I have a photo that is not of very high quality and and these kinds of small cracks all over its surface.

enter image description here

Is there a way to reduce this effect?

  • Hi. Welcome to GDSE. Can you share the entire photo? It's difficult to differentiate between what parts are cracks, and which are details. All I can really see is some sort of texture. – Billy Kerr Nov 28 '19 at 19:38

You can use luminance noise reduction, but the overall result will be to lose detail.

If that is part of a much larger image, sharpening or using high-pass on the result might regain some apparent edge detail, but on that small segment it's hard to tell.

Quick bluff through Photoshop, no re-sharpening as I don't know what needs to be sharpened from so little information…

I ran a high-pass too, but with no real hope of knowing which detail needs to be recovered it's a total guess…

A better guess could be made from the full image - blur or blank out any personal details, faces etc, if you need to.
