Hi’ again
The result is as follows:
Doing a standard fast export of 32 26MB NEF files takes 70 sec. on my HP Notebook with a i7 processor and a SSD disk.
Processing the same 32 NEF files not using the fast export option runs for 153 sec.
So fast export is faster, but the result of the normal (and fast) process is really very good and “reliable”, and you use your own profiles. Maybe you will have to be a photo freak to notice some small difference between this result and the result of further RT editing.
