Abstract

U završnom radu govori se o astrofotografiji. Objašnjava se proces izrade i

faze procesiranja astrofotografije. U teorijskom dijelu obrađuje se povijest

astrofotografije kao i njen tehnički aspekt (s naglaskom na ulogu RAW formata

i vremena ekspozicije). Ukratko su objašnjene tri glavne postavke fotoaparata:

otvor zaslona, brzina zatvarača i ISO osjetljivost. Također, navodi se važnost

bijelog balansa i vrste objektiva koji se koriste za različite motive u

astrofotografiji. Navode se metode snimanja i vrste astrofotografija koje se

mogu fotografirati tim metodama. U praktičnom djelu rada snimaju se autorske

fotografije zvijezda i obrađuju se u Adobe Photoshopu CC. Pri obradi i

procesiranju fotografija govori se o načinu smanjivanja šuma koji se javlja

zbog fotografiranja u uvjetima s malo svijetla. Cilj rada je objasniti metode

snimanja, karakteristike te način obrade amaterske astrofotografije.

Abstract (english)

This seminar is about astronomical photography. The process of making and

processing phases are explained. In theoretical part of the seminar, we will be

talking about the history of astrophotography and its technical aspect (with

emphasis on the role of RAW format and exposure time). Three major

exposure settings are explained in short: aperture, exposure time and ISO

sensitivity. The methods of photographing and types of astrophotography that

can be taken with these methods are as well explained. In the practical part of

the seminar, astrophotography will be edited in Adobe Photoshop CC. The

section about editing and processing of images writes about noise reduction

caused by poor lighting. The aim is to explain methods of making

astrophotography, its characteristics, and methods of processing.
