Abstract
Digitalizacija fotografske slike je prevođenje analognog signala u digitalni oblik, u užem smislu pretvorba trodimenzionalnog oblika nekog objekta u binaran kod zapisan kao računalna datoteka. Digitalni zapis fotografske slike nastaje tako da senzor mjeri svjetlost kao električni napon i nakon osvjetljivanja dobiva svoja obilježja, ton i boju i postaje piksel. Piksel ostaje nositelj informacija od trenutka kada fotografija nastane sve do izlaznog uređaja, u ovom slučaju medija realizacije. Digitalizacija fotografske slike sastoji se od njezina razlaganja u mrežu slikovnih elemenata. Fotografske slike su danas većinom u digitalnom zapisu, jer ih je kao takve moguće nebrojeno puta korigirati i prepravljati. Danas je na raspolaganju veliki broj vrsta digitalnih zapisa slike. Digitalni zapis može biti bez sažimanja podataka ili sa sažimanjem. Digitalni zapisi sa sažimanjem proizvode manje datoteke tako što odbacuju informacije o slici, pa komprimirana slika nije identična originalu, dok digitalni zapisi bez sažimanja podataka sačuvaju potpune informacije o slici. U ovom diplomskom radu biti će riječ o digitalnom zapisu fotografske slike i ispisu iste kroz različite medije. U praktičnom dijelu rada fotografske slike ćemo ispisati kroz različite medije, te definirati koliki je gubitak informacija za određeni ispis.

| Abstract in english: | The digitalisation of a photographic image is the translation of an analog signal into a digital form, in the narrow sense, the conversion of a three-dimensional form of an object into a binary code written as a computer file. The digital recording of a photographic image is created so that the sensor measures light as an electrical voltage and after illumination gets its characteristics, tone and color and becomes a pixel. The pixel remains the bearer of information from the moment the photograph is made to the output device, in this case the medium of realization. The digitization of a photographic image consists of its decomposition into a network of image elements. Photographic images are mostly digital today, as they can be corrected and modified many times. There are many types of digital image records available today. The digital record can be either without data compression or with compression. Compressed digital files produce smaller files by discarding image information, so the compressed image is not identical to the original, while digital files without compression retain complete image information. This work will concentrate on a digital recording of a photographic image and printing it through different media. In the practical part of the work of photographic images we will print across different media, and define how much information is lost for a particular print. |
