How to save RAW files?
Locked

I've got .nef and .cr2. What's the best way to Save As during editing?
That is, how do I save them so I can continue editing them in RAW? I've tried saving them as nef and dng. But digikam can't open the new saved files. "Failed to load image" Tiff, ppm, png? Is nef or dng supposed to work? sean _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

My point of view: Never ever change your raw files. They are your negative. So keep them save and unchanged. My way of handling is to use an software which is capable of handling configuration files (like recipe) where all settings are stored, so I can change one parameter and let the other alone. I use ufraw for this, but rawtherapee can be used as well. > > I've tried saving them as nef and dng. But digikam can't open the > new saved files. "Failed to load image" > > Tiff, ppm, png?

I thought dng at least was supposed to work. But if I save a file in dng, neither digikam nor ufraw can open it. sean _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

So I want to save the file > after I do those adjustments. As I said before: My way of handling is building up a recipe what to do with the file. Sadly digikam does not support something like this. If, for example, I want to refix the white balance, I simply change the white balance in the recipe and generate a png (or what ever I want). Ufraw may be not that easy in handling, but it does what I want it to do. Btw, have you ever tried rawtherapee? > > >> I've tried saving them as nef and dng.

Anyone knows if is there any open wish on BKO for it? I didn't find anything for it. I'd really like if the same "recipe file" could work the same in digikam as in ufraw. regards gerlos -- "Fairy tales are more than true, not because they tell us that dragons exist, but because they tell us that dragons can be beaten."

You cannot really "edit" in RAW, you can only influence how RAW is converted to RGB bitmap, which can be edited as usual. It may help you to google for some articles about RAW format and its conversion to RGB bitmap. Some programs allow saving "recipes" (a separate file), which is just a list of commands for the RAW converter about how to do the conversion. The RAW remains untouched. digiKam does not support "recipes". > Tiff, ppm, png? Is nef or dng supposed to work? TIFF, PNG, PNM, etc. are for saving RGB graphics. NEF or DNG are RAW formats and it is not possible to save RGB graphics back to RAW format. You can convert many proprietary RAW formats to DNG to gain the benefit of storing metadata (keywords, etc.) directly in DNG and have the same format for all your RAW pictures, however, the DNG is not the same as the original RAW anymore. Because of this, I personally do not use DNG. Apart from conversion to DNG, you can also keep the original RAW file inside of DNG, but it basically makes the file twice as big.
