    Default Keeping RAW

    Just curious, do you guys keep RAW file. I mean native RAW file as like Nikon.NEF or Canon.CRW. OR just convert into .DNG

    I convert to DNG when importing to LR. Since the image data are not changed no point keeping the old Canon format files.

    So can I assume that NEF/CRW file and DNG file is both identical except in format?
    If yes then I might discard my NEF file that had been converted to DNG.

    1. Download files from CF card to harddisk
    2. Import into LR
    3. After checking that all files are ok, format CF card
    4. Adjustments in LR
    5. Export to web or jpg for printing
    6. archive files on 2 separate HD

    i dont see a real advantage of DNG over NEF. To process a NEF you do not rely only on Nikon software, there are plenty of other converters such as LR to convert from RAW to jpeg, usually the same software is also used to convert DNG to jpeg. So converting to DNG is just another step that takes time and effort which i can avoid.

    I'm curious why others aren't following Pentax's example of offering users the option of DNG RAW files when they shoot.

    Because the RAW files contain more than just the image: focus points, camera settings, picture styles .. GPS data if available. All this requires co-operation among the camera manufacturers to define a standard. How likely is that?

    I shoot in NEF. Just like negatives. Processed it with NX2 but the original NEF is left intact. Let's say in 2090, if I wanna re-process the NEF, it's still like I shot it in 2010. On condition, both the NX2 and I are still around.
    In short, keep all your RAW. You may not know when you need it again as JPEGs will degenerate (or self-destruct). Also, storage is relatively cheap. (A friend once showed me an original receipt issued by IBM Australia in 1961 for almost almost A$1 million for 5 megabytes of storage)

    JPG degenerate? Interesting theory, can elaborate further? What kind of "time bomb" is there embedded?
    What if your condition "NX2 still around" is not fulfilled? DNG as open standard has good chances to stand the test of time, proprietary formats can disappear any time.

    This is what I read on Lr books/Guide, and thats why I convert to DNG. But for the moment I am keeping my NEF.

    NEF= From Camera.
    DNG= Converted into Lr (before edit) Full size (resolution).
    TIF= After edit in Lr or CS (Original resolution).
    JPG= Resize to (depending on purpose like web or print or wallpaper)

    Am I doing in a sensible flow or am I not effecient. Any advise on my Workflow?
    Cause I am basically keeping 4 formats with a single photo and thats quite alot of space (especially NEF and DNG). For now still ok but over the time space issue will arise.

    Interesting thread you have started, Dark Matter.
    Like some of the CS-ers have mentioned, I convert all my CR2 into DNG and keep everything as DNG.
    I still haven't developed the habit of saving in TIFF, though I know I should.
    But more often, I keep them in .PSD format.
    Final version then I save in JPG.

    For all that additional data, isn't that what EXIF is for? Still learning here.

    jpeg: he might refer degeneration due to repeated saving of the file or repeated compression. Regarding dng. You need a third party software for the conversion. The same 3rd party software is also doing RAW to jpeg conversion. You don't need cam manufacturer software. I guess you can assume that supports the conversion today will also support it on the future.

    My DNG file only at average 17mb. and my TIFF about 5.5mb only. Why such big different. ?
    Did I do something wrong?? Am using D90.
