1 Shot HDR

Quick rundown on various methods of adjusting tone and color in Darktable. Then a sneak peek at my 1 shot HDR technique.

In the video I start with a quick survey of different Darktable modules that you can use to set exposure, gamma, color balance and saturation.

With this week's Edit My RAW I get to use an experimental technique I'm working on for challenging captures. It's a lot like a single shot HDR, but with a wide range of applications. The enfuse command line I use in this video is:

enfuse-mp -o hdr.tiff –exposure-weight=1 –entropy-weight=0 –saturation-weight=0 *

    enfuse -o hdr.tif –exposure-weight=1 –entropy-weight=0 –saturation-weight=0 *

    (my mistake : -entropy)

    Thank YOU!!!

  2. Dear Harry!
    You time is gold.
    Thank You!

    Only enfuse also not work.

    star@star:~$ cd hdr2
    star@star:~/hdr2$ ls
    _MG_2011_01.tif _MG_2011_02.tif _MG_2011.tif
    star@star:~/hdr2$ enfuse -o hdr.tif –exposure-weight=1 -entropy-weight=0 –saturation-weight=0 *
    enfuse: unknown option “-e”
    Try “enfuse –help” for more information.

    But in life there are more important issues.
    Perhaps this is the problem of my computer.
    I look forward to new lessons.

  3. Dear Anonymous!
    Thank You!
    I install sudo apt-get install enfuse.
    All right.
    But again does not work.

    Where is problem? Where is mistake?
    Ubuntu 16.10
    Darktable 2.0.5

    • It looks like enfuse installed properly. Sometimes you need to type

      > rehash

      after installing a new package so that it shows up in your PATH. Also, maybe the package was only for enfuse and didn’t include enfuse-mp? You can just replace enfuse-mp with enfuse in the same command line.

  4. Dear King of DarktableLand!
    I cry 🙁

    star@star:~$ cd darktable1
    star@star:~/darktable1$ ls
    _MG_2011_01.tif _MG_2011_02.tif _MG_2011.tif
    star@star:~/darktable1$ enfuse-mp -o hdr.tiff –exposure-weight=1 –entropy-weight=0 –saturation-weight=0 *
    enfuse-mp: команду не знайдено
    star@star:~/darktable1$ enfuse-mp -o hdr.tiff –exposure-weight=1 –entropy-weight=0 –saturation-weight=0 *
    enfuse-mp: команду не знайдено
    (команду не знайдено translate : command not found)
    Where there is an error?
    Ubuntu 16.10

    • Ah ha, I see that you don’t have enfuse-mp installed. This command will install it for you 🙂

      > sudo apt-get install enfuse

  5. Harry! Please tape all Terminal commands in this lesson. This command don’t work in Ubuntu 16.10 : enblend-mp -o hdr.tiff –exposure-weight=1 –entropy-weight=0 –saturation-weight=0 * 🙁

    • Ah ha, you’re right I should include the terminal commands in the notes.

      You were close… it’s enfuse-mp instead of enblend-mp 😉

  6. Hello, Harry.
    Nice to greet you for the first time!
    I like watching your processes. You are really conscientious and you know in advance quite well what is what you want to do to an image. I learn a lot.
    Nonetheless, i must note that I don’t agree with you when you say that one way of increasing the exposition is by means of tone curve or levels. As far as I know, base curve and exposition work in RGB, whereas tone curve and levels work in Lab. The result is quite different, mainly in relation to the colors. I’m not sure about the difference between base curve, raw black/white point and Exposition, but the results using one or the other seem to be more uniform.
    I may be wrong, though.
    Thank you

    • Hello Marcial,

      You bring up an excellent point. And the main reason I find myself working in Lab. The color space is much better preserved (with scale-chroma: automatic), than in the RBG model.

      The base curve and exposure seem to work in a similar way, except the base curve allows for fine tuning a gamma component. You can try this out by comparing a snapshot of lowering the white point on the base curve, to increasing the exposure. The results on the screen and in the histogram are the same.

      It’s nice to meet you too 🙂
