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 additional highlight detail, but rarely more.
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 typically capture 10, 12 or 14 bits of data for each pixel, and this is then processed down to produce regular JPEG photos (8 bits) or converted into high-quality 16-bit TIFF files.
