of the Sabattier effect in the fields of Photogrammetry and Equidensitometry.

Agfacontour Professional Film

In 1970, Agfa advertised Agfacontour Professional Film, which simplified the strategy of acquiring consistent effects for pictures that regarded very similar to pseudo-solarized images and therefore it was once widely utilized in equidensitometry and art.[18][19] This particular purpose film addressed the uncertainty of pseudo-solarisation results.

As of 2002, Agfacontour Film was once not being produced.[20]

In digital media

Early video synthesiser technologists concerned themselves with attaining arbitrary curves now not restricted by means of movie chemistry. A purpose was to increase the vary of pseudo-solarization results possible to a computer specified curve. They then applied the outlined solarization curve to actual time video pictures. A video lookup desk was once frequently used to put in force this. Using this enhanced solarization generation, still footage may be handed via a gray scale or colour lookup desk with the advantage that the effect may well be previewed and gradually progressed, as a substitute of a process in response to darkroom exposure calculations implemented on a one time foundation to a unstable gentle sensitive movie or print, as described above. This used to be an especial merit for creating color solarizations with 3 number one colours.

Graphs describing pseudo-solarization curves generally place input range of tones on the x axis, with black at Zero and white to the appropriate, and the output vary of tones on the y axis with black at Zero and white up. A curve then defines the input to output mapping. Manipulating custom curves in photo-editing systems reminiscent of Photoshop supply gear to imitate the Sabattier effect in virtual symbol processing.[1]
