The result, known as the Sabattier effect, resembles solarization.
However, researchers have shown that Mackie lines are not part of the Sabattier effect itself.
During this time he began creating a series of highly distinctive nudes that used the Sabattier effect to meld form and surface together.
Armand Sabatier, discoverer of the Sabattier effect (see notes below).
Sabattier effect, a photographic darkroom process (also known as pseudo-solarisation) that results in a partial image reversal.
This led to the use of the Sabattier effect for obtaining first and second order equidensities for photogrametry and equidensitometry.
The term is synonymous with the Sabattier effect when referring to negatives, but is technically incorrect when used to refer to prints.
The author's name was erroneously written with a double t. The effect which was arguably named after him is since then known as the Sabattier effect.
Spencer defines the Sabattier effect as: "Partial image reversal produced by brief exposure to white light of a partly developed silver halide image".
As said above, it is very difficult to manage all parameters for yielding consistent results when using the Sabattier effect and therefore other means of obtaining equidensities have been pursued.
The pseudo-solarisation effect or Sabattier effect was described in print by H. de la Blanchere in 1859 in L'Art du Photographe.
In scientific photography it was soon observed that when using photographic films with very high contrast (also known as lith films), the image produced by the Sabattier effect exhibited a multitude of lines of various width, representing a specific amount of exposure within a certain range.
Dazeley is one of the few modern photographers working with Platinum prints and is currently working on several projects including X-ray, flowers, pregnant women, anamorphic nude and solarisation (Sabattier effect) photography, out of his own studio complex in Chelsea, London.
Sabatier published near the end of 1860 a process of obtaining direct positives, but according to the description, this process did not seem to have any connection with the Sabattier effect as no mentioning was made of any exposure of the Kollodium plates after development had started.
However, solarisation is very difficult to manage to yield consistent results.
They then applied the defined solarisation curve to real time video images.
It is therefore always possible to determine whether the negative or print has been used to produce the solarisation effect.
In colour photography, different coloured lights can be used to effect solarisation, but the results become even less predictable.
A goal was to extend the range of solarisation effects possible to a computer specified curve.
Solarisation became the discovery of the age, catapulting photography from craft to fine art.
John William Draper was the first to call the overexposure effect solarisation.
Together with Man Ray, she rediscovered the photographic technique of solarisation.
This process can be coupled with solarisation so that the end product resembles a negative and is suitable for printing in the normal way.
The solarisation effect was already known to Daguerre and is one of the earliest known effects in photography.
Additionally, he experimented with solarisation and explored the possibilities of the Sabatier effect.
Her complex surrealistic images were often achieved by means of collage, photograms, or solarisation.
Solarisation with control - great!
Secondly, the boulders are suffering from solarisation.
This partnership reached its peak in 1930 with their accidental discovery of solarisation, a technique which lent a photograph a silvery aura.
Initially, the term solarisation was used to describe the effect observed in cases of extreme overexposure of the negative in the camera.
Solarisation may refer to:
Regular access to a lab has provided Dawson with facilities to experiment, and he's been working with solarisation, changing the colour of the base of the film.
A large white horizontal cylinder used to hold the gas supply for the lighthouse light which was converted to electricity during the refurbishment and solarisation in around 2004.
The film was also delayed in its release (owing partly to the use of solarisation, a then-new technique both laborious and expensive), and badly under-promoted.
To achieve this effect, a black and white film negative was first processed with solarisation (a process which partially reverses the negative making some areas of the image appear positive).
Fused quartz is prone to phosphorescence and "solarisation" (purplish discoloration) under intense UV illumination, as is often seen in flashtubes.
The "solarisation" of several local gods (Hnum-Re, Min-Re, Amon-Re) reaches its peak in the period of the fifth dynasty.
Control of existing Phytophthora infestations includes injecting or spraying plants with phosphite (a fungicide), using well-composted mulch, and using pre-planting techniques such as solarisation or biofumigation.
Light fogging on a print usually only occurs because of poor control of lighting in the darkroom and is seen as an overall dark veil across the print or, occasionally, as unintended solarisation.
