[By design] is the dust and scratches working?

Recommended Posts

I tried to use the live filter dust and scratches and really it does not seems to work.

"Does not seem to work" could be open to many interpretations.

As far as I can see:

With 32-bit RGB images, both Live and Destructive versions of the filter are disabled (greyed out).

With 8-bit and 16-bit RGB images, the filter has some effect at low tolerances but doesn't add what I would consider to be dust, scratches or both:

(the video is 16-bit Destructive).

Similar effects with LAB colour - haven't had time to test this, or CMYK, or checking and unchecking the Channel Tolerance button.

(I have Metal enabled - haven't tried the other way.)

Possibly. Or possibly from photos taken while you have dust on the camera sensor, if your camera has interchangeable lenses.

As an example (and to cover my earlier embarrassment): I have an intractably stuck piece of dirt on my sensor which shows up as a dark mark in plain sky backgrounds.

I could get rid of the mark using Dust and Scratches by creating a Live Filter layer, adjusting the settings until the mark is no longer visible, then inverting the Live Filter layer and painting over the mark in white:

 

 

 

However, for a quick fix I reckon it's probably more effective to use the Inpainting Brush - certainly fewer steps.

Not sure i follow that logic, yes it works, but why not using the inpainting brush tool. One step instead of three...and yes you mentioned that. 

But I think that there must be another reason for that dust and scratched otherwise just useless unless for older photo or something like that

The Inpainting Brush is destructive. I suppose if you wanted to keep the original dusty scratchy image then you could use a live filter.

The Inpainting Brush can be use non-destructively

Hi all.

@srg you still have not confirmed what @>|< was asking... Is your document 32 bit? Were you using it incorrectly? (thinking it adds dust and scratches rather than removing them)

Can we close this issue now?

Thanks,

Gabe.

No,  I was not using the 32 bit. sorry if I overlooked this, and yes I was thinking it would add.
