Raw editing

  • Ok guys, as asked from Jonas i would give you some information about the RAW editing. I'm italian so my english it's not so good.
    First of all, as many of you know, the Lumia 1020, after the black upgrade, for each shot save 2 jpg and another file with .dng extension.
    As you can see from the file weight, the dng it's heavyest than the other 2 that are one in 5mp and the other one in 38 (or 34 mp, don't remember)
    If the 38mp jpg it's 2-3mb the dng it's 40mb and more.

    Here some information about the RAW files
    http://en.wikipedia.org/wiki/Raw_image_format

    Basically, in digital photography, the raw file it's like the negative for the analog photography. The most important thing of this format it's that it's not modified by a jpg conversion. Every jpg that you save from any camera it's a conversaion done by the software algorithm. Tha RAW file it's completely natural and it save a lot more information that can be very useful for an editing.
    This not mean that the original raw file look better than the jpg, because a lot of this information can be not so good for a photo, but the difference it's that it's a your own choice to remove them.

    You cannot view raw files directly with windows, and you can't modify them directly with editing software. For do this you have to open them with dedicated software.
    I use, for example, gimp for a long time, and was natural for me search some plugin for edit the dng files of my 1020.
    I found the answer in UFRAW.
    http://ufraw.sourceforge.net

    Ufraw it's a stand alone program that can open the dng files, in fact with ufraw you can totally edit the photo and use gimp just for a crop. Ufraw save the dng edited photo in a .ppm format that it's compatible with gimp.
    Here i will show you a couple of example of some original photo an the ufraw edited twin.







    Feel free to ask any kind of information, i'm still testing the raw editing, i'm not a pro just an amateur.

  • WOW!  This is great! I really want to enter in this "world" and start treating RAW/DNG images. Can you tell me what parameters you usually change while editing your RAW's? Where should I start after importing my DNG photo?

  • Thanks for the tips and samples.
    I want to give RAW a try ever since I installed the Nokia Black update, just haven't found time yet.

  • I'm giving a try to this Free Software: http://rawtherapee.com/ and it really looks great with a lot of options. If I master it, I might make a specific topic about it but I must confess that I'm not a RAW kind of guy...  :)

    Be good, do something good...start the day with a smile.

     

    How can I stop the loss of metadata when post-editing with photo apps?
