| RAW Format Written by Douglas Allchin, on Sunday, 06 January 2008 at 07:54  Hi! The RAW format (which just means unprocessed data as captured by the camera) is held different file formats usually by manufacturer (though often by individual camera in a given maker's range) there is also a suggested 'cross manufacturer' format, supported by Adobe - the famous DNG RAW. Using raw means that rather than relying on the manufacturer's in camera processing for colour balance, sharpness, contrast etc. you get the whole thing, warts and all in a RAW file, and usually adjust the colour (white) balance contrast and brightness then save the file and work on the rest using your favourite photo program. Most like Photoshop have both functions, and when one has finished with the RAW image it is saved out as a JPG or TIFF for more processing (levels etc cropping, perspective or lens correction etc.) NEVER make any changes to bthe original RAW file. That's your 'digital negative' always back up these straight from the camera and work on copies!!! Hope this helps? All the best! |
