Hello,

In the musical score I send you, I would like to remove the dust at the bottom right.

I have tried to use the Dust filter, but it removes the image quality

Is this a simple way to do it while preserving the image quality ?

Convert to greyscale.

Use "Levels" as shown on the screenshot.

And finish by removing any remaining black marks with the Eraser, the Remove tool, or a selection tool.

Select all the image (CRTL/CMD - A) : Generative Fill : select Gemini 2.5 (Nano Banana) and prompt : "set to black and white, remove dust".

It won't take you longer than a minute.

You may need to increase the sharpness afterwards.

What a relief 🙂 I mean it.

You just have to use a small enough brush with e.g. the healing brush so that you stay away from the notes. It's not difficult, it just takes a little time.

As a help, you can select the paper color and expand the selection one or two pixels. That should be enough to "eat up" the dust spots, but not too much into the notes. Then you can work a little more freely.

My need in that case is to remove the dust inside the notes like here :

But by example if I use the lasso tool directly on the notes (where there is dust), and use the filter "dust", the notes becomes blur. I am wotking with the background layer.
