    Hello everybody,

    Does anyone know how to do an effective chromatic aberration correction? I’ve been trying to use Darktable’s “lens correction”, but the tool is really complex and I haven’t been able to make heads or tails out of it.

    Any and all relatively educated answers are appreciated.

    Just recently I learned how to remove it in Photoshop from this video. Jimmy McIntyre’s sits seems to be clean-but I have filters on.
    I have fond the methed he shows to work well. (I used the one with the free action).

    “lens corrections” is to correct vignetting and lens distortion (pincushion/barrel distortions)

    There is another module called “chromatic aberrations”, if I remember rightly.

    Good point, David Frazer. But “chromatic aberrations” only gives me an automated chromatic aberration correction. Sometimes, it does a good job, and other times it doesn’t.
    Specifically, I was wondering about the TCA (Transversal Chromatic Aberration) red and blue sliders under the lens correction module, as shown in the screenshot. Is this exclusively a lens-specific correction?
    Thanks Blessingscaptured, I’ll look into the link you sent.

    Check out the “Defringe” tab in Darktable, that may be what you’re looking for. Here’s a video that demonstrates:

    NOTE: I linked the video to start at the 14 seconds mark instead of the beginning. (There’s a reason for that…) Otherwise, the video itself seems pretty clean.

    Note to other readers: Please remember that Youtube videos often have side-bar content that contains inappropriate content. If you want to learn how to keep that content from showing, check out my tutorial here:

    Note to self… Those videos are out of date, I think I need to redo them. 😐

    Thanks buddingphotographer, I think that will really help.
    He seems to be really able to produce good results with that.
