"bluring" huge amount of spots

[dancebles]

hi

i want to clean a lot of photos of products which are not clean. i'm including a high resolution sample.

where can i find an easy tutorial on how to easily "blur" such things?

most products aren't white so there are not many that are such problematic.

i'm using inpainting for some products. but i can't clean so many spots of samples like that.

i will use the end photo as low res so it doesn't have to clean it for the high res version.

thanks once again

Have you tried the Dust and Scratches filter (Live or destructive)? The settings will depend on the size of the image but it does a pretty good job:

Watch out for 'rounding' in the corners of the image though.

I am not familiar with this filter but does not the Preserve Alpha check box take care of that corner problem?

It does ... kinda. There is still rounding at the corners but it isn't transparent.

thank you very much

 

i will check it myself now (the filter )

WHAT A MAGIC

it works

 

thanks and love from israel!

With Preserve Alpha checked, at higher Radius values I get this is in the corners:

 

 

That's on the OP's original screenshot though, which is a very small low-res image. With larger originals the issue isn't anywhere near so obvious, and by the time you reach a point where it kicks in, the original is so degraded as to be pretty much unusable anyway.

(Could make an interesting artistic effect though...)

Does make an interesting artistic effect.

Fixed it for you!

hi again,

for some reason the "Dust and Scratches filter" is good only when im zooming in.

i mean, when i zoom out, a significant amount of "dirt" still appears.

do you know what might be the cause?

TTNNXX!!!

[NotMyFault]

If you zoom out, the rendering might not correctly show the effect of filters like sharpen or dust & scratches. Simply merge visible to get an accurate rendering. 

It would help us to solve your issue if you can upload the original file, or at least a big enough portion, using a lossless file format (e.g. afphoto, or a zip file with tiff etc)

personally I’m no big fan of d&s filter as it can produce hard edges. You need to really tweak the settings to get a good result.

Depending on your specific file, a blur filter like bilateral blur might be better suited.

Without knowing the effect on the rest of the image you could blur the hell out of that sample and it would not be relevant if whatever isn't being affected so we can't have a point of reference.

 

[NotMyFault]

Thats why i asked for the document 😂 

[dancebles]

i will add a sample later

for now, just want to be sure, are you talking about the "merge" button left to the 'delete' button? (screenshot attached)

because if yes, i'm not sure what to do after pressing it. there is a weird mouse curser and weird behaviour after i press it.

or perhaps you meant something else?

 

EDIT

the merge option works fine now. but not on all files that i'm editing. i mean, there is one file that shows this mouse curser for some reason. i can't add a screenshot of the curser when i 'print screen' tho.

That is not what was meant but unless you describe what kind of weird behavior you get if you press that button, there is no way for us to know what is happening that might be weird.

@dancebles:

merge visible is available via layers stack, right click, merge visible

 

@firstdefence

please have a look at the doc attached file. I've added vector shapes with 1 px and 5px stroke, and 2 blur / dust & scratches filter layers with identical settings (30 px  / 10%).

The d&s does far more harm to the thin lines vs. the bilateral blur. (enable them to check result).

ok people,

so it's on the menu

i understand now.

it was conusing because there is a merge button too....

Why would you ever want to apply a D&S filter to any vector shape layer(s)? 

[NotMyFault]

It is only an example to show what happens to thin lines or edges when you use dust & scratches filter, and how bilateral blur differs with respect to them. You may rasterize / merge visible to get an pixel layer, does not impact the result. I'm still waiting for the document from dancebles to see what actual complications are in there.

 

The point i want to show is that bilateral blur better removes small scratches, and preserves other thin lines / edges better than dust & scratches.

I am not sure if using those vector shapes with perfect edges, even if rasterized to a pixel layer, is a reasonable substitute for scratches, dust, or other kinds of pixelated spots which are unlikely to have such clean edges. I think that's what the D&S filter is designed for so I am not sure this is a fair test.

But what do I know?
