Lightroom: Add a New Effect to Remove Dust and Scratches from Object Surfaces

I recently did a lot of product macro photography. Here I usually have some dust left on mirroring surfaces. So it is part of a workflow, where I have annoyingly switch to Photoshop and back to Lightroom.

- I have to work on the dust as one of the final steps, because first I have to fix the exposure and all lights before I see where I have to remove durst and where i is not visible.
- If I later find some issues with the lighting and adjust them in Lightroom, I have to do all the dust removing work in Photoshop again.

Therefore I suggest a new "Effect" in Lightroom which is basically the "Remove Dust&Scratches" filter from Photoshop. It is important that this filter can be combined with masks, because of the resulting blur, I only want to apply it on flat surfaces where the blur is not visible.

Have you tried the Spot Removal tool in LR?

I don't understand your comment about having to remove dust twice. Once dust is removed it's gone.
In PS you should be saving the image as a TIFF or PSD that included all the edits from LR. 
So you are saying you go back to the original RAW file to do those other lighting adjustments. Try doing them on the PS saved TIF or PSD instead of the original RAW image.

Yes, I use the spot removal tool in LR for large dust particles. But it not practical for thousands of small durst particles (as shown in the image). (The sport removal tool from LR also performs poorly compared to the one form Photoshop, but this is another topic)

About the adjustments: Sometimes after all work is done, I have e.g to adjust the white point of all images. This will also affect the visible dust, sometimes more dust appears at the edge of already processed areas.
  • If this would be an effect in LR, I could just extend the mask of this effect a little bit where new dust shows up.
  • With the current ¬†state, I would need to re-edit the already edited photo again. And because it is a edit where details get lost, it is not optimal.
  • Last, I would like to keep one single copy of each photo with the raw image data and only store edits as delta. Here I have always a second (edited) copy of each image stored in my library.
