How to edit out a smudge and scratches from a photo?
There's a smudge of chocolate or something right above my head (the kid on the left). The yellow/red marks are from when my brother tried to scratch it off with his fingernail and exposed the background. How do I get this to look presentable? Huh

Sorry about the huge picture, I don't know how to adjust the size.

RE: How to edit out a smudge and scratches from a photo?
One good way I would use the (resynthesizer) heal-selection toolplugin. The one with the options not just the radius. It attempts to clone the boundary of the red/green smudge. You use the selection Freeselect tool & select a little area at a time and it will automatically clone out around it.
It will be as if it was never there Smile

It works with 2.8.6 on xp, will test it soon on w8. But if you want to try to install the plugin in here's what you need are two things you will need.
heal-selection script
http registry gimp org/node/15118

resynthesizer plugin (to work alongside heal-selection
http://registry.gimp.org/node/27986

A second way is to use the Heal heal brush tool(clone tool if it doesn't look right.) Push ctrl to define a clean spot, then click on the affected area. Try making the brush size around the same size of one of the red marks.
   

The heal tool is like clone tool's older maybe stronger cousin
http://docs.gimp.org/en/gimp-tool-heal.html
http://docs.gimp.org/en/gimp-tool-clone.html

The clone spot is the circle with the cross in the middle, that one should be static until you heal clone over the area, then you can see how it works.


I can't show you the resynthesiszer one yet because I'm working on a new computer right now, doing updates & I don't have the plugin/script installed yet. Maybe later/Thursday.

EDIT: Ok on here there is one good example of resynthesizer & I found a page with final result examples
(See the post image "Results like this: ...")

This is a great response and just what I was looking for, but I noticed that you seem to have already done it though. If you have, do you think you could you post the new photo?

Great news! I installed the resynthesizer, ignore that link to heal-selection, that's an outdated script, its all in the resynthesizer plugin(much cleaner effect.)

I only edited part of the photo for the above example, would 1024 x 768 be a good size?
I can clean up the scratches with curves tool and heal any white dots/scratches.

If so I'll have it to you maybe thursday night, have work most of the morning.

In the meantime.
File open your photo in Gimp & scale your photo to 1024 (click the link icon to constrain proportions)
Image > Scale...
Then try the heal tool Heal like I did above. Good luck & if it doesn't look good no worries just wait until later Thur or Friday.

RE: How to edit out a smudge and scratches from a photo?
Here is my stab at it.

As previous posts, resynth + heal tool takes care of most. The big area is not really a problem it is surrounded by a uniform texture.

Small details, eg. car reflection in window where you are guessing what was there originally are more of a problem.

Finally a de-speckle over the background. The speckles are there in the foreground but not so noticeable, best to leave them rather than degrade the image further.

Maybe 10 minutes work. You should be able to open this link and right click 'save-as'

but don't rely on anyone else, get gimp up and running, tryout the various procedures mentioned. You only learn by practise.

RE: How to edit out a smudge and scratches from a photo?
I like the despeckle filter, but it kinda blurs the image(but sometime it works!). Great job nonetheless rich imo! Smile

Here's my try using just heal-selection, heal tool & curves. About the same amount of time,
I brought the curves/levels down a bit to get rid of overall haze/scratches. Lightly-auto-color enhanced & heal tool brushed the extra. I cleaned out the graffitti & the stray branch just for kicks lol.

If you do choose to try resynthesizer(which I recommend you try, the end result is fun Smile )
-Resize(Image > scale image...) your image to max 1280w (faster loading) click the link icon to lock height to width.
-Then select similar & input the settings seen in the below pic.
   
.
Final Result after minor cleanup(color enhance, scratches)
    *Click for full size

Have fun gimping & pace your self if you have time, do a few steps one day, save as... "name.XCF" & continue working on it later on.
