Photos - removing granular and blurring

GIMP Version: 2.8.14
Operating System: Windows
GIMP Experience: New User

Hi All,

I have a photo taken with a point-and-shoot camera by an inexperienced camera-person.

It's a good photo I can't replicate and I'd like to use it in a packet.

I read "Grokking the GIMP" and Googled
how to fix granular photos using Gimp" but got mostly irrelevant results except one person agreed with the Grok author - use Unsharp Mask.

I tried that and it made no difference.

Another site suggested using Filter>Noise ...but that didn't make the photo any less granular or blurry.

Could you please share what's worked for you in Gimp reducing graininess and/or blurring?

Thanks so much!

Any chance of posting it ?

Have you tried Wallace's deblurr filter? It's under filters>enhance. You can get the script at Gimp Scripts.

Hey 2-ton,

Thanks for that suggestion.

I visited this http://gimpscripts.com/?s=wallace ..but couldn't seem to find Wallace's deblurr filter.

Is that the correct site? If not, could you please share the correct site?

Thanks.

+1, can't make suggestions without seeing what the problem really is...

I totally agree with Ofnuts: no possible suggestion without seeing the image (or part of it if confidential)

Hi Wallace,

Thanks so much for sharing that link.

I downloaded that file.

Could you please share how I would then install it so it becomes part of Gimp?

If I click on the file does it automatically install into Gimp so I can then see it under Filter >Enhance or does it install under another Gimp tab?

Thanks so much for all your help.

The .scmfile,
needs to be placed into your Gimp User scripts folder.

I'm using Windows 10 and my Gimp Uses scripts folder is located at;

C:\Users\Wallace\.gimp-2.8

This is what is inside my Gimp user folder.

Hey Wallace,

Your application does clear up the blurriness quite a bit!

The overall photo is still very grainy.

I wondered if there's anything more I might try to make all the photo less grainy?

Thanks so mcuh for all your help.

As others have suggested.
It might be advantageous for you to post the image or part of it.
To get more accurate suggestions for how you might correct or improve the image.

However,
you could apply a selective blur and the use deblur.
Even so it's hard to say if this would work or not,
without seeing the image.

Here's part of it.

Thanks.

Maybe

FFT (the regular plugin) followed by some sort of sharpening - used octave sharpening here (g'mic plugin)

I used G'MIC repair, Iain's Noise Reduction. Played with all the sliders to get the best I could. Then in Gimp a little unsharp mask. I did not spend a lot of time so you may wish to refine more than I did.

Rich,

Where would I find FFT (the regular plugin) and the octave sharpening (g'mic plugin)?

Thanks.

Hi Pat,

Please forgive my ignorance but where might I find “G'MIC repair, Iain's Noise Reduction”?

Once found, do I simply download it to the scripts folder like Wallace’s deblur file .scm?

Merci!

Not really beginners stuff, but

Fast Fourier Transform (FFT) plugin http://registry.gimp.org/node/19596
for Windows 2 files an .exe and a .dll both go in your Gimp profile C:\Users\your-name\.gimp-2.8\plug-ins
The plugin appears in the Files -> Generic menu

G'mic
http://www.gmic.eu where there is a link to a windows installer.
Lots of sharpening filters there in the enhance details section.

I think this is a scan from a home printed picture, not a photo straight out of the camera.

G'MIC is something you can use.
Repair>Smooth [nlmeans],
Smooth [selective gaussian]
Smooth [diffusion],
Smooth [anisotropic].
Play with sliders.
Combine the best of them in layers.
Eventual thereafter: G'MIC Details>Sharpen [richardson-lucy]

Go to: http://gmic.eu/gimp.shtml and download the proper G'mic script for your operating system. I have windows and the installer with the script will do the install in the proper place.
G'MIC is found at the bottom of the filters menu in Gimp after installed. Open it and go to Repairs. There are many tools there to fix photos. I started with the Iain's Noise reduction. You may want to try others.

Rich, Iarga, Pat,

Thank you all so very,very much for all your help.

Do I need to install that .exe file to G'mic into C:\Users\your-name\.gimp-2.8\plug-ins or can I just download that installer to my C:\Downloads folder where I download most of my programs?

I'll also be downloading and trying the Fast Fourier Transform (FFT) plugin.

I'll try everything and anything which might help.

I really appreciate you all playing with this photo and kindly sharing your suggestions, links and experience.
