Sažetak

Dinamički raspon fotografi je ovisan je o dinamičkom rasponu scene, dinamičkom asponu fotografskog aparata, tehnici snimanja, obradi digitalnih zapisa fotografi je i dinamičkom rasponu tehnike i medija realizacije fotografi je. U izvornom smislu, HDR fotografi ja podrazumijeva sliku čiji dinamički raspon odgovara dinamičkom rasponu scene. Kako je dinamički raspon snimane scene, u pravilu, veći od dinamičkog raspona fotografskog aparata HDR fotografi ja se danas najčešće realizira snimanjem scene različitim ekspozicijama te stapanjem tako dobivenih digitalnih zapisa u HRD fotografi ju. Samo se stapanje provodi različitim programima koji omogućuju i mapiranje tonova iz širokog dinamičkog raspona HDR fotografi je u uži dinamički raspon koji omogućava tehnika i medij realizacije. U radu se analizira utjecaj odabira programa na postignuti efekt reproducibilne HDR fotografi je.

Abstract

The dynamic range of photography is dependent on the dynamic range of the scene, dynamic range of photographic camera, recording techniques, processing of digital images and the dynamic range of technique and medium for realization of photographs. In its original sense, HDR photography involves dynamic range of image which corresponds to the dynamic range of the scenes. As the dynamic range of the recording scene is, in general, larger than the dynamic range of the photographic camera, HDR photography is commonly realized by the recording the scene with diff erent exposures and merging of the resulting digital records in the HRD photograph. Merging is implemented by various programs which allow the mapping of tones from a wide dynamic range of HDR photographs in a narrower dynamic range which allows the medium and technique of the realization. Th is paper analyzes the impact of the selected program on the achieved eff ect of the reproducible HDR photograph.

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.
