Abstract

Postoji mnogo formata za pohranu slika te stotine softverskih programa za njihovu konverziju. Tri najčešće korištena, i najvažnija za sveopću upotrebu danas, su TIFF, JPG (JPEG) i RAW. Postoje dvije vrste sažimanja podataka: bez gubitka i s gubitkom podataka. JPEG je zapravo komprimiran način pohranjivanja podataka koji rezultira gubitkom na kvaliteti slike. RAW datoteke, naprotiv, također nazvane digitalni negativi, bilježe sve podatke koje je digitalni senzor zabilježio. RAW format omogućava mnogo veću kontrolu nad konačnim izgledom fotografije ostavljajući mjesta za izmjenu slike. Prednost snimanja u RAW formatu je da se nakon snimanja mogu mjenjati mnogi parametri kao što su bijeli balans, zasićenost, oštrina, kontrast itd. Druga prednost snimanja u RAW formatu je da se može obaviti pretvorba u 8-bitne ili 16-bitne TIFF formate. Svaki fotoaparat koji podržava snimanje u RAW formatu dolazi s odgovarajućim programom za konverziju raw podataka u standardne RGB slike. Postoji mnoštvo drugih RAW konvertera koji omogućuju pregledavanje i obradu raw fotografija, kao što su Phase One's Capture One, Bibble Pro, Adobe Camera Raw i dr.

Abstract in english:	There are many image file formats and hundreds of software programs capable of converting images. The three most common image file formats, the most important for general purposes today, are TIFF, JPG (JPEG) and RAW. There are two types of image file compression algorithms: lossless and lossy. JPEG is basically a compressed method of storing data that results in some loss of quality. RAW files, conversely, often referred to as a digital negative; retain all of the information exactly as it was recorded to the camera image sensor. RAW format provides far more control over the final appearance of the image by allowing many changes to be made. The adventage of shooting a RAW file is that you can change many of the shooting parameters after exposure such as white balance, saturation, sharpness, contrast etc. A second advantage of shooting a RAW file is that you can also perform the conversion to an 8-bit or 16-bit TIFF file. Cameras that support RAW files typically come with proprietary software for conversion of their raw image data into standard RGB images. There are many other "raw workflow applications" designed to provide efficient processing and postprocessing of raw images, such as Phase One's Capture One, Bibble Pro, Adobe Camera Raw etc.
