We could define a sequential contrast, in the compositions of bi-optical,

where the sequence is composed of two stages,

In the first stage of conventional image appears. containing certain stimuli and

a second image deducted from the first, taken on by an optical device.

In deducted image, when looking through a device, effects occur caused by activation the stimuli.

 

  There already adopted  contrasts in fine art: simultaneous contrast, successive contrast

Others are deducted, such as,  Chiaroscuro , in general shadow

  About shadow quote prodigious publication.

From chapter written by me would detach some ideas how the concept of cinestatism

13. Visual binarity

 

Some of my studies have as the theme of optical possibilities to developments in fine art

I cite, among others, the introduction of the compositions of fine art, of the stimuli

 resulting from graphic tests studied in Binocular Rivalry

Test for B.R. is a unit composed of two different images: for left eye and right eye respectively.

 

Tests B. R. composed of R.Blake were used in magnetic resonance research

achieving changes in the brain photographed image.

Subcortical Discrimination of Unperceived Objects during Binocular Rivalry

 

By entering, in, bi-optical compositions, different stimuli

resulting from research in the field binocular rivalry, together with the color fusion Helmholtz

and in stereoscopy, using an optical device for observing composition

result, several effects as:

 

antispace, bispace, hiatus and hyperspace in art, dynamics of space depth, hyperrealistic effects,

 psychic cycle, psycho- physical mixture of colours, retinal "cooperation",

 space and time in bioptical art, spatial harmony, spatial disharmony, visual gradient, etc.

(as in space without gravity)

 

  In the image inverted the forms appear to occupy space partially common

 (perception of penetrable)

 

 

I quote an original composition composed by artist Aura Bălănescu, composition

that I consider in   bi-optical class, in that it shows sequential.

(second image deducted, mediated by anaglyph glasses)

 

 About Aura Bălănescu

As a graduate of Faculty of Fine Arts and Design, Sculpture Department (2003) West University, Timișoara and Doctoral Studies of the same institution (2010), Aura Bălănescu explores various extensions of sculptural work, among them being the stereoscopic representation. In her vision, this type of representation has the potential of painting, sculpture, graphics and also the environment and these premises approaching it to the character of an integral artwork.

 

Aura Băbălanescu manages the basic composition to be artistic, avoiding

overlapping colored images, visible with the naked eye, looking in anaglyphic process.

To achieve this effect she studied a selection of colors, because the color filters for anaglyph induce restrictions.

The Black Sun looking using colored glasses obtain a form in space, substantially different from the form seen with the naked eye.

 

I believe that this composition shows a strong sequential contrast

   in terms of change in the perception of form, achieving the effect of static signals, without kinetic changes, during contemplation composition (physical, lines, colors).

 

Anaglfici glasses (two filters attached to a cardboard) are on sale on the market.

 

  I photographed image through each filter of anaglyph glasses, obtaining two images, which I sit horizontally arranged to be viewed with crossed eyes.

  I got two images for stereoscopic couple as they get when looking through the glasses with filters.

  Although the quality of the filters is appropriate for the look with the naked eye,

are not adequate for proper camera that has much higher input pupil and therefore the images that I have obtained not appear clear

 

         Arranged for crossed-eye viewing

 

This method of looking is not recommended for art.

I made a kind of stereoscope for contemplation, bi-optical compositions,

that I will present below

(sereosop monocular, with the second eye look is free)

In over 50 years of study I created several variants of devices for the contemplation of bi-optical images.

This is the latest design.

 

The device was executed in several copies of my friend Petrica Damian

   with bricolage tools.

I will distribute free to people who want to apply bi-optical techniques.

  If there are numerous requests, for obtaining such devices, I have to recommend a professional workshop.
