james_alexander Posted May 11, 2004 Share Posted May 11, 2004 Is "RAW" an acronym or a word? If it is an acronym, what does it stand for? If it is a word, why is it written in all caps? Link to comment Share on other sites More sharing options...
zapped Posted May 11, 2004 Share Posted May 11, 2004 It's a word, and it refers to the data taken directly from the camera's sensor. The RAW file must be run through software to transform it into a viewable Tif or Jpg.<br><br> More <u><a href=http://www.dpreview.com/learn/?/Glossary/Digital_Imaging/RAW_Image_Format_01.htm>here</a></u>.

peter_phan Posted May 12, 2004 Share Posted May 12, 2004 It's a word, and it's in all caps to differentiate it from the word "raw", which can be used to describe all kinds of things. But "RAW" refers to the digital image format. <p> RAW = a digital image format <br> raw = a state of being uncooked (as in food) Link to comment Share on other sites More sharing options...
jbq Posted May 12, 2004 Share Posted May 12, 2004 It's a word. It refers to the data being raw, i.e. unprocessed, i.e. the digital data as it was at the very first digital stage. It's often written in caps because pretty much all the image file format names are acronyms (JPEG, TIFF, GIF, PNG, PSD...). Link to comment Share on other sites More sharing options...
gaius1 Posted May 12, 2004 Share Posted May 12, 2004 Also note that a RAW file will actually have a file extension like .CRW (Canon) or .NEF (Nikon). Just to confuse matters further :-) Link to comment Share on other sites More sharing options...

mike sisk Posted May 12, 2004 Share Posted May 12, 2004 Y'all are missing the point. The original author is likely a grammarian "stickler" and wonders why -- as do I -- we're incorrectly writing "raw" in all caps. Things like JPEG (Joint Photographic Expert Group) or TIFF (Tagged Interchange File Format) are easy to explain -- RAW just ain't right. But, it looks like we're stuck with RAW just like we are with "8 Items or Less". Link to comment Share on other sites More sharing options...

james_alexander Posted May 13, 2004 Author Share Posted May 13, 2004 Mike, you are exactly right. I would prefer to think that I'm a stickler for clarity rather than a stickler for grammer, but in either case it appears that I lose in this instance. Peter, lots of words have more than one definition but we don't normally indicate a specific definition by writing in all caps. Jean-Baptiste, as I understand it "RAW" is not a specific file format like JPEG or TIFF, but more a category of file formats. This seems to make about as much sense as writing "COMPRESSED" when we're talking about JPEG files or "LOSSLESS" when we're talking about TIFF files. Oh, well. So much for clear thought. Thanks everyone for the comments. Link to comment Share on other sites More sharing options...
jbq Posted May 13, 2004 Share Posted May 13, 2004 James - Contrary to what you will believe, I am not trying to confuse you any further. JPEG is actually a family of compression formats, some lossy, some lossless, some 8-bit, some 16-bit. What we often call a "JPEG" file is actually a JFIF file with YUV/DCT/Decimated/Huffman JPEG data. JFIF is a file format. TIFF is a "meta-format", which can contain data in many different formats. Typical formats are 8- and 16-bit uncompressed, or compressed with LZW/LZ77, but JPEG data is also an option, and I'm sure that there are plenty more. Now, de-facto usage has been that JPEG are almost always used in lossy 8-bit applications, and TIFFs in 8- and 16-bit lossless applications, but that's a usage habit, not a standard.

kelly_flanigan1 Posted May 13, 2004 Share Posted May 13, 2004 A seminar I went too in 1996 said there are over 200 variants of the TIFF format. Here we on odd occasions still get weird TIFF files that cannot be opened on modern Photoshop veriosn; open on Photoshop 3.0 . RAW is an old format; it can be only 1 byte per pixel; and used in DOS. There was/is a DOS program that opens RAW files by Jih-Shin Ho ; used for slide shows; batch; contact sheets; and file conversions. Link to comment Share on other sites More sharing options...
peter_phan Posted May 15, 2004 Share Posted May 15, 2004 James, these explanations may offend your grammatical sensibilities, but that's just the way it is. After all, computer engineers think this stuff up, not grammaticists or linquists. It could be that the origin of RAW is as simple as, "Well, it's raw data, so why don't we just call it RAW, making it all caps to coincide with the caps convention seen with JPEG and TIFF?" There are all kinds of techno-geek words that have arisen from such simplistic sensibilities. Say what you may about these explanations, but its pretty unaminous that RAW does not have any acronym associated with it that would explain it being written in all caps. It's basically in caps because TIFF and JPEG are in caps. Link to comment Share on other sites More sharing options...
mike sisk Posted May 15, 2004 Share Posted May 15, 2004 Actually, many scientists, engineers and programmers are sticklers for grammar; being that such endeavors require clear and concise communication. Although I'm sure an exception exists, I can't think of another term akin to RAW in computer science that's not either an abbreviation, acronym, or trademark.

steve_muntz Posted May 17, 2004 Share Posted May 17, 2004 I think the reason it's capitalized has more to do with marketing departments than anything else. Fuji has .RAF files, Nikon has .NEF files but they're both RAW files. I'd say RAW is a type of file, it's not a standard like TIFF (or the many variants as stated above). Nikon, Canon and Fuji RAW files all work a little differently and you need their software to work with these files - although now they can be read by Capture One (some types) or Adobe Photoshop CS (most types) as well.
