Episode 045: The Right Colours! (nearly…..)

Today there will be something different for your ears first – thanks to John Pazdan. I like his stuff very much!

Inspired by this discussion in the “Meet the GIMP!” Photogroup at 23hq, I tackle the begin- nings of monitor calibration. For an in depth look go to the page of Norman Koren

You can use this web page from Cambridge in Colour for a start. Then there are tools like Monica for correcting your display.

The DQ tool for getting better prints can be found at the site of the Photo Industrie Verband. Scroll down at the right sidebar and you’ll find it at the bottom. (Have I ever told you how much I like pages without the possibility of a direct link…..)

All this can be helpful for the amateur. But keep in mind that it is no replacement for a complete colour managed workflow. If you really need that, then you have to invest in some serious hardware and time for setting that up. Joel Cornuz has a series of articles covering the Linux aspects of colour management. Perhaps some of you can share links to sites for MacOS and Windows.

  1. Thank you for the video which was quite interesting but, more importantly, you said something which I think is very significant. You pointed out one of the differences between transmitted light and reflected light. If we extend that to what the camera saw and then what we see on the monitor when viewing that image, the same difference must apply. So. logically, provided that all the processes are set correctly, the final print should be what the camera saw and not the image on the monitor. What do you think?

  2. Thanks yet again for your work and patience teaching us GIMP!

    I am looking foward to this episode and downloading it as I type.

    I also wanted to mention that Full Circle Magazine has started a new series in their latest issue titled “Using GIMP”, thought you guys might find it interesting, here is the link:

    Greetings from Barcelona!

    BTW, your last episode was great, who said germans have no sense of humour huh?! 😀

  3. @Norman: It can’t be that what the camera saw. You’ll never get the intensity of sunlight reflecting from water drops or the wings of a butterfly from paper. And you’ll never get the blackness of black velvet or charcoal from ink or silver.

    Our world is so full of contrasts and colours – we can only make a dim image of that.

    More important yet: My images shall not show what the camera saw or what I saw, but what I want you to see! 😉

  4. I watched this last show and thought about what you said on helping the show out, so how about making the show modular?

    Take, for instance, a photography skill and commit a month to it, like wedding photography.
    * First show could be the gear you need, general advice before you even head out the door.
    * Second show could be how to handle the people being photographed, general poses and tips and tricks on the shoot itself.
    * 3rd show could be post processing the images in Gimp
    * 4th show could be an questions and answers show.

    Then on to the next month tackling wildlife or whatever.

    This way you cover a huge range of stuff and you can always revisit all the shows with new information in a specific month, maybe someone who is a professional ion his field will make a contribution, etc.

    Hope this gives you new ideas for the show!

  5. The reason I raised the issue of what the camera saw is because there has been correspondence on the topic of the camera and the monitor in another place. When I produce a final image, be it for the monitor or the printer, I try to make it what I want as a piece of art and try to use the camera and the software as an artist uses canvas, paint and brushes.

  6. @JJ Sounds like a good idea but is not doable for me. It would need too much work in prepration and planning. This is a spare time project and has to stay in a reasonable time frame.

    If I could charge a € per view, I would quit my job, make a better podcast and have a DSLR as price for the then monthly photo challenge. 😉

  7. @Norman: Good analogy. And as the painter has to know what the dried paint looks like, we have to know about the monitor and the printer. The camera is not that important, I think. You can always correct it’s output.

  8. Thanks Rolf for yet another good show
    to answer your constant request for suggestions to
    make the show better
    frankly I don’t think it matters much which way you go or do
    your teaching style is perfect and just works well

    if anything perhaps setup a request box of some sort
    that people can add items to that they would like to learn
    about and others could vote on which is a priority

    the one item I find that the site could use is a episode guide
    its to hard to skim the blog posts to figure out which episode covers the item one is looking for

    also why not switch to a 16:10 (or 16:9 if you think people want to watch it on tvs instead of computers) format on the
    video then you will have a bit more room for everything
    then you can stop having to shuffle everything about as much

    I look forward to further episodes

  9. Great blog! I love it!
    As another fellow Linux enthusiast, I’m marveled to see this blog full of rich
    information. It has been due to have such good material covered.
    While it is true that Open Source software has been all around us all along,
    tutorials on the other hand have not.
    And while everyone seems more focused on teaching the leading Image Manipulation Program (a.k.a Photoshop), your
    blog is enraged in showing the world the wonders of the GIMP.

    At last I can start learning it myself, since I’m also a GIMP beginner.
    Please continue your hard work. It is greatly appreciated.

    Godspeed on your Blog and keep teaching us about the wonders of Image

  11. I’ve been looking for guidence in printing with GIMP for a while, so this video was usefull for me. Especially the links to different tools is appreciated.

    Thanks alot!

  12. I believe you said you owned a Spyder. I have just had some success with dispcalGUI, a front-end which
    eases a lot of the difficulty in using ArgyllCMS. I mention this because I believe this front-end has tackled
    all of the difficulties involved with using a Spyder (I do not own one and so cannot comment).

    I created a medium-size profile with gamma of 2.2 at 6500k (these seem to be the universal standard
    these days) which took about thirty minutes (a long time to sit holding a colorimeter onto your monitor).

    The hardware solution to monitor profiling is a great option for people like me who cannot consistently
    recognize a colour cast in their pictures or monitor. In terms of these, I generally try to make skin tones
    convincing, but this is obviously not possible for every type of picture.

Anything to add from your side of the computer?
