Dust map / dust reference

Feature Request

I just got Macro Studio and am really enjoying it so far. One feature I’d really love to see added is a dust map / dust reference.

At very high magnification, even tiny residual dust spots can become curly lines or trails after alignment and stacking, and these can be surprisingly difficult to remove cleanly in post-processing.

Being able to provide a reference image for automatic dust correction would be a very useful addition.

    @Cornel Pacurar actually if you have a moment, can you send me one of your problematic stacks through the app? In the Editor, you can right-click the thumbnail (or click “Share Feedback” at the top) and “Send Stack”. That way I can text the fix on your exact frames.

      Hi Ryan - absolutely. I actually just shot a new 20× stack that should be a very good test case. It has a large smooth background area where the curly trails are particularly obvious. I’ll send it through Send Stack now.

      Thanks for looking into this!

      Hi Ryan, the upload didn’t go through because the 415 source frames total 9.8 GB and exceed the upload limit. The curly trails become increasingly apparent with larger numbers of source images, so I’m not sure a small subset would reproduce the issue as clearly. Let me know how you’d like me to send it.

        Thanks, Cornel. I’ll email you a Dropbox link.

    Hi @Cornel Pacurar - thank you for suggesting this. Actually I’m finishing some improvements to my chromatic aberration / defringe processing that I THINK will take care of this. Should be releasing that update on Saturday, worst case Sunday. Once that goes out, I’d love for you to re-run the problematic stack(s) and tell me if those lines/trails go away! In the meantime, make sure you try Spot Correct, as it’s usually pretty good at fixing those. It has a Heal mode (where it sample nearby areas to find a match) and a Clone mode (where YOU pick the “donor” area).
