![]() Raw files can’t be edited – you can’t make permanent changes to them in the way you can with other image formats. Expert photographers will often have a favourite raw converter in the same way that traditional film photographers would have a favourite developer. ![]() Adobe Camera Raw, Capture One Pro, DxO Photolab and a host of other tools will all produce different renditions of the same raw file. Raw files can’t be edited – you can’t make permanent changes to them in the way you can with other image formatsĭifferent raw conversion tools produce very different results, too, which is why it’s often more useful to think of raw files as ‘undeveloped negatives’. DNG raw file format, and while it does offer a free DNG converter to convert any proprietary raw file into this format, the DNG format has not really caught on and has itself come in different versions over time, so that not all programs that support the DNG format can read all the various DNG versions. RAF suffix, for example.Īdobe has tried to produce a universal. Raw file technicalitiesĪnnoyingly, each camera produces its own particular raw file type, so if you use third-party raw conversion software like Adobe Camera Raw, Lightroom, Capture One or DxO PhotoLab, you might have to wait a few weeks for support for a new camera to arrive.Įach maker uses different file extensions for their raw files. If you have a raw file, you can 'develop' it to deliver a much pleasing result using software like Adobe Photoshop Lightroom. But they contain a lot of useful extra data, so it’s possible to extract a wider range of tones from your photo ( dynamic range), select a white balance setting later rather than at the time of shooting, and apply heavier image adjustments without degrading the image quality. These raw files must be processed by raw conversion software before they can be viewed, edited or shared in the normal way, which is inconvenient. It's best to see them like a digital negative, while a JPEG is more like a 6 x 4 print from a high street lab. More advanced cameras, however, can save the camera’s original unprocessed ‘raw’ file instead of a processed JPEG image, or both at the same time. A lot of this excess data is discarded as the camera applies settings you’ve chosen on the camera, such as the white balance or picture style, and because the JPEG image format simply can’t hold all the data captured by the sensor. JPEG is a kind of universal file format for photos, that doesn’t take up much space and can be viewed and shared on any device.īut the camera’s sensor actually captures a lot more data than you see in the JPEG image saved by the camera. These are ready-processed image files ready for viewing, sharing and printing. So what’s the difference between raw files and the JPEG images produced by your camera? All digital cameras can produce JPEG images. They have been called the equivalent of a ‘digital negative’, but it would be equally accurate to think of them as the ‘undeveloped’ digital image. Raw files are unprocessed image files captured straight from your camera’s sensor.
