The only clear advantage it presents is that it bypasses the time delay between a new camera body and the updating of the most used software to read the raw file. Since it was half a decade ago it might be somewhat outdated but I have not heard anything to date to convince me to reverse my original opinion that dng did not present any clear advantages for the long term. I collected opinions online and tabulated them and wrote up the results at. Why do you import the raw file and save a copy as dng?Ībout 5-6 years ago I was wondering if it was worth going to dng. I've gone back in my archives and resurrected a few of those that are now hanging on the walls of my home gallery.For belt and suspenders image backup. What could have been a portfolio shot ends up being slightly out of focus, suffering from subject motion blur, or camera shake when we zoom in or is too small due to a large crop. If for some reason I lose an original, I have the dng backups. The reason I keep all my original raw files is because PP software gets better and better with every new release and some very good images with technical flaws can now be saved. I've gone back in my archives and resurrected a few of those that are now hanging on the walls of my home gallery. Those images I chose to PP go to a directory on my C: drive. That's when I delete the images on my mem card and I will remove the worst of my dng images in LRc as part of the sorting process.
I import from rawimagestorage into LRc and have it make a dng of each image on a separate LRc working drive SSD as part of the process. I copy my camera mem cards containing the raw files to a separate "rawimagestorage" SSD on my PP computer. Why do you convert to DNG, no need for that.įor belt and suspenders image backup.
