Lightroom and Capture One offer HDR tools with a difference. They don’t create wild and exaggerated HDR effects. Instead, they create what I would call DNG ‘super-negatives’ with extended dynamic range that you can then exploit however you like.
Bits and bit depth
‘Bits’ are the basic building block of digital data, and the more bits of information used in digital images, the subtler the colors 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 color/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.
Almost any photographic expert will tell you that you should shoot RAW files not JPEGs, and that RAW files are innately superior. The trouble with this kind of wisdom is that it’s repeated and passed on without question.
Many photographers prefer to work with RAW files – but what are they, how do you work with them, and why are they so much better than regular in-camera JPEGs?
The DxO Nik Collection 3 brings non-destructive editing to the Nik plug ins for the first time. This is how it was done, and what you need to know.
Bit depth is an important concept in digital imaging if you want the best possible image quality and if you intend to manipulate images heavily.
Most serious photographers prefer RAW files to JPEGs. They take more time and storage, but the payback is greater quality and flexibility. It’s not a one-sided argument – JPEGs have some advantages which are obvious, and some which are not – but here are six important reasons why RAW files are the way to go […]
