Perspectives entocentrica, telecentres, hipercentrica used in optical calculation, as in the fine art techniques.

Entocentrica perspectives, telecentres, hipercentrica are known (from specialized publications)    and applied on a case by professionals optical calculation.

 In the book, Liviu Iliescu " Elemente constructive și ansambluri optice sns pag .  96…97; 1977 Bucharest Technical Ed"

I quote from the manual:

  ………

 Some artists already applied perspective hipercentrica (Fig. 42),

  vanishing point  which is behind the observer.

Entocentrica perspective appears in telescopes causing compression effect depth of space.

Telecentric perspective is similar Cavaliera perspective.

  Hipercentrica perspective appears from observing objects through loupe (so the objects thumbnails), resulting entocentric perspective reversal

At the proposal of Prof. Dr. Cătălin Bălescu by the expansion optical means for fine art, describing the target, I have experienced the effects of perspective in building a camera lucida type, attached in turn a telescope or a loupe .

  I I'm having concern for extrapolation optical useful in fine art, I propose a paraphrase on philosophical thinking:

nihil est in structuram artis quod non sit prius in sensu

But reality occur adjacent combinations of communication resulting effects of emotional states,
