His interest in still-life by leading European artists ages 17-18, to the question "why looks Îáüåìíûå?" approached from a practical point of view. Ie I was not interested in the scientific explanation of the illusion Îáüåìíûå through applied sciences - physics or chemistry. The interest lay in the desire to understand what there is "smeared" the artist, in order to look Îáüåìíûå.

Dear sergejnowo! You slightly contradicted themselves. Can not understand "what did someone" to make it "look a certain way, not answering the question" why, he did just that, and not something else? " But the answers to the question "why" - and there is a problem for science, without some knowledge going. In this case, the benefits of science is that it tells others what they should do to create a similar effect. But you are right that the chemistry is not to blame.

This - all well-known axiom that people do not see the eyes and brain. The most compelling example - of a dream. I will not consider the illusion of volume - due to the complexity and incomplete theme is elaborated. Dwell long on the illusion of motion, which is based on the ability of the human brain: correct minor irregularities (in our experience and present) in the visible image. If, for example, an object that should be strictly vertical, and as such we have not seen, the brain begins unconsciously "dovorachivat" seared in him the image in the "correct" side. Studies have shown that this process is not instantaneous, and inertia: it runs at a speed of about 15 degrees per second. The reverse process takes faster, but also not instantaneous. It is necessary to bear in mind that by looking at the pictures we have at any one time can clearly see only a fraction of its area. If the viewer look at a certain speed slides across the image, then when hit with a distorted view of the normal image of the object, they are the first time "deployed" out of inertia in the opposite direction, creating the effect of motion. The direction of the gaze, as well as its speed (physiologically very large) must be driven by the will of the artist, depicting the "road" the various parts, engaging and delaying glance the viewer. Naturally, the source of distortion should not be large, ie they should not cause the effect of discomfort perception unprepared audience. Toulouse-Lautrec was a master of such illusions, but often still crossed that line discomfort, which, however, to a trained eye does not create big problems.

Here's an early picture of the Finnish artist Eino Ruutsalo (Eino Ruutsalo, 1921-2001) from 1946 (see ill. 1) when he, ex-fighter pilot, in search of work had gone to Sweden and working in an advertising agency, in addition moonlighting painting. Painting style typical of the later Ruutsalo, but in 1946, before the establishment of "kinetic art" was still very far away. But apparently, even then the idea of using optical illusions, which is fully manifested in ten years (see ill. 2), they possessed. The painting depicts a view of the cathedral in Uppsala with the "Iron Bridge". Striking unnatural inclination of the towers to the right. Yes, there's little artist "moved" with the slope, but if you look at the picture on the right at an angle of 40 - 50 deg. and the bottom at an angle of 10 - 20 deg. (counting from the normal), then this slope is corrected, but it begins to seem that the clouds are moving from left to right. (Actually many of the paintings produced a much better impression if you look at them is not strictly "full face", but at a certain angle, it seems to me that this fact requires serious analysis from the perspective of the issues raised in the discussion topic.) Such an effect of cloud motion there is a Titian, but, alas, can not now recall what specific pattern.

Could you lay out a typical job and to comment in detail?

The classic mistake novice artist. Etude written without departing from the canvas and at an angle, hence the failures in the figure and proportions. The author himself would probably have been glad Etude such profound conclusions. To the artists are not interested to hear what he really wanted to say his work: rolleyes:

Why the contradiction?
I am not interested in explanations /studies at the level of academic physics and optics.
I'm trying to develop the ability, with a glance at the painting, say that (he) or that (he).

Ok. Here are three works (the first illustration - detail). The first two attempts to portray the characters legs (La Goulue, Le Dezosse and Jane Avril) in motion. More successful, in my opinion, handed illusion quick movement in the first illustration (Dance in the Moulin Rouge, 1890). But the third illustration - just successfully demonstrates the illusion of slow motion (Jane Avril, emerges from the "Moulin Rouge", 1892). Pay attention to the vertical: they are all slightly tilted to the left, what contributes to the impression and the "grid" on the walls. The brain naturally seeks to correct this unnatural in terms of life experience of the slope, so Jane Avril illusory "moving" to the right, leaving the "Moulin Rouge". This illusory motion contributes to the direction of the hatch on her coat, and also elected as an artist diagonal composition, visually facilitating the movement is right (for the viewer-Europeans, accustomed to read and write from left to right and from top to bottom). The figures also left, which, incidentally, the view falls in the last turn (the brain by this time had "calmed down" after the overview figure, Jane Avril), "move" to the left, which again contributes to the direction of shading on the coat male.

Here's a comment I can make. But it is quite possible and a different view:

is in St. Petersburg this artist Jaroslav Gerzhidovich wrote a fairly large canvases 100x150, and the details can be studied with a microscope in the true sense .... that's like .... sorry no close-up photo

I am here this wonderful thing seems very authentic reality-nature-nature-the outside world: seen almost monochrome image of silver (as in life). Ie details at first do not rush with your eyes and do not interfere with the perception of the whole, and then, if you want, you can do gaze components.

Here is a strange optical effect:
(Artist Vadim Dolinsky-portrait Griboedova)

[олег назаров]

That's the genius of the effects ... Keith Haring .... one of the most favorite ..

if there are fans can make a separate topic I have many photos of his work

.. And the theme smoothly (and inevitable) flow into "Opt-Art "....
