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 an example of yet another reception, allowing visually enlarge the image sharpness. Pathbreaker it is El Greco. It is mainly written for the churches, and his paintings were to be placed at a distance from the audience. Clarity hits brightness while visually weakened. To enhance the apparent sharpness of the sharp transitions from light to dark El Greco additionally increased the contrast, darkening of the dark and lightening of the light. This method also led to an apparent increase in the volume, because the light seems closer.

In this technique in the future has developed an interesting fate. For 300 years it was almost forgotten, rarely used by artists such as Canaletto. But since the beginning of 1930 he experienced a rebirth: he is actively used by photographers to enhance the visual sharpness of edges in images. This print jobs to put together two frames: one - the original negative, and the second - double-positive with a very pale, fuzzy and slightly defocused image. This technique, called then "blurred escaped" was revived for the third time today, reincarnated in the form of a filter (unsharp mask) in the program Adobe Photoshop, using for the same purpose (improving the visual field) but in digital photography.

But I can not fail to note that the "wider audience" it was possible only after 1931: after the publication of PG Van Zittert work, reveal the inner essence of the reception. The real work was devoted to the first practical suitability of the method of solution of integral equations of convolution type, now called the method of van Zittert (very, very serious mathematics). A compelling example of how science is done know-how of the great masters to the public.
