[QUOTE="aroy, post: 325793, member: 16090"] There are two methods of applying the edits to the file 1. Modify the file using edit commands, but keep a log of all the commands. This may be in a separate file or in the same file. These are called non-destructive edits, as the original file remains as it was, and every time you open the software, it applies all the edit commands to display the file. Capture NX-D uses a separate file for the edit log, while some software embed the log within the NEF file while saving it. 2. Apply all the edit commands to the file and save only the final version. This is destructive edit, its only advantage is that the file is small and every time you open it it opens fast as there are no operations required. SDK for file manipulation is available. Some times the manufacturer publishes them, some time third party, but they are available for developers who want to use the RAW files. Any way, once you can read the file you can also write it back.
