More likely he will figure out that RAW is good for maybe .009% of his photos, and he will find he never diddles with the RAW, and he will forget the whole concept of keeping RAW well before he ever needs the space. In which case his inode calc will be off by a huge factor.
NOT! I may produce more than one JPG from the RAW, or I may not even produce one. The RAW is the archival, contains the most information. The transformations that darktable makes to produce the JPG are described in the XML files. I can delete the JPG and get it back from the RAW+XML I use RAW as a generic term for the cameras native mode dump of the sensor. That's why it contains the most information. Right now each camera vendor has their own RAW format, though there is pressure on for a camera independent standard, DNG http://en.wikipedia.org/wiki/Digital_Negative Low end cameras, the point and shoot type, produce JPG directly and have a number of 'scene' settings which process the sensor information according to one of a number of formulas. JPGs are lossy and the transformation looses information that is available at the sensor level. The RAW file is not lossy. It leaves the choice of transformation, perhaps multiple different transformations, to the "digital darkroom" software such as darktable. This is a lot more capable than the software in the camera. There are many web sites that illustrate how different information can be made on the same raw image, as well as all the traditional 'darkroom' techniques such as cropping, dodging, spotting, and many more, such as noise reduction, colour standard translation, tone mapping and others that the camera cannot perform. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
