In addition to raw formats, cameras also offer the option to save your images as JPEGs. dng, of some raw file formats you’ll find out in the wild: dng converter and transparency about its specifications online. When you hear raw files being referred to as “digital negatives”, that is referring to this format, which Adobe created and made publicly available in 2003 to address the problem of the industry having no real open standard. dng file is the closest to a universal raw file format you’ll find. While there are some raw formats that are more universal than others, most camera manufacturers use their own proprietary raw image format. It also saves a copy of the adjustments that would have been made by your camera (so that your computer can have a starting point to work from), all of your metadata, a thumbnail, and often an additional JPEG version of your file, so that you can view it on your camera.īy comparison, when you save your images as a JPEG, your camera applies all of the adjustments and saves the final image, but does not keep the original, unprocessed data. When your camera is set to record in its raw format, it saves the original, unprocessed data. Instead, they change how the sensor interprets or manipulates the data that it records. None of these settings do anything to change how the light physically strikes the sensor. White balance, sharpness, contrast, saturation adjustment controls, and ISO settings are all part of this processing. What kind of processing needs to happen to that data? Think about all of the settings you can adjust in your camera that alters how your image looks. However, this data needs to be processed before it can be finalized as an actual picture. When a digital camera captures an image, the sensor records a mosaic of digital data including the values of each individual sensor pixel. Raw files contain the most complete, uncompressed image data, but in a form that is not directly usable and must be processed. We’ll help you decide if a raw file is right for you, and when you may and may not want to shoot raw. Typically you’re deciding between raw vs. As you start to get more serious about photography, you may wonder what file format to shoot in.
