Abstract

U završnom radu govori se o astronomskoj fotografiji. Objašnjava se proces izrade i faze procesiranja astrofotografije. U teoretskom dijelu obrađuje se povijest astrofotografije, važnost RAW formata fotografije te vremenu ekspozicije. Ukratko su objašnjene tri glavne postavke ekspozicije: otvor blende, vrijeme eksponiranja i osjetljivost. Također, navodi se važnost bijelog balansa te 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 mjeseca i zvjezdanog neba te se objašnjava način njihove obrade u Adobe Photoshopu. Pri obradi i procesiranju fotografija govori se o temperaturi boje, bijelim i crnim tonovima, sjenama, bijelom balansu, kontrastu i ispravljanju grešaka pri snimanju, kao i otklanjanju šuma. Cilj rada je objasniti i pokazati na koji način snimiti i obraditi amatersku astrofotografiju.

Abstract (english)

This seminar is about astronomical photography. The process of making and processing phases astrophotography is explained in it . The theoretical part deals with the history of astrophotography, the importance of RAW image format and exposure time. Three major exposure settings: aperture, exposure time and sensitivity are briefly explained. The importance of the white balance and the type of lenses used for a variety of motives in astrophotography are stated. 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, original photographs of moon and a starry sky are photographed and editing methods in Adobe Photoshop are explained. The section about editing and processing of images writes about the color temperature, white and black tones, shadows, white balance, contrast, and correcting errors in the recording, as well as the noise reduction. The aim is to explain and show how to photograph and edit the astrophotography as an amateur.
