Some cameras now let you process RAW images and save them as new JPEG files on the memory card. That might sound a bit pointless when you could shoot JPEGs in the first place, but it does mean you can try out different white balance settings, picture styles and more.
Cameras with the ability to shoot RAW files will almost always offer a RAW+JPEG option too. Here, the camera shoots a single image but saves two versions – the RAW file and a JPEG processed and saved with the current camera settings. The JPEG is useful because you can share it with other people straight […]
Usually when you take a picture the camera will process the data captured by the sensor into an image file. More advanced cameras can save the image in its unprocessed state – a RAW file – so that you can do the processing yourself later on your computer.
Software that processes RAW files from a camera and converts them into regular image files. Not all RAW converters are the same. The closest analogy is the different developers used to process film. Examples include Adobe Camera Raw, Capture One Pro and DxO Optics Pro.
Most digital photos are shot as JPEG images. This is a universal image file format that uses sophisticated compression to keep the files small and manageable. JPEGs are created by processing the RAW data captured by the camera. Some cameras let you save these RAW files instead. The files are larger and you need to […]
As well as saving JPEG photos at different sizes, cameras also offer different quality settings like ‘Fine’, ‘Normal’ and ‘Basic’. Fine produces the best picture quality and is the one to go for if you can. If your camera shoots RAW files, this is where you’ll find the RAW option.
When you shoot RAW files there is often a little extra highlight detail in the data than is initially visible, and a good RAW converter will be able to recover this detail to correct any ‘blown out’ areas. There’s no much margin for correction, however – typically you might be able to recover 1EV of […]
This is a handy free tool you can download from the Adobe website for converting digital camera RAW files into Adobe’s generic DNG format. It’s useful if you have a new camera but an older version of Photoshop, Elements or Lightroom that won’t open its RAW files.
A terms used by some software companies, for example Serif in its Affinity Photo software, to describe the RAW conversion process, where a RAW file is processed into an editable image.
‘Bits’ are the basic building block of digital data, and the more bits of information used in digital images, the subtler the colours and tonal transitions. Bits and pixels are related, in that the greater the ‘bit-depth’ used to create a pixel, the better the quality of the colour/tone information in that pixel. Digital cameras […]
Software that works alongside Adobe Photoshop to open and process RAW files before they open in Photoshop itself. Adobe Camera Raw’s tools are also built into Adobe Lightroom. Most people use Adobe Camera Raw to process their RAW files simply because they’re using Photoshop or Lightroom, but other RAW converters are available.
The ‘bit depth’ of RAW files is a factor in the picture quality they can produce, so this is a selling point for advanced digital cameras. Some cheaper models can only shoot 12-bit RAW files, but while this sounds like a small difference, the extra bit depth potentially offers 4x the image data so 14-bit […]
