But they do NOT relate to underlying image data, the raw of the RAW if you will. I've seen folks run diffs on the metadata, and there ARE differences. I'd also like to see what metadata is lost. If Canon can drop support for its own cameras, it would be no surprise if, some day, ACR no longer supports old file formats, and DNG will sure look good then. Canon has done exactly this, and you will need multiple versions of DPP to edit all of your files if you have images from both older and newer Canon cameras, as I do. Of these, one resonates with me, and that is camera manufacturers who drop support for older RAW formats in their software. In Adobe's specification document for DNG they briefly list the advantages, as they see them, of DNG. There is no loss of image data, at least in Adobe's conversion. However, I suspect that the perception of lost data comes from DNG's use of lossless compression, and the stripping of some proprietary metadata that is used by the camera manufacturer's RAW converter and editing software, and not needed in, nor compatible with, a cross-platform format. As far as I can tell, claims of DNG data loss are primarily found on user forums, with the associated reliability of those claims. As an open specification, parties other than Adobe develop DNG converters, and I would not be alarmed to learn that one or more of those programs screws things up.
Official descriptions of DNG describe the process as lossless. I would be very pleased if a reference to an Adobe source (having developed and promoted DNG, they would know) outlining the loss of data in DNG could be provided.

Once converted to DNG to obtain software compatibility, what is the purpose of hanging on to the original? DNGs contain all of the data present in the original format, and behave exactly like the originals in editing. Other than the time it takes to convert the original RAW format to DNG, there is no disadvantage to DNG compared to the original format. I also don't quite understand the aversion to DNG files. I hope they don't, but then I wish they hadn't made a number of decisions that they have recently made. Does anyone feel completely confident that Adobe is incapable of making such a decision? I would not be in the least surprised if Adobe dropped support for older cameras at some time.
Right now, the current version of Canon's DPP does not support files from three of the five Canon bodies I have owned (350D, 30D, 40D), among many others. You would have to have multiple versions of the software, with different features and capabilities, in order to edit all of your files. This means that if you wanted to use the latest and greatest version of such software with files from your old, now unsupported, camera, as well as your new, supported camera, you would be out of luck. I was hoping someone here has a good ideaĪ bit tangential, but since the issue has been raised in this thread.One reason why non-fools might convert native RAW to DNG is that some software programs drop support for older RAW formats in more recent versions. I've asked Adobe FOUR times about this, and they keep ignoring (only!) this question. It's not the first time Adobe refuses to add camera support to Lightroom, but keeps updating DNGconverter. So how do I do this? Surely, this has to be possible. I'm actually having trouble keeping them in one place because the collection is just simply getting too big. Keeping DNG is also not an option, because they are horribly inefficient, doubling every file in size.
There are thousands of them, so copying over all edits of all files, and all tags and metadata and whatnot, is simply not an option. I can convert the DNGs back to RAWs alright, but Lightroom is going to see those RAWs as new (unedited) files.

Now the problem arises how to migrate my existing, edited DNGs back to RAWs without losing edits. Now that I'm updating to Lightroom 6 (because Adobe refuses to add camera support to Lightroom 5, those nasty youknowwhats) I get my camera supported. I converted them by embedding the original RAW. This isn't supported by Lightroom (although it is by Photoshop, inexplicably) and therefor I needed to convert each and every picture to DNG before being able to do anything with them in Lightroom. I have Lightroom 5 and bought a new camera, the Olympus OM-D E-M5 mark II. How do I migrate DNG files back to RAW without losing edits?
