We could define a sequential contrast in the bioptical compositions, where the sequence is composed of two stages. In the first stage the conventional image appears containing certain stimuli and in the second, the image, deducted from the first, is taken by an optical device. In deducted image, when looking through a device, the effects are caused by activating stimuli.
There are 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, I detach some ideas of the cinestatism concept.
Some of my studies have as theme the optical possibilities of development in fine art. I cite, among others, the introduction in the compositions of fine art of the stimuli
resulting from graphic tests studied in Binocular Rivalry (B.R).
Test for B.R. is a unit composed of two different images: the left and right eye.
Tests B. R. composed of R.Blake (2001) were used in magnetic resonance research, achieving changes in the brain photographed image.
Subcortical Discrimination of Unperceived Objects during Binocular Rivalry
By entering, in, bioptical compositions, different stimuli resulting from research in the field binocular rivalry, together with the color fusion Helmholtz and 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. … image the forms appear as floating (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 bioptical class, in that it shows sequential.

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 Bălănescu 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).
The anagliphic 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.
