Sažetak

Digitalni zapis fotografske slike, tj. informacije o bojama, definiran je kroz vrijednosti plavog, zelenog i crvenog kanala zapisa. Dosadašnja ispitivanja dokazuju mogućnost upravljanja percepcijom fotografske slike, primarno portretne, promjenama pojedinog kanala. Pri tome se kod portretne fotografije pokazalo da je za upravljanje percepcijom fotografske slike optimalno mijenjati vrijednosti crvenog kanala u granicama zadržavanja ikoničnosti. U radu se ispituje usporedba promjena kanalima koji definiraju komplementarnu boju u odnosu na promjenu vrijednosti crvenog kanala kod portretne fotografije.

Comparison of channels in relation color-complementary color on the portrait photography regarding red color

Abstract

Digital recording of the photographic image, i.e., color information, is defined by the value of blue, green and red channels records. Recent research shows the ability to manage the perception of the photographic image (particularly portrait) with changes in the individual channels. In portrait photography was shown that for the managing with the perception of the photographic image optimally is to change the value of red channel within the retention of the photo iconicity. This paper examines the comparison of changes of channels that define the complementary color with respect to the change in the value of the red channel at portrait photography.

Patrik Ervells latest collection is ironically titled “Software”ADIDAS ORIGINALS TUBULAR SHADOW. In the notes from the presentation, Ervell says he was interested in developing tension between nostalgia and sci-fi,NIKE ZOOM WINFLO 3 and even included 90s cyberpunk amongst his influences. Ervell developed this point of view by creating an imaginary software company called Idegen software systems. He then re-appropriated the company’AIR JORDAN XXXI MENs logo in several of the collection’s garments. Elsewhere,MBT TARIKI MEN mohair coats with oversized lapels made an appearance alongside mock neck tees,NIKE AIR JORDAN RETRO 5 police-inspired ribbed sweaters,MBT FORA GTX WOMEN flight bombers, and polyurethane leather coats. The setting was also suitably dystopian, and the resulting ambiance was something akin to if the creators of Deutschland 83 and Hackers met up and decided to create a collection… We mean that as a compliment.Yesterday afternoon,JORDAN CP3 IX MEN artist JR spent the day working on his latest collaborative piece with Daniel Arsham in Greenpoint,NIKE AIR MAX 90 Brooklyn,MBT KIMONDO GTX MEN NYC. Connecting the lines between art, architecture, dance and theater, Daniel Arsham has been known to subvert existing architectural structures in unconventional,NIKE CLASSIC CORTEZ NYLON playful ways; confusing and confounding the expectations of space and form.
