Abstract

Cilj i zadatak u ovom završnom radu jest objasniti uzroke šuma na fotografiji, zbog čega i kako nastaju, kao i o svim pojavama vezanim za šum na fotografiji. Šum se u digitalnoj fotografiji obično veže uz nešto nepoželjno i možemo ga definirati kao varijacija svjetline ili boje u slici, stoga je primarni cilj opisati postupke kojim bi mogli smanjiti, tj. reducirati pojavu šuma, odnosno kojim bi postavkama na fotoaparatu mogli smanjiti pojavu šuma na fotografiji. Proučavanjem raznih formata zapisa slika, a i zbog same obrade šuma na fotografiji, RAW format se ističe u odnosu na ostale formate zbog same mogućnosti dobivanja kvalitetnijih slika. Šum na fotografiji ima mogućnost pojavljivanja u različitim oblicima, digitalni fotoaparati proizvode tri uobičajene vrste šuma ovisno o duljini ekspozicije i ISO postavkama, stoga ih je važno navesti i okarakterizirati ih. U eksperimentalnom dijelu rada opisuju se mogućnosti šuma u RAW editoru, ovisno o proizvođaču, kao i uklanjanje šuma s fotografije u raznim programima za obradu fotografije.

Abstract (english)

The aim and task of this final work is to explain the causes of noise in the picture, why and how they came, and all the phenomena associated with the noise in the picture. Noise in digital photography usually associated with something desirable and we can define it as a variation of the brightness or color in the image, so the primary goal to describe procedures that might reduce, ie. reduce the occurrence of noise, and that would settings on camera could reduce the occurrence of noise at photography. By studying various formats on the picture, and because of the noise on the photo processing RAW format stands out in comparison to other formats because of the possibility of getting quality images. The noise in the picture has encountered in various forms, digital cameras produce three common types of noise depending on the length of exposure and ISO settings, so we were important to specify and characterize them. In the experimental part we describeabout the reduced noise in the RAW editor, depending on the manufacturer, or completely removed noise from photos in a variety of programs for processing photography.
