Research years ago led me to convert the cr2 files to dng as a way to save space. Typically when I upload from my data cards they are done so with my presets. Something did not trigger LR to import them as it usually does and imported them from the recovered SanDisk program as a jumble of Cr2 and Jpeg.īeing that my entire catalog is now dng I would like to keep the files consistent which is my only real need to do it. It is very possible it is 100% user error and that in my blurry eyed distress of the possibility of That LR v5.7 is giving me a error message only on the recovered files prompted the inquiry. Loosing a brilliant collection of shots from a amazing music festival weekend I failed to get it right. Thank you so much for making the time to dish out knowledge here on the forum. If you want DNG fine, mind you DNG can take more space, but not so much to be an issueĪnyhow, how about the inquiry's on what happens when you do not first convert to DNG, and when you copy outside of LR then import via ADD. If you can get the CR2 files working in LR, then they can later be converted to DNG. This may or may not be a Copy as DNG issue, it might be a image recovery issue.Īlso the inquiry to verify and post your working LR version. JimHess Can you explain more, thanks Jim. The 'Enhance' feature does run and create a second DNG file version. Very slight changes are obvious if I use Photoshop and the 'Difference' blend mode to compare the two DNG file layers. So it seems to work for me- with DNG files! Is that more than JPG? I have never known DNG to use more space than proprietary raws. I have known of problems where the photos were originally imported into Lightroom as DNG, but the recovered files are now in the camera CR2 format so Lr does not recognize them. (Changed Filenames would be a "Spanner in the works"!) The basic answer to this would be to use the (external) Adobe DNG Converter program to convert the recovered CR2s to DNG. I get a 'error file can not be converted' message. This would possibly mean that recovery has not been successful to fully re-build the data in the files. I use Nikon and Fujifilm and cameras, shooting raw files with lossless compression, which I routinely convert to DNG using the DNG converter before importing in Lightroom. The DNG files converted from Nikon NEF files are 15 - 25% smaller than the original raw files.
