You may extract the original file from the dng file (to extract such a file, activate he button Extract at the bottom of the conversion dialog box).Ĭlicking Convert initiates batch conversion.
Original Raw File ► You may embed the complete and original RAW file into a dng file, essentially making dng into a wrapper for your RAW data. Additionally, file size increases by about 60 to 300 % (the linear version holds RGB data, while native RAW format stores but one pixel value per sensor element). In doing this method, some potential of your RAW negative is lost if you want to go return to the original RAW data. Converting to a linear form actually performs an interpolation of the Bayer pattern (exception: RAW files from a camera with a Foveon-based sensor). As significant improvements were implemented in the past couple of years, more may be expected. As improvements in the Bayer pattern interpretation (also called demosaicing) come along, you still retain original data and may apply any improved algorithm to that data. In most cases, the first method is preferred. Image Conversion method r There are two ways to do the conversion: retaining the original RAW data - usually the data of the Bayern pattern sensor data - and a conversion to a linear picture. Clicking on Change Preferences brings up the following dialog box:Ĭompressed r should always be used since it is a lossless compression, reducing about 10-65 % from files sizes. Tion © specify, how the conversion will be done. Parameters of section ® define the naming conventions of the newly-generated dng files. Section © indicates where the generated dng files will go. In section 1, you specify the folder in which RAW input files requiring conversion reside. The interface is uncomplicated, and you will be wise to keep in mind, that its task is to convert an entire folder of RAW files, not just a single one. dng J Document Name rĬompressed (lossless) Preserve Raw Image Don't embed originalġ Figure 9-1: DNG dialog to convert a complete folder of RAW files
